Hats and Scarves for Cold Weather Cycling: What to Look For

This Fall I've been sick a lot, so I am using the downtime to knit. After making a couple of skirts, I moved on to a special project: hats and scarves specifically designed to resist the cold and wind while cycling.



While it may seem that any hat and scarf should be sufficient for this, last winter I discovered that this wasn't so. Store-bought knits can be a mixed bag in terms of how well they work, even if they "look" warm and cozy. So while making my own, here are some criteria I've come up with that may help as you're winter shopping.



1. Adequate coverage



This may be obvious, but a hat is most effective if it covers your ears. It should also be tight enough around the opening so that it does not slide while cycling - especially if it's windy. For me, hats that are "slouchy" are often too loose and quickly slide off my ears - or off my head entirely - when I cycle. I solved this problem by making the openings on mine extra tight, and you can watch for that factor in store-bought hats as well.



As for scarves, they can often come loose and unravel, or at least slip in a way that exposes your throat to the wind while cycling. If you have found this to be a problem, consider getting what is called a cowl neck, or a neck warmer instead. This is basically a thick, knitted turtleneck, without a sweater attached to it. You slip it on over your head and tuck the bottom under the collar of your coat. Unlike a scarf, it stays put and provides adequate coverage - even when cycling against the wind.



2. 100% wool



Assuming that you are looking for knit hats and not forsportyhigh-tech fleece, pay close attention to the material. I have been amazed to discover just how much better 100% wool is at keeping out the chill than a blend that includes even a small percentage of cotton, acrylic, or other materials. It can be convincing to see a fluffy knit hat with fair isle patterns of reindeer on it - but if it's even partly acrylic or cotton, it just won't work as well as wool.



Some might worry about wool feeling scratchy agains their heads or necks, but today it is easy to find wool with soft textures - wool that feels cotton-like or silk-like. While cashmere is nice, it is not necessary if you can't afford it. To me, peruvian alpaca has a very pleasant feel to it, and it is fairly affordable.



Even a gauze-thin wool hat can be surprisingly effective against the cold and wind while cycling. I made this one when it was still summer-ish, but it works well even in November.



2. Dense stitching



It is easier, less time consuming, and requires less wool to make a loosely-knit piece than a tightly-knit one. Chunky, loose stitching also "looks" warmer. But in actuality, it means that the knit is more porous - making it easier for the wind and the cold air to pierce right through it. If you want a hat or scarf that will really provide an impenetrable border against the frost and wind, look for one with dense stitching, and not necessarily in the chunkiest wool possible. It will be more functional.



Cycling in the cold is a special challenge for knitted hats and scarves, because they need to remain effective when you are moving against the wind at 10-20 miles per hour.I own lots of knitted accessories, but when the temperatures fell to below freezing last winter, I discovered that only a few of them truly kept me warm.Pieces that provide full coverage of the ears and throat, are 100% wool, and are densely knit, will be up for the job where others fall short.

A quick fix for the "new" Nomic or Ergo pommels..

Petzl is now offering to fix anynew tool under warrenty. Petzl'sis adding a pin through the pommel which is a much better solution than epoxy imo. Petzl was quick to respond and offer a fix and a replacement. They are a good company to support.



This is not an authorised Petzl solution for beefing up the pommels on the new Nomic and Ergo but it is the best I can come up with and not alter the handles.



Alter the actual tool handle and you void the warranty. Which you don't want to do!



The issue is that the pommels themselves are stripping out the adjustment system and wrecking the handles.

Pommels are easy to modify and inexpensive to replace. Petzl should love what I am about to suggest as it willprotect both your investment and Petzl's at least in the short term.



Couple of cautions first from my own experience. Make sure of the size you want the grip set at. Doing what I will suggest makes them bolted and glued into placeat only onesize. You could buy extra pommels when they become available through Petzl and do the same thing but with a different hand size setting if required. And have another size grip, bigger or smaller or all three. Just takes a extra pair of pommels for each grip size you'll require.



