Winter cycling, bike sizing and cycling calculators

Icebike started in 1998, when a group of riders on a winter cycling mailing list began writing down what actually works on snow and ice. We still do that. Find the right frame size, work out your gearing and speed, fix the problem that stopped your ride, and keep riding when the roads freeze.
