I have an '08 Cannondale Capo with Sugino 75 Cranks and BB and this is my main bike used for commuting about 20 miles a day. I'm curious as to how the 75 BB will hold up to an entire winter of riding through the rain/snow/salt/etc. I guess I don't mind tearing apart the BB after a few messy rides and repacking everything, but I was thinking about maybe switching to a sealed cartridge BB since it's an all-weather bike. At first I was thinking I'll just get a super cheap cartridge BB for the winter and then switch back to the 75bb in the spring, but I need to ride rain or shine so I started to think about a getting a really quality cartridge BB.

Curious if anyone has any thoughts on the matter and if you think cartridge is the way to go, any you would recommend? (I'm running formula hubs). Thanks so much for all your help!