I found that I could climb on the smallestsize settingon the first day but by the second day of climbing my hands were swollen enough that I had to go up to the medium setting as the smallest size had become just a bit too tight and slightly painful. And these weren't the first days of the season for me.



That surprised me as the new tools have slightly different settings from the original Nomics. A bit smaller and a bit bigger in the same settings it seems.



OK, the short term fix? I used an industrial strengthsteel epoxy to fill in the bottom of the slot inthe pommel.But first and the most important, if you want to maintain the warranty, is be sure to use an epoxy that can be usedwith arelease agent. I used Steel Bed from Brownell's. (http://www.brownell's.com/) A number of similar products out there but that is one I am very familiar with. It will certainly reinforce the pommels...but no idea if it will keep them in one place long term. Seriously...I doubt it. Knowing the abuse these tools take it is not the best answer but an easy fix, short term.. But not a lot of options at the moment either.

Back to the fix I used.



Be sure to give the end of the shaft a liberal layer of release agent and cover everything including the nooks and crannies. Then add just enough epoxy (a layer 3 or 4 mm thick in the bottom of the pommel cut should do) of your choice to have it pushed out the end of the pommel on either side when you bolt your pommels back on. It won't take much so don't over do it here. Make sure the pommels are in the correct position that you choose before starting. Make sure both tools are the same position! Wipe off the excess that was pressed out when you slide and then bolted the pommel down. Let the parts drythe suggested 24 or 36 hrs. The longer the cure time usually the stronger the resin-epoxy bond's strength.



I'm off for 5 days of ice climbing in the morning so we'll see just how long the "fix"lasts.





Factory shaft with umbilical attachment hole pre drilled and beveled by Pertzl. Nicely done. And the three obvious pommel adjustment notches that are failing on the right hand side of the shaft.

4mm cord easily fits into the factoryumbilical hole if you want a lower profile umbilical attachment.

Cord and pommel in place at the medium setting..but not bolted down yet. It had better be right when you put this all together because you won't be moving it again other than to replace it after you have added the epoxy bedding material.

Easy to see here the tiny bit of pommel I groundoff to fit an umbilical clip cord if that is something you want to do while you are working on the shaft. The new pommels are aneasily replaceable part and inexpensive.



In the pictures below I am holding the pommel so you can look down into the shaft's slot and see the single steel engagement tooth. I laid a thick layer of Steel Bed Epoxy into that slot which covered the single steel "tooth." Putting your chosen bedding compound-epoxy here will help prevent the shaft end of the tool from being strippedout by excess movement of the pommel in hard use. The idea is to reinforce the steel notch pin in the pommel by addingsome support with the steel based epoxy in the other adjustment slots.



If you want to run umbilicals Petzl has made that easy now by the hole in the shaft able to take4mm or 5mm cord. Easy to grind off the back end of the pommels and thankfully not change the feel on the grip. 4 or 5mm cord will generally be about the same strength as the commercial umbilicals like Grivel's and BD's.

After the Heat Wave


With July's heat wave becoming a memory, we look forward to cooler temps on the upper mountain. Freezing levels have dropped back down to ~12,000 feet. Check out the Route Conditions on your intended climb for updated reports.

It is that time of the year...

It is indeed that time of the year. I was hoping for some rebate luck but looks like this year will be a dry one with no change, but maybe I am wrong with my math. We will see. My suspicions are there's more blue envelopes coming down to visit my mailbox.

This year the Belastingdienst (Dutch Tax Department) is penalizing tax payers who do not file their taxes on time. I am cramming!

We pay incredible high taxes in this country, with 4 tariff brackets depending on income: 33.45% (only if you are earning below 18K euros a year), then the normal brackets starting at 41.95%, and then 42%, and finally, the highest income tax bracket, 52%. Yep, we pay 52% tax.

