• Shimano road bottom brackets.

    The old larger silver ones were fit and forget, but I think I’m on my 3rd BBR-60 (the narrower, black, ultegra level one) in as many years.

    Rotor 3d24 and torquing pre load with a torque wrench (1.5nm or whatever) so reasonably confident that I’m not too cack-handed. The bike gets ridden in every weather mind, and I do no maintenance to the bb.

    Just me? Unlucky and try again? Or are these now throw-away wearable parts rather than things you’d expect a decade out of.

  • Has your frame been faced?

    Can't say as I've noticed the smaller ones being less rel,iable on either road or mtb cranks but I always face the frame as I have the tool.

  • Yep, faced last time or time before.

    Googling doesn’t suggest that they’re less reliable either so maybe I’ve just been unlucky
