    Disc Tab Jig

    I was wondering if anyone could tell me who makes the best and most affordable disc brake tab mounting jig, or is it better just to make it myself. I haven't put disc tabs on my frames before and I want to get this right the first time. I have never even run disc brakes. Does any part of the disc brake setup float or is it all fixed inline parallel to the wheel?

    You can get it right using a rotor and a caliper, or using a normal metal worker's tack measure tack measure approach. However, the Anvilbikes.com looks nice, and also looks home makeable if one were not concerned with looks. Use the standard metal workers approach of tack, measure, grind, etc... and when it comes out perfect you are ready to go without having touched your sainted frame.

    I have the Anvil Phrunt Shui for disc mounts on forks. Works exactly as described, as does most of Don's stuff. I can only assume the frame disc mount jig works just as well. For the rear I use the jig offered from Nova. Again, works exactly as you would expect.

    It ain't exactly rocket science and you could easily get away with mounting a hub with a rotor bolted to it. Then take an Avid road disc caliper (assuming this is for a road or cross bike this is the only disc rotor that will work) and dial in the pads until the caliper is locked down on the rotor. Bolt the disc mount to the caliper and keep shaping teh disc tabs until you get a good fit to the seat (or chain) stay. The only downside is that you will once and forever relegate that hub, rotor, and caliper to "shop tool" status.

    The dropouts that are fabricated with disc tabs already on them, do those work with only certain brake set ups. Now I am looking at Paragon sliding dropouts for this frame. Are there many different disc brake set-ups?

    Brake tab spacing is standard.

    I also want to add discs and calipers to an old bike. The type of jig used by anvil bikeworks looks simple enough to make but what are the required ISO dimensions? (are they in ISO 6697?)

    I found some nice PDF drawings at Hayes website.
