Well, after about 6 solid races, 4 of which were extremely muddy and wet, my MegaExo BB went out (drive side). I pulled the BB out and pulled the bearing cover off and found a cartridge full of mud, water, and sand. Seals must be crap on these FSAs. I don't think I want to bother with attempting to clean and re-grease the bearing cartridge only to be doing this in a couple of weeks again...
Any recommendations for an affordable--sub $100--external BB that has decent seals and take the rigors of cross? I'm thinking of getting the Ultegra 6700 BB; any experience with these?
BTW, I roll with a FSA Gossamer crankset.
