    ex7 bottom bracket

    What are all the compatible BBs for this bike. It's confusing to me, especially since I don't do my own work . Thx

    I am not sure which type they used on it that year. It will either be a Press fit in which case your trek dealer can order them and advise you on compatible cranks etc. I have a friend with a 2013 EX6 that has a threaded BB, and if that is the case your options are unlimited pretty much.

    Can you take some pictures for us?

    I just did some looking around and it appears that bike came with the press fit BB. Basically you can run Shimano 24mm spindle cranks which is pretty much all of them, SRAM GXP cranks and some others with a different bearing set. However any 30mm spindle cranks are not going to work. You can order the press fit bearings from an online place, or go to your Trek dealer and they can set you up. Are you trying to change cranks, or just the BB?