Plus more taxes if you decide to spend less and save more. With the new tax return the government wants the account number/s of your bank/s and the corresponding moolah in it, beginning of year and end of year. Tsk, tsk, tsk...

I just hope my tax would be put to good use by the government. Or maybe that is a joke.

Who's Afraid of Toe Overlap?

The idea of "toe overlap" or "toe clip overlap" (TCO) is one of those hot button topics that can causemetaphorical bloodshed in online discussionsamong bicycle enthusiasts. Still, I would like to have a go at it, as I think my perspective reflects the type of cyclist who does not typically take part in these debates. I would also like to discuss the topic from both sides of the argument, encouraging readers to form their own opinions. In short, here are my 2 cents:

What is toe overlap?On some bicycles, it is possible to hit the front wheel with your toe when turning at slow speeds. This interference (or overlap) between your toe and the wheel can make you fall. Toe overlap is especially common on bicycles with small frame sizes and large wheels. If you picture what happens to the wheels of a bike as the frame gets smaller (as the top tube gets shorter, the wheels move closer together), it makes sense why that is so.

Is toe overlap a problem?

I don't think there is an answer to this question that rings true for everyone, but I will try to cover multiple sides of the argument.



An argument for "no": Chances are that you alreadyhave a bike with toe overlap and simply haven't noticed. Try it: make a slow, sharp U-turn on a quiet street or in a parking lot, and pay attention to whether your toe can potentially hit the wheel as you are making the turn. The overlap is more drastic on some bikes than on others, but most smaller-frame production bicycles have it to some degree. The reason many cyclists remain blissfully unaware of it, is that we rarely cycle at speeds slow enough for the wheel to turn so sharply as to cause the overlap. So while the overlap is a theoretical possibility, it is not usually a threat.



An argument for "yes": Cyclists do occasionally make turns slow enough to cause toe overlap. Instances when that might happen include the aforementioned U-turns, as well as slow turns in urban traffic. In addition, beginner cyclists tend to go slower than experienced cyclists - making them more vulnerable to toe overlap.



An argument for "no": Some in the bicycle industry will argue that toe overlap is not so much a "problem" as a reality, and it is the cyclist's responsibility to learn to deal with it. Even on bikes with dramatic toe overlap, and even when those bikes are fixed gear (i.e. coasting through a turn is not an option), there is a way to time your pedal strokes so that your toe does not hit the turned wheel. There are formulas and instructions for this. Over time, it becomes "second nature."



An argument for "yes": What is "second nature" to some, may not be to others, even over time. There are some experienced cyclists who've had bad falls as a result of toe overlap. The bottom line is, that if your bike has toe overlap, and if you actually manage to hit the front wheel with your toe as a result (or get your toe jammed in there, which also happens), you could have a bad fall while trying to execute a turn. Therefore, at least in theory, a bike with toe overlap is more accident prone, than a bike without. Some would argue that this in itself makes it a "problem" and not just a "feature" of the bike.



What can be done to avoid toe overlap on small size bikes?

In theory, a few things can be done by the framebuilder or manufacturer to create small size frames without toe overlap. The problem is, that all of these changes have consequences that can be perceived as drawbacks. For example:



Smaller wheel size: Toe overlap can usually be eliminated on a small frame by fitting the bike with proportionally smaller wheels. For instance: 650B instead of the typical 700C on a roadbike, or 26" instead of the typical 28" on a roadster-type bicycle. The reason this is seldom done on production bikes, is that it is more costly for a manufacturer to design different sized frames around different wheels. Additionally, cyclists themselves tend to have an aversion to smaller wheels, due to a commonly held belief that larger wheels are faster. This makes smaller wheeled bikes less popular, despite their no-TCO advantage.



