Well it is finally time to replace the lead anchor BB on my '08 Monocog. Despite how cheap I would imagine the stock square taper BB is, this thing has done its job well. I have submerged my bike more times than I can remember and it just keeps going...but I think my abuse has finally caught up with me.
The shell is so corroded/rusted that I cannot make out the size and manufacturer of the BB. Am I correct in assuming it is a standard 68mm square taper BB? What would you guys/gals recommend as a replacement? I'm looking to drop some weight but I don't want to completely sacrifice durability.
My other question is rust. As stated before the bike has been through some water a few times. After each time I remove the seatpost, drain the frame, and leave it out for a few days for any residual to evaporate. Last time I had the BB out was maybe a year ago. Interior of the frame maybe had a little surface rust but nothing crazy. Today I took the BB out again and the rust is substantially worse. Hind sight I should have used Frame Saver when I first bought the bike. Is it too late to use a frame saver type product? I love this frame and want it to last...just hope I can do something to prevent future rot.
