Thanks for the advice everyone! Another question. Brakes. Should I upgrade to disc brakes from v-brakes? I am almost set on doing this, but cannot totally decide. If so, are there any true advantages to having hydraulic discs brakes versus mechanical discs brakes? I hear the hydraulic disc brakes don't work so well in the cold due to component contraction. Does anyone have experience with either kind of disc brakes in really cold weather? Thanks in advance!
