• Just received a BBB BTL-38 to go in my kit bag in case I need to do anything to the lock ring on race days. Nice deep socket and a ½" square drive so it should work with pretty much any hub.

  • Got this, to replace a Park Tool BBT-9, but it doesn't fit either of my lockrings.

    Fits UT cups ok and the Park Tool fits the lockrings.

    PT ID is 45.75mm, BBB ID is 43.75mm.

    Presumably yours fits ok and I've just got a duff one?

    No, I've been meaning to point this out, the BBB tool is very mean on the bore and doesn't fit the lock rings.
