This to me is why no bike I own, and ride will ever have anything but a threaded BB. I suppose that could change if they invent something better but so far they have not at all. My shimano external BB have never worn out. I have over 50000 miles on my Habanero 6800 Shimano BB. Trek really messed up with this and really had they simply retain the original thread BSA the frames and bikes would still be super light. They saved nothing and cause riders a royal pain in the ass.

Sorry rant over
