Has anyone tried installing Shimano 6800 bottom brackets with FSA SLK Light tandem cranksets? Our FSA brackets appear to be shot after relatively few miles, and our experience with Shimano bottom brackets has been much better (over 30,000 kilometers on a pair of Octolink BBs on one of our earlier tandems). Although I really like our Chris King headsets and hubs, I am not sure I want to spend the extra money on the BBs. Any advice would be appreciated.

Thanks

Joe
