  1. Having recently bought an '05 onza trials, I noticed the other day that
    the brake mounts don't appear to be in line with the rim edge, i
    presumed that it was designed to be used with Magura HS33s but i think
    if i fitted a pair they would only work on the tyre, which is no good.
    The lower of the two threaded bolt holes is about level with the rim,
    as far as i can remember the cylinder is equally placed between the two
    mounting holes on one of those brake cylinders, so it would miss by
    quite some way. Can anyone shed any light on this? Does it require
    different brakes, different mounting hardware, or have I somehow got a
    duff frame?

  2. Yeah it's pretty much centered.

  5. YIKES! I dont think there is a fix for that other than cutting off
    brazing on a new one and re powdercoating. Can you return/exchange it
    to the vendor?

    Is that a 20" or a 24"?

  6. It's a 20", I think it's going back to UDC, i just wanted to check on
    here first to make sure i wasn't being stupid. If mine's been
    incorrectly made then presumably there's a whole batch of them out
    there, check your Onzas people!

  7. Wow dave, I didn't even notice! Thats a very long way off, its too far
    up for even a 20" rim, so I can only assume that they used the 24"
    measurements or the 24" jig to locate the mounts, without realising
    that the frame was a 20". Return & replace the frame, Roger'll sort it
    out. Before you send it, make a measurement of bearing holder to mount
    distance, and we'll compare it to my onza 24" at christmas.

    Loose.

  8. Why do you want HS22's on a trials unicycle?

    I'll bet they measured the brake location for a 20" BMX wheel rather
    than the 19" trials wheel. A 19" trials rim is slightly smaller than a
    20" BMX rim and that distance appears to be about the same as your
    brake mounts are off-center.

  10. The mounts arent measured for a 24" frame, right now i am riding my
    trials with a 05 24"KH frame and the mounts are higher than that, the
    bottom one is even with the tire.

  11. Roger's reply to my email:

    "The brake mounts on the Onza are a mystery for several reasons.
    Firstly, As you can see they are not in the right place for the 19"
    rim,
    they appear to be designed to fit a 20" rim if fitted. Secondly, they

    were not specified with them at all because brakes are not used on
    trials unicycles..."

    Now i beg to differ on the subject of trials brakes, but as the advert
    on UDC's site does not imply in anyway that the Onza has brakes (either
    in the description or the photo) then I suppose I can't complain about
    the brakes that I have but which can't work.

    For trials brake uses search, there was a thread a a few weeks ago.
