BB needs replacing every 6 months. Why and how to avoid?

samfailed

Just found the Shimano Press-Fit BB on my Giant Defy Advanced 2 2018 has developed a fair amount of play in it again. This seems to happen every 6 months and every time the local LBS replaces it. Is there something I can do to stop this constantly happening?

One a side note, is it safe to ride a 114 mile epic on or is that a big no no?

How are you cleaning your bike, and what sorts of conditions are you normally / mostly riding in?

How are you establishing that it has 'play' - and have you ruled out the obvious like loose crank arms?

BB86 is usually problem free, and one of the better press fit standards..

I've got the defy adv Pro 2016 model and after all this time and a lot of miles it's still on the original BB. I'd be double checking for other issues just in case they cause the play / movement.

no idea if its cool to ride on as we can't see it.

perhaps your lbs is taking you for a ride/not very good as everyone on here says those BBs are fine.

Hi, I've got BB86 and only replaced it once in 17k, so every 6 months sounds unusual. could be a installation problem or a frame problem, Id get the next change at a different bike shop and see how you go from there!