Changes in frame geometry: Toe overlap can also be eliminated by a number of changes to frame geometry. The simplest method is to make the the top tube a bit longer and the seat tube a bit steeper, which will create more space between the front wheel and the crankset without changing the way a bicycle handles too much. However, a longer top tube means that you will either be too stretched out on the bike, or will need a super-short stem. And a steep seat tube means that you may either be uncomfortable with the aggressive angle, or will need to find a seat post with considerable set-back. If you prefer a relaxed seat tube angle and a reasonable top tube length,then the other options are more complicated, as they involve messing with the bicycle's handling: Making the head tube slacker and increasing the fork rake will reduce toe overlap as well, but it could make the bicycle less responsive, which many cyclists would find undesirable. I don't want to turn this into a lesson in frame geometry, but suffice to say that some would prefer to deal with the toe overlap, rather than make either of these changes to their bike.



Conclusions?

It is hard to find a definitive answer to the questions of whether toe overlap is a problem, and of how to eliminate it. Different frame builders, bicycle fitters, and other industry spokespersons will tell you different things, and they may all sound perfectly convincing and reasonable while you are listening to them... until you hear the other guy's argument for the opposite, and it will sound equally convincing and reasonable.



My personal view is that toe overlap is a problem if you consider it a problem. And if you do, then I don't think it's right for anybody in the bicycle industry to try and persuade you otherwise in order to sell you a bike. Ultimately, it should be up to the cyclist to decide and for the framebuilder, or salesperson, to accommodate.

Yorktown Victory Center

We finally made it Yorktown Victory Center. For those that don't know, Yorktown is the site where the British surrendered to the American and French troops, effectively ending the six year Revolutionary War. The Victory Center is a living museum, and we love living museums so it was a treat to visit here. We saw the encampment first:



While here, we saw two military weapons being fired. The first was a cannon and the second was a mortar. Cannons shoot solid balls and mortars shoot bombs. The man talking during each told us lots of interesting things like that.

We talked to a man who shared about the medical field during the War. We learned fun things like how bullets were removed using the finger, what they used to disinfect and anesthetize during surgeries and what things caused mass sickness. The man who shared there used to be a teacher in schools. He decided this was a way more fun way to teach/learn. We get that!

We also hit the inside museum galleries. We watched a movie and learned more about what exactly happened here and why it was such a critical part of that war. We laughed at some parts like when they talked about a drunk soldier mooning the British army.

And then we walked past the farm part to see if it was something we'd want to visit next time we come here. It was!

We had a great time here and hope to visit again when we come back.

Singing Ice



This morning was the type of morning that will live on forever in my memory. I only made a handful of images today but more so than the images, it is the sounds of the morning that I will never forget. My friends Roger, Jon and Don were up for a visit and I brought them all down to the Spirit Tree for a morning of photography. It just so happens that this would also turn out to be probably the most magical morning on Lake Superior that any of us had ever witnessed. The morning started out very peaceful. Before the sun rose everything was calm and quiet. The sounds of the snow crunching beneath our boots seemed to echo across the bay. As the sun came closer to breaking the horizon, the sky took on an incredible pink glow.

Below: This piece of ice was only a couple of inches tall. I laid down on my stomach and shot with my Canon G11 in macro mode to make this image.



Sometimes when the sun rises, you have only a few minutes of nice warm light before things become too bright. On this particular morning, however, there was a thin layer of clouds hovering just off the horizon which meant that we had at least an hour of soft, warm and diffused light. Only moments after the sun came up, the ice on the bay started to talk. It started off with just a few barely audible creaks and groans, with the occasional popping noise thrown in for good measure. As the sun got higher in the sky, the wind out on the lake increased. We were sheltered from the wind, but we could tell the wind out on the lake was increasing because before too long the ice was singing. As the wind out on the lake increased, so did the pressure being put on the ice in the bay. Ice can only take so much pressure before it cracks, and when it cracks under such conditions it makes a sound that is almost indescribable. The closest sound I can compare it to is the sound made by high tension wires when they are being buffeted by strong winds. Quite simply, once you've heard it, its not a sound that you will soon forget! Here are a couple of video clips that captured the sounds of the ice... be sure to turn your speakers up to their full volume to get the full effect of these awesome sounds!

