SRAM GXP Team Bottom Bracket (discontinued)

Over two years, I went through a surprising number of these bottom brackets on my cross-country bike. The durability of the bearings was never quite satisfactory. I was running a Truvativ Stylo crankset, and these bottom brackets inevitably developed play after a few months of riding. They were also prone to creaking if not thoroughly greased and tightened. On the bright side, I never had an issue with installation or removal. The cups spun in without any problems, and whenever I needed to re-grease or replace the cups I could back them out without undue effort. However, this doesn't change the fact that these bottom brackets didn't hold up well on my bike. Every one I bought was disappointing.

I've run this same BB on two different sets of Truvativ Descendant cranks. This BB came stock with the crankset and its worked great.  I haven't had to mess with them since the original install.  Sometimes the washer on the outside ends of the BB can slip off when installing, and its easy to loose if you not paying attention.
