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!Joseph

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? -

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.Ron

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

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. -

setup they came up with, and it just wasn't worth changing when the
weather forecast was for dry and balmy.And, BTW, Go Stuey!

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.

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

Does anyone have a photo of such a thing? I can't envision how that
would work.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.Ben

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.- Don Gillies

Who is confused? I didn't write the text above, merely quoted it.

you also have to be confident that you won't be making significant
changes to your saddle height :-)http://216.239.59.104/search?q=cache:sW2-MffTWToJ:www.campyoldy.co.uk/stocklist.htm+seatpost+drilled+for+brake&hl=en&ct=clnk&cd=15
