Thanks for the beta, everybody. I've been looking forward to commuting this winter, probably because after a few years of ski bumming I'm going to go crazy if I don't have something to do outside. Plus I've got a bin full of bullet-proof alpine gear that's just begging to get abused.
Nice to hear that track bikes can hack it.
I'll have to get some of this framesaver stuff, huh. And a fender. And a non-Brooks saddle.
