    rear disc brakes on old 94 Marin ?

    This bike originally has V-brakes like many bikes of this time. Is there a way i can make it so i can somehow install disc brakes on the rear? i am planning on using some Hayes Stroker rydes that came with another bike i own. I have included a couple of pictures in case they are of some help. Thanks in advance

    Hey,
    I just did this over the summer when I turned my first mountain bike into my first single speed. A Green 1995 Cannondale M400. Ordered the bracket from novacycles.com. I think it was only $6-$7. My Bro-in-law tigged it to the aluminum frame. Added BB7's and SD7 levers, the whole set-up works great. I stripped the frame down with aircraft stripper to bare aluminum and had it powder-coated clear. New bars, stem, seat post, seat, crank, pedals and some cheap vuelta wheels. It's now moved down to the coffee gettin'-dog walkin' bike since I discovered 29'ers. Still love riding it, more now than when it was new

    Since the frame is steel, it can easily be tig welded or brazed (preferably) with a disc mount. I would also recommend a support strut since the seat stays were never designed for the stress a disc brake will produce.


    The pictures above concern me...no strut and 6061 needs to be heat treated after welding to maintain strength, otherwise that area is a weak spot and likely will fail.

    I thought about the strut..but then, it's kind of exciting to think that the next time I take my strut free, weakened triangle 6061 bike out to walk my dog..it could be my last...

    Thanks for the replies you 2. Very interesting set ups. I was thinking of having welds done on the bike. It is tange chromoly steel. Is there any special step to welding this type of steel?
