Iditerod dog sled mushers race and train outdoors all winter, so why can’t we bike longer? They pay close attention to details of clothing, wicking, and stay dry. I have biked 12 months for years in Chicago, but often get cold after an hour, so ask advice to stay out longer, as it has been 40 below zero Fahrenheit with wind chill this December. Still in Fairbanks, I dog sledded in 50 below (without adding wind) all day and slept outdoors at night. How improve while holding weight to a minimum for winter biking:
1) Most neoprene booties have large holes on the bottom and leak air. Any way to plug them? The Perlizumi Typhoon booties are terribly heavy and have a hole in the heel; my plain Spokes neoprene booties are about the same thickness as the Typhoons but warmer and no heel hole. Still cold after an hour.
2) Pedals with metal clips conduct heat more than carbon fiber. Look makes mainly carbon pedals but their cleats are large, requiring a larger hole than my summer Ritchey Road Logic cleats (steel). Advice?
3) I love my Sidi Silver Shadow mesh shoes but they leak air and permit only thin socks. I am ready to buy new shoes a size larger but welcome advice here in particular. Does any shoe have a sole that conducts heat less than the hard plastic on the Sidis? Dog sledders use thick sole liners inside boots made in Canada that make a huge difference; are there any light ones for biking?
4) Cuffs running from tops of mittens up to the elbow keep the wrist area warm, which is key to hand warmth. I have good cuffs on Austrian cross-country ski gloves but not on mittens. Does anyone separate make cuffs?
5) Glasses with metal rims make ears cold; plastic is better. Pretty good are my Bolle Equalizer amber ski goggles, made to hold prescription glasses underneath them. But when I slow down, the glasses fog up.
6) Balaclava by ProMax is pretty good but tight when new; older ones stretch but let in air. Silk is too tight on glasses and ears. A ski version has a huge Polartek turtleneck that works well.
7) Chamois crèmes I use normally are wet and get cold in an hour.. Some are more waxy (Udder Balm in NH green can), but does anyone have a more dry but slippery lubricant? There are lots of graphite lubes for steel bearings but do any work on our bearings and skin?
8) In a December Super Cup cyclocross here, I nearly froze my hands and feet in a 30 minute warm up, but was comfy during the race. I could warm up indoors but would prefer not to.
9) I have several levels of clothing that I shift as the temp rises or falls and am generally comfortable everywhere on my body except feet, hands, and sometimes face down to 40 below for up to an hour. But after an hour I get cold in the extremities.
10) The aluminum Deda handlebar and Shimano brake handles have metal exposed that I tape over with a two layers of cotton bike tape; any good ideas on low-conductivity tape could be a simple way to make a big difference. The new Perlizumi greptile seems pretty good on most of the bar. Is there better?
11) Water does not freeze in a thermos bottle, but how adapt/protect the thin tube from a Cambelback-type backpack water bottle so it does not freeze?
Advice on any of these points is most welcome!
