• grinding material off the axle to start vertical play like the Hollowtechs did.

    That’s interesting, I hadn’t heard of that mode of failure before with hollowtechs.

  • I've seen it, but only where the bb has been so neglected that the bearing has seized and the crank spindle starts to spin within the bearing.

  • Same; this happened to my partner’s old bike that hadn’t been looked at for years. BB and cranks trashed.
