    The new Ultegra calipers were designed to be mounted in a fork and frame drilled for a recessed bolt. The frame you are using is probably not designed for this type of bolt, it might have been designed for nutted bolts that are longer and go through the frame.

    To fix your problem we need pics, it may br possible to dril out the frame or change the calipers around to you can use them as nutted calipers.

    This is the difference between the two types, the nutted type is much longer.

    In addition to this, I would bet the Ultegra calipers you bought have much too short a reach for your frame. Older frames generally had longer reach brakes. Reach: http://www.sheldonbrown.com/calipers.html#reach

    Again, we need pictures to tell you if these brakes will even work or not.
    Why "derailer" is the correct way to spell the gear-change mechanism: sheldonbrown.com/derailer.html

    I drilled out the back of my peugeots brake mounts to fit the recessed kind. Not that difficult to do and it worked out just fine.

    It might, but who cares? If it works, ride it.

    drilling is the best option but not your only one. on many bikes you can install the front (long stud) brake on the back with the concave washers and nut from your old brakes. then mount the rear brake on the front using the recessed nut placed inside the fork crown/steerer or use a long recessed nut made for a carbon fork in the traditional manner.

    i have done all three of the above options with great success.


    due to the tight area behind the rear triangle, this is what i would do:
    use the front brake on the back with the concave washers and a nut

    drill the back of the fork out for a recessed nut and mount the rear brake on the fork with a long recessed nut. you may have to cut the nut to the "perfect" length.

    Unless it's a prized frame... such as a PX10, paramount or etc... and you have to do some "chopping" to get some stuff to be compatible..

    or stick the brakes you bought on fleabay and try get something for them and buy appropriate brakes for your frame
    Did you poop at that stop back there? I didn't pay $300 on brakes that save 150g to have you carrying around 600g of breakfast all day
