• bb86 on Giant's is annoying as you're essentially limited to GXP and Shimano cranks.

    Not really an annoyance TBH, especially with Shimano chainset.

  • True, I was mainly referring to that being what you're limited to: no 30mm spindles unless you want complex, short life bearings and the market is generally moving towards 30mm. BB30 can do any crank with good size bearings.

    But I agree with eyebrows, bb30 for it's original intended purpose with c-clips and pressing them is generally a bit shit

  • At the moment, the only groupset manufacturer that are making 30mm spindles are SRAM.

    At the moments, quite a fair number of aftermarket manufacturer are making 30mm spindles.

    I don't know why but BB86/90 were a piece of piss in comparison to BB30, in term of reliability.

  • I was about to argue that the 24mm spindles mean you can used it on threaded bottom bracket, until I realised this exist.
