    Convert BB7 to BB7 Road

    Cross-posting this from the brake forum as I figured it might get a bit more attention here.

    I'm planning a CX disc build and have a pair of BB7 MTB calipers I'd like to use. Any reason I couldnt use THIS to change the leverage ratio to work with road levers?

    I looked at doing the same myself, I cannot verify it works though. Would be interested in knowing myself.

    Seems like it should work, one disadvantage would be no barrel adjuster at the caliper.

    Before you start buying stuff.....I suggest you try the mtb brakes with the road levers.
    I rented a tandem that had the mtb BB7's and they worked great....
    The shop mechanic claimed this was the hot set up.....and quite a few tandem folks agree.

    I'd say give it a shot with the road levers unmodified, and then try the caliper conversion...it can't be much money.

    I assume you planning on shifting with the levers too....if not, just get some long pull drop levers from Tektro.

    Will not work. The only difference between the road and mtb arm is the color.

    The internals are where they differ.

    I have a brand new set of BB7 roads I would be willing to swap for BB7 mountains, as long as the mountain one's are in great shape with new pads. Just the caliper gets swapped, we each keep our own adapters. PM if you are interested.

    Did you have any luck with the arms?? I can't tell from the Avid web page if the length is different.

    Although it may be due to differences in anodizing, the referenced catalog lists different part numbers for the Torque Arm kit for road and mtb as well as different part numbers for the BB7 internals kit. My take is that the torque arms are the same length just the road is anodized silver and mtb is a darker grey but you definitely need the correct BB7 internals kit parts.

    Could you use Travel Agents to make this work?

    Theoretically, but IME Travel Agents are too fussy and come out of adjustment too easily. Their cost is as much as a pair of long pull levers and nearly as much as discounted BB7 Road calipers.

    I have a set of the long pull Tektro levers on BB7 mtn calipers. Works pretty well.

    If you already have a favorite set of rotors, you might want to consider Shimano CX75, the stock calipers are a lot less $$ than the Avids and even with stock hardware, ~10-grams lighter than the BB7 Road SL with Ti hardware.

    Needing tools to adjust the pads of the Shimano is a deal killer for me.

    I have rival shifters and bb7 mtb going to try this 1st and see how i go, but does anyone have an ideas how much the replacement internals are?

    In the end for me here in australia it might just be easier to but new calipers
    29er you just know when ur ready!!!!
