  1. Not sure that I like the idea of a hole through my stem, particularly
    not for Paris-Roubaix!

    Why would they do that? Sacrifice stem integrity so you can use canti
    brakes? Doesn't seem like a wise trade-off to me. In Paris-Roubaix,
    the only thing you need good brakes for is to avoid crashes from
    people who's stems broke off on the pave!

    Seems like it might be a better call on a muddy Roubaix, it was very
    dry this year, seems extra strange.
    \
    Surely someone still makes an old skool stem with a properly
    integrated hole?

    Where else ya gonna put the cable stop? Actually, not that big of a
    deal..teeny hole, won't make the stem break. I have done it a few
    times. Better idea is a brake hole mounbted cable stop like Cannondale
    and Redline have/had. Bigger question is why Cantis? Don't the
    standard pave tubies fit?

    Cyclocross guys have been doing this forever and I have never heard of an actual
    failure. Hell, a lot have drilled the seatpost for a similar arrangement in
    back. That seems sketchy to me, but the drilled stem has never been a problem
    that anyone has ever actually reported. Lots of theorizing, no actual failures.

    Maybe, but if I ever got to ride in Paris-Roubaix, that wouldn't be
    the day to try to disprove the theory.

    The big manufacturers stopped supporting cantis when V-brakes took off,
    so you have to resort to this kind of thing now. Even if the tyres
    fitted into conventional dual-pivot calipers, the essential moving parts
    of cantis aren't directly in the firing line of mud, and presumably
    cause less trouble. They must have some advantages, since I doubt the
    teams are sponsored to use such old-skool equipment.

    Maybe they just built the bikes up during the winter and this was the
    setup they came up with, and it just wasn't worth changing when the
    weather forecast was for dry and balmy.

    Hey guys, it's 2007. Real cross bikes now use a bolt-on hanger at the
    crown. Simple, cheap, stiff, clean lines.

    Although I have built bikes to use a drilled stem (& post!) I wouldn't
    now - not worth the risk when bolt-on hangers are available.

    I have seen Pivo, 3ttt and Cinelli stems crack from a drilled brake hole.

    Similar to this?

    With a low stem I guess the headset/steerer tube ones don't work well?

    Like the stem. You would drill a ~5mm hole at the front of
    the seatpost that the housing fits into, and a small
    hole at the back for the cable to exit from. The cable
    runs down to the straddle. I would not do such a thing
    myself. I prefer a rear canti hanger that is part of the
    frame; since my cross bike doesn't have that, I have one
    of those little cable stops that hangs on the seat binder
    bolt. One might also be able to buy a cable stop that
    clamps onto the seatpost.

    Regarding the drilled stem, lots of MTBs used to have these.
    However, those stems usually had extensions of either solid
    aluminum or tubular steel. It seems a little sketchy to
    drill a modern lightweight hollow aluminum stem. In the
    pro Paris-Roubaix case, it is something that will be ridden
    hard for six hours and then taken off for good, so it's
    probably not a big risk. Those fork crown stops are nicer
    if they fit. What the world really needs is for someone
    to make nice stems-with-a-pulley, like the ones that
    Salsa did.

    I still don't get it -- it seems that the cable would be making a

    Could you point me to any photos of this set-up?

    I think you are confused, my understanding is that this was done
    mainly with sidepull brakes, in which case there is cable housing
    going all the way through the seatpost so that there is no wear to the
    drilled holes.

    I suppose you could do this with centerpulls if you added cable
    housing through the seatpost and a ferrule glued onto the end of the
    cabling - ending just on the backside of the seatpost, but I have
    neither seen nor head of that being done.

    You have to drill the holes at the appropriate angle to avoid this;
    you also have to be confident that you won't be making significant
    changes to your saddle height :-)