Review of "Eustacia Vye": Pashley Princess Sovereign

[Edited to add: There is now an updated review of this bicycle here. I suggest reading the updated version first, as it's the most complete.]



Meet Eustacia Vye:my precious and unique beauty, made by Pashley and customised by the fine people at Harris Cyclery. If you are familiar with the works of Thomas Hardy, you probably got the reference of the name. (If not, read Thomas Hardy!) Eustacia roams the heaths and meadows with wild abandon, seducing those whom she encounters with her regal beauty. And she is excellent in Boston traffic.



Here are the front and back views. If you are interested in how I came to select this bicycle, you can read about it here.



I. THE BICYCLE:



The Pashley Princess Sovereign is a classic "loop-frame" ladies bicycle. It comes standard with fenders, a fully enclosed chaincase, dress-guards, a heavy-duty black Pletscher rack, a hub-driven dynamo headlight and an LED rear light, a Brooks B66S saddle (sprung, suspended leather), enclosed hub brakes, puncture-resistant Schwalbe Marathon Plus tires, a pump attached to the frame with braze-ons, an "O-Lock" for the back wheel, a "ding-dong" bell, and an enormous wicker basket. My Princess is the 20" frame (51 cm), which fits my 5'7" (170 cm) proportions perfectly. Standard specs for the Princess Sovereign can be viewed on Pashley's website here.



For those not familiar with Pashley, they are an English manufacturer and have been making traditional bicycles since 1926, specialising in transport cycles and classic English roadsters.



A close-up of the Pashley headbadge.



This is a traditionally lugged and brazed handbuilt frame. The frame is powder-coated and the paintjob is very durable (a powder coated finish will scratch and scuff, whereas a liquid-coated finish will chip). The Princess is available in two colours: "Buckingham Black" and "Regency Green." I chose the green, because it seemed to have a stronger personality, and because I generally like green bicycles. The shade is a dark and subdued "British racing green".



Pashley bicycles are made in Stratford-upon-Avon, England. Some cool photos of their factory, including the brazing process, can be viewed here.



II. CUSTOMISATIONS:



As mentioned earlier, many customisations have been done to this bicycle. Here they are, not at all in the order of importance or magnitude:



Dress-guards: We replaced the standard dressguard pictured here with a netted dress-guard I bought in Germany. I wanted a dressguard that resembled latticed wroght iron rather than transparent plastic. This one certainly does. It also covers more of the wheel than the original dressguard.



Here is a close-up of the netting over the chaincase...



... and around the opening for the "O-Lock". The O-Lock is a European locking system that locks the rear wheel, making the bicycle impossible to be ridden away by a thief. In most areas in the US, it is probably prudent to use this for supplementary purposes only.



Kickstand: We replaced the standard Princess kickstand with the Pletscher Twin-Legger, which provides support on both sides of the bicycle and lifts either the back or the front wheel off the ground (you can adjust the balance to determine which).



Not all bicycles will accommodate this kickstand, but the Princess has a special braze-on below the bottom bracket for this purpose.



Grips: We replaced the standard Raleigh-style plastic grips with Brooks leather washer grips in brown. These are probably the most comfortable handlebar grips I have ever tried: They provide just the right amount of texture, softness, suppleness and durability. And they look gorgeous!



Gearing and Brakes: But wait, what's this next to the right grip? The Princess Sovereign comes with a Sturmey Archer 5-speed hub. Mine has been replaced with a 7-speed Shimano Nexus coasterbrake hub (and yes, the gear-shifter has been twined and shellacked). This is by far the most dramatic customisation, and I cannot thank Harris Cyclery enough for doing such an amazing job.



