I'd like to replace the crank on my bike. It's a Schwinn RS 5.0. It is an ISIS style. Can I just go on ebay and buy a 175mm Triagra crank and BB? D I have to know anything about the size of the BB. Current system is a Prowheel Ounce.
I partially stripped out thee threads on my right side crank handle. (I had forgotten to finish tightening it after assembling the bike and sprinted up a hill. Lucky it didn't pop off while navigating traffic, at speed.) It sucks more because I really wanted to wait until the next payday and upgrade the rear derailleur to a Shimano Tiagra. On the bright side, this is the perfect excuse to purchase an upgraded crank that my wife cannot object to.
