• Er. WTF?

    My U brake arrived. But it is rendered utterly useless by the seat-tube, which prevents the arms from being pulled together. It's not even close to fitting.

    So what the hell model of brake am I supposed to be installing down there?

    Needs to be:

    • Centrepull
    • Boss-fitting
    • Boss bolts 75mm apart

    This diagram below seems to suggest that such a brake exists (Edit: and so does this thread on bikeforums). I have a nasty feeling that is may be exceptionally rare.