I wanted a coaster brake on the back wheel instead of the (hand-operated) drum brake that Pashley bicycles normally come with. Most people would have been glad to have the standard hand-operated brake option, but I wanted a coaster brake due to some problems with the nerves in my right hand. I can operate a hand-brake, but in stop-and-go traffic a coaster brake is more comfortable.



To accommodate this, the wheelbuilder at Harris Cyclery rebuilt the back wheel of the bicycle. This was done so impeccably, that it looks stock and absolutely flawless. I also asked Harris to set the gears lower, to make it easier to climb hills. They used a 23-tooth cog, which provided the lowest setting possible, given the enclosed chaincase. The 2 extra gears that came with the Nexus hub were pretty helpful in the hill-climbing aspect as well!



The front wheel retained the original Sturmey Archer hub dynamo/drum brake.



If you're confused, this means that I have a hand-operated front-wheel brake on the left handlebar, a 7-speed gear shifter on the right handlebar, and a coaster brake on the back-wheel that is operated with the feet by pedaling backwards.



Lights: We have added extra lights to supplement the standard lighting system.



Saddlebag: Not exactly a customisation, but the bag on the rear rack is a Carradice Barley. I absolutely love these remarkably roomy and attractive bags.



Initially, I had considered also replacing the basket and saddle, but on further testing decided to keep the originals. Please note that the 20" and 22.5" frames apparently come with a larger and more sturdy basket than the 17" frame.



III. IMPRESSIONS:



My first impressions of Eustacia can be summarised as "gorgeous, fits me perfectly and rolls like a dream... but unreasonably heavy". I had tested the Pashley Princess before purchase and had also tried several Dutch bikes -- so I thought I was prepared for the weight. But that was before I had to carry it up and down the porch stairs every time I wanted to ride it. I admit that during the first few days of ownership, I cursed and despaired, gave myself many bruises, and almost fell down the stairs a couple of times under Eustacia's weight. I was pretty upset about it and could not reconcile the fact that I had the most beautiful, elegant bike in the world and found it unmanageable.



Then, after a week, something magical happened: The bicycle miraculously lost weight! Well, either that, or I developed arm strength. Either way, carrying it up and down the porch stairs now takes only a couple of seconds and I take it in stride. Do I wish it were a lighter bicycle? I honestly cannot say for sure: Its weight also contributes to its stability, comfort on the road, reliability in traffic and tank-like indifference to pot-holes. (Edited to add: See also this post about speed.)



A summary of pros and cons:



Pros:

. stunning looks

. quality construction

. utilitarian add-ons

. luxurious accessories

. curved step-trough frame for easy on-off with skirts

. roomy and well-proportioned, with 3 frame sizes to choose from (I am 5'7", got a 20" frame, and can just reach the ground with my toes in the lowest saddle position).

. upright posture for relaxed riding, great views of surroundings, and visibility to traffic

. enclosed hub brakes make it weather resistant

. puncture-resistant tires are pretty much indestructible

. super stable

. handles extremely well in traffic

. sneers at pot-holes



Cons:

. heavy (specs state 45lb, but more like 50lb once you add accessories)

. not "agile" or sporty by any means; slow to accelerate

. upright posture restricts speed and uphill cycling

. saddle adjustment can be tricky with a "sliding off effect" unless perfectly tweaked

. if you are a private person who dislikes being approached by strangers, you might be overwhelmed with the attention this bike will get you. I get an average of 2-3 comments each time I take it out of the house.



IV. CONCLUSIONS:



The Pashley Princess Sovereign will give you elegant utility, with the bonus gift of increased upper body strength. As a town-and-country bike and a transport bike, it is a success. An agile, sporty bike it is not (and to be fair, does not claim to be). As with any bicycle, you can always customise components, which includes lowering the gears if you live in a hilly area. Enjoy the city and the meadows, and be prepared for lots of attention when people see this bicycle!
