Hi all,

I have built loads of Road bikes but this is my first Cross bike....

I am fitting the new 2015 Campag Chorus groupset which includes the S2 front derailleur.

Can someone tell me what I need, some kind of 'pulley', to make this work as the frame has top routed cables.

Thanks in advance,

you need a pulley which sits behind the seat tube. If the frame has a boss, you just screw one on. Or there is this with a clamp
There's sometimes a buggy.
How many drivers does a buggy have?


So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.

There is a much better solution than that, if somewhat heretical. Fit a Shimano CX70 top pull front mech - no need for clunky pulleys that will only collect mud. I have a CX70 mech on an otherwise Campag Athena equipped CX frame and it works excellently. It's quite cheap too.
Seriously, this is the way to do it.

Top pull is the way to go in cross.

+1 with what @Miller said.

Or get an umlenker from: ... store.html

problem solvers pulley will work if your frame will accept it. Otherwise as Miller states above just get a shimano CX70. Should be good to go after a bit of fiddling.

The CX70 works very easily with the Campag ergo and not difficult to set up.

The umlenker is a nice idea but my experience with one was not good. It put a lot of leverage on a little alloy tab on the Campag mech that fairly quickly broke off.

Or a single chain ring set up?
(Dare I propose this...)
