Good to know.BB90 is a press fit system that uses the bearings you'd normally see in Shimano or SRAM, or Campy bottom bracket cups. It works w/ 24mm axles, so no BB/PF30 cranks. I've been working on them and have owned them for years. No problems if they're installed correctly. If they're not, and the shell is slightly loose there is always the 'V2' bearing available that is .1mm oversize. I'd love it if manufacturers went back to threaded shells, but the Trek BB90 works fine in my opinion.
Thanks, I was wondering about SRAM cranks.I owned a Scott with the same system and echo everything CX said. If you want Shimano or Sram cranks it's fine and lighter than BSA. The only downside is you can't use most 30mm axle cranks and the ones you can use (Lightning on my bike) have tiny bearings that wear out quickly. This isn't too much of a concern though since if your priority is performance the Sram Red GXP crank is pretty light and stiff.
I've posted in the Trek forum with no response. Since Trek is having a sale, with some very attractive pricing, I am considering an Emonda SL and would like to hear about BB problems in the Emonda SL frame, if any?
Thanks in advance for your help.
Not uncommon with recent Trek OCLV frames. Good luck with the warranty.My 2016 Emonda SL6 with approx. 4500 miles (i'm 6' x 180lbs) has developed a problem and I think Trek has agreed to warranty it, although I don't have a new frame in hand yet. The problem is a small crack growing around the drive side of the BB.
