We just got a decent amount of snow and now there's salt out, so I think it's time to put the bike away for the winter. I've been fantasizing recently about doing a winter / crappy weather build out of a mountain bike, with big tires, fenders, a single chainring and an internally geared hub. I was checking out the DBR Axis TT because it's titanium, but I don't know if I can justify the cost of that for a bike that's going to be abused. I do have an aluminum Cannondale Trail SL4 laying around that I almost never ride though... Maybe I could try to find a rigid fork for it so the suspension doesn't get ruined by salt.
There's a lot on the menu for winter maintenance including replacing the disc brake rotor, chain, cassette, and possibly converting to bullhorns on the Surly, then a BB overhaul

and shifter cables / housing on the vintage Motobecane.
