    Whilst trying to find the source of an irritating click saw this on the non drive side of the bb (bb30 press fit). First time I’ve had the cranks out on the bike. Had it from New, now approx 1k miles and first experience of this type of bb so unsure if it’s damaged or meant to be like that. Bearings are fine, no play etc. And bb seated properly. Can’t tell if it’s a washer or part of the bearing but it is seated firmly in front of the bearing and behind the main rubber washer next to the crank when attached. Any thoughts?

    It will be the retaining
    It will be the retaining circlip for the bearing, it will have a slot to allow it to be removed. Clicking and creaking press fit bearing are not uncommon. You may have success removing the bearings from the frame, clean all surfaces and re grease absolutely everything. I mean all surfaces which touch another.

    My own experience was it would clear my clicking noises for a few hundred miles then they would return

    I ended up installing sram cups which take threaded bearings. Problems all gone now. The look isnt quite as sleek, but when bearings go, undo, throw away and install new without worrying about creaking, which is bloody annoying.

    I would say that is one of the bearing seals that has been damaged, it’ll officially need new bearings, however i would be tempted to just ride until it fully dies…
    Though I don’t really understand how that would make it click :/
