comment Snow Tire Wraps for Bicycles
I saw a picture of some once, about 20 years ago.

comment derailleur P-screw/B-screw does absolutely nothing
What did you open up? What did you disassemble?

(If you removed/disassembled the cluster, make sure you didn't do something there to throw the cluster in or out relative to where it was originally.)

That screw has essentially nothing to do with making the derailer center over the cogs -- it's purely to adjust tension in the chain, and, to a degree, adjust how far the jockey wheel stands away from the cog.

(Ignoring the highest and lowest cogs, does one click of the lever move the derailer exactly one cog?)

Are you sure you have the right derailer and lever set for your rear cluster?

comment How to remove dried vulcaniser from cotton clothes?
Regular petroleum solvents are highly unlikely to work on the stuff. They'll just turn it gummy.

comment Does a hybrid pannier / backpack exist?
Or a trailer. You could fit a full sized backpack in a Bob with ease.

comment How can I bike in Winnipeg, Manitoba, Canada?
Yeah, the electrical sole liners are probably the thinnest option. At one time I was considering making some, but I never got around to it.

comment Does a hybrid pannier / backpack exist?
I suspect the only way to achieve something remotely practical (without regard to cost) would be to have two panniers that would somehow be joined into a single backpack.

I have used the oxidative heating packets (the small ones for your toes) before and they work pretty well. The main problem is that they (and the other schemes) take up space, and you really don't want your shoes any tighter.

But the setup is highly likely to have serious ground clearance and heel clearance problems, not to mention being badly unbalanced.

I suspect you're trying to optimize the wrong component. You can buy an inexpensive frameless rucksack that will be better than any pannier-converted-to-backpack, and Campmor lists an external frame unit for $39.95. The frameless unit could be folded up and stuffed in a pannier (or strapped on top) if need be.

And note that your typical full-sized pannier has about half the volume of full-sized standard backpack.

comment Does a hybrid pannier / backpack exist?
There are (or at least used to be) panniers that were designed to convert to a backpack while off the bike. But generally they were intended for commuter/day use, not touring.

This is info I read via the icebike.org site. But that was probably 10 years ago.

comment Do I need to plug internal cable routing ports?
@Vorac - Don't seal the frame up tight. There need to be vent holes, at least, and in some cases the cable holes are serving this purpose. Try to "seal" to prevent water entry but not totally block airflow, especially with the lower port.

The two biggest hazards (other than falls and collisions with motor vehicles) are frostbite and airway injury. I've experienced airway injury cycling in temps around zero F (foolishly cycling hard when I could have taken it easy), and it's bound to be a much more difficult problem at -50 where even a single deep unprotected breath can be problematic.

In extremely cold temps the tires get "interesting". The rubber is so stiff that tubes are hardly needed, and sometimes so stiff that the tire separates from the rim and the rim spins inside the tire.
