  1. So I got myself a cheap BMX caliper break from the LBS, and it has long
    enough reach, but the bolt that attaches it to the frame isn't long
    enough to go all the way through the crown!!

    Now, I thought this was a standardized length, and the bike shop
    doesn't carry any longer ones...furthermore, I don't see any
    measurements on any online brakes I could order to make sure the bolt
    is long enough on those before ordering. Is this a common problem?

    I am using a standard Radial 360 frame.

  2. there's one bolt for the back brake and one for the front. front one's
    longer. maybe they gave you the back one instead of the front one, and
    said they didn't have any longer one's for the back brake.

  3. I'd try the local hardware store. Also, this type of brake appeals to
    me more the Magura. Could you post a bit more info about it, and
    whether a bolt from the hardware store would suffice. Did you have to
    drill a hole in the fork?

    You have to drill one hole in the crown. I got a tame engineer to do
    it for me. He machined a little round reinforcement plug to go into
    the bottom of the seat tube but that shouldn't actually be necessary.

    I've been playing with it on my 29er muni; it seems to work OK in the
    tests I've tried. I need to find some bigger hills to try using it on!

    Dave: Just a question. What use is a unicyle with no seat? And no
    pedals!
    Mark: To answer a question with a question: What use is a skateboard?
    Dave: Skateboards have wheels.
    Mark: My wheel has a wheel!

    Yes, you need the *front* bolt, which you should be able to get at your
    local LBS; if not, you can get it online for cheap.

    Okay...I'm not completely insane. This is exactly what I told the dude
    at the LBS..."this looks like a back brake, and I need a front brake."

    He politely explained to me that this one was "universal", which means
    one size fits all. I think it means one size fits none. However, the
    more frustrating thing is, I don't know if this "universal" size is
    standard, because none of the catalogs he looked through mentioned the
    length of this bolt, so I don't know when I'm ordering which ones will
    fit or not.

    I also tried the hardware store approach. You'd assume the bolt would
    be a standard bolt, but they found a way to thwart my plans. The bolt
    is threaded on both ends, and has a thingy pressed into the middle.

    And steveyo, 'these ' (http://tinyurl.com/2jjhdg)are the types of
    brakes I was looking at. The caliper brake must have a "reach" (bolt to
    brakepad) of about 85mm for it to work on an airfoil/Radial 360 combo.
    As to the drilling question, I was pleasantly surprised to find the
    Radial 360 frames (at least the US ones) come with the hole pre-drilled
    🙂

    So I guess what would be helpful for me now is links to caliper brakes
    that you guys have bought and that worked...

  7. uhh...kind of a bump.

    I saw 'these' (http://www.danscomp.com/484009.php?cat=PARTS) on Dan's
    Comp, and it says they come with -both- a front and back bolt, which
    leads me to believe that I should see if the LBS has the front -bolt-
    separately, or just get the Odyssey brake from Dans Comp.

    So what kinds have worked for you guys? I know people have done this
    successfully before...
