    I doubt that the 1″ size had much significance in itself. In theory it should have been thicker to end with the same stiffness.

    Brake judder could have affected it though – more cycles and probably higher repetitive load

    Where did it snap?

    Overtightened stem? Or at the bottom bearing race? Or somewhere else?

    About 20mm above the crown race. I’ve got a pic but can’t post it from this machine.

    How much use has it had? I imagine being 1″, that its had some fair old hammer over a good few years?

    Broke me steerer on the crosser today and started to muse about the contributing factors.

    I wonder what difference it being 1″ rather than 1″1/8 made?

    The front end suffered from really bad brake judder. I wonder if this plus the above, plus aluminium steerer made any odds?

    My basic knowledge of materials science says the answer to both of these is a kind of qualified yes but I’m happy to be corrected.

    Any hoo the upshot is this.

    The fork is probably about 7 years old and it’s had a proper hammering in that time. It doesn’t owe me anything.

    7 years of brake juddering – most likely a simple fatigue fail.
