The bearings in my Caad 10 are already dead. They lasted about two months, and maybe 30 hours of riding. I've been running Cannondales with BB30 BBs for 10 years now, and this is the first time I am actually having to replace the BB bearings in one of my frames. I ran the same set of BB bearings on my System Six for eight years. (I'd still be running them had the frame not been broken when I was hit by a car.)

I think the bearings in the Caad 10 are ceramic. I think I am going to try Wheels Manufacturing's Angular Contact Bearings. They cost about the same as regular Abec 5 steel bearings.

Also, I cracked another Sram RD derailleur pulley. I'm not sure how I tear through those things so quickly. I think I might try one of the Aluminum options offered by Fairwheel Bikes.
