Getting out the drill

    I know I've asked this question in other places before, so it is
    probably me just procrastinating about the bush. I have an old(ish)
    Raleigh Pulsar that I'm getting into better working order as a project
    to have a road bike. Most of it is done now, apart from the new brakes.
    I'm fitting Shimano Sora new cantis on an old frame, so instead of
    having the long fitting bolts to fit through the brake bridge or front
    forks, you have a shorter bolt and a recessed "sleeve" nut. The holes
    in the old bike aren't big enough for the recessed nut, so I have to
    enlarge them. I have heard from people who've done this exact same
    thing with old Peugeot bikes, and I think Sheldon describes it on his
    site too. I just wondered if anyone here had done something similar and
    had any pointers as to obvious or not so obvious pitfalls.

    Can't help you with your question, but it's calipers, not cantis.

    Are they long-reach sora (aka standard reach)? I thought that frame would
    need those rather than the more common short-reach ones.

    You could get a set of these which wouldn't require any drilling

    Doh - yes of course it is. I did know that (after all I managed to buy
    the right ones) but twice since I've put "cantis" into Google when
    looking for advice instead of calipers. Double DOH!
    Not sure <rummages around for brakes, frame and tape measure>... I'll
    get back to you on that one!

    I did it to my old peugeot. I cannot remember why but it must have been
    when I replaced the centre pull brakes with some that were new old stock
    from a jumble sale.
    I just got a bit of the right size( don't know), tested it on a spare
    bit of metal, then did it by eye. It worked fine. I am not someone whose
    technical skills you should seek to emulate, however.
