    Disc brake on a non-disc brake frame?

    Hello, I was wondering if it was possible to run a disc brake on a non-brake frame? If so what would I need, besides the obvious? Thank you for your time!

    Yes, it may be possible.

    They make frame adapters that may fit your bike.

    You would also need a disc compatible rear hub and possibly some adapter to fit the brake caliper to the frame adapter.

    Are the frame adapters pretty common? If so what are they called exactly?

    I haven't seen any adapters in person, but I do know two people locally who have converted steel frames to disc by just buying the mount and having it welded to the stay. You should also weld a brace into the stays to make an extra triangle back there and reinforce the tubing that way. One used a piece of brake rotor and the other used tubing...both are holding up just fine. Depends on the frame, but some steel frames use thinner tubing that isn't up to the stresses that discs will put on it....welding that reinforcement helps. If you have an aluminum frame, I'd just shop for a new frame instead.

    I wouldn't say common, I've only seen one person using one.

    Here is one, scroll down and it's on the far left.

    One company that sells them is called A2Z.......but again, it's dependent on your frame.
    Do you have a pic?

    On an older frame w/o disc brake mounts, I would just mount one on the front and use whatever you have now on the rear. Frame adapters and welding a mount are too much hassle for little benefit IMO.

    Brake Therapy used to make adapter. Not sure if they still do.

    Front brake only is fine

    Experienced riders know that the rear brake has a minimal benefit in terms o stopping power. All it does is lock up the rear wheel, which can be done effectively by a V brake.
    The difference in braking power and feel is something that you will adapt to quickly if you have skills and never if you don't.
    Good Luck.
    My goal is to get a new fork for my cross bike with disc mounts and a
    mechanical brake.

    Yeah but having a disc in the rear means the added benefits of stopping in the rain and mud and not having to worry as much about a true rim.

    How about some pertinent information...what kind of frame (make, model, year) is it? I ask because Trek/Gary Fisher/Klein frames from the early to mid 00's used an adapter to run disc brakes on many of their frames.

    I am not sure what year it's from its an older VooDoo full suspension frame. I know that disc brakes aren't necessarily better than v-brakes, but I already have the items necessary to convert it over. If needed I can have pictures up in a few days.

    Hey ericknguyen95128,

    You may want to check this thread out: Rear disk brake adapter. There is some pretty good info for running rear disc brakes on a frame that doesn't have mounts. Also I've used the A2Z Adapter mentioned above and it worked but it has some limitations (see my posts in the above mentioned thread).

    Disc Brakes are necessarily better than v-brakes. V-brakes are a Hugo and Disc brakes are the Ferrari. There is no debate. It is not even close. The weight may even be less on some disc brakes. This is the reason that you are changing your brakes.
    Cheers!
