I have a steel bike with fenders, 32's with off road treads, and a rear rack that I use from November to early April. Cold weather ,for me, means I'm always taking things off and putting them on so I need a bag on a rack to put things in. As far as cleaning it, how is that even possible when it really hasn't been above freezing for 3 months A wipe of the chain once in a while and some lube, but no real cleaning. Can't bring it into the house unless I want to resume my single life (would rather not). Carbon bike comes off the trainer/clothes rack in a few weeks. Truth is I ride my Casserole at least half the time even when the weather is good as it just glides, and then I can delude myself into thinking that I may be approaching fast when I ride my Madone. Perception is everything........
