I lost the directions. How do I determine where to position the front deraileur (up and down) on the seat post?

Thank you in advance,

Between the bottom arc of the cage and the outer edge of the big ring.

The historical Shimano recommendation has be 1 mm. That's 1/25 of an inch. For all practical purposes, that means As Close As Possible. Set it so the cage just clears the teeth of the large chain ring.

You what about 1 to 3mm of clearance from the tallest tooth profile. 1mm is fine for a very stiff crank and bottom bracket shell. If you can flex any of the above you will need more clearance so you don't rub the chainring on the derailleur.

Awesome. Thanks everybody. I like the shot with the penny.

It should say on the instruction sheet, which you REALLY should read. Bicycle maintainance 101 is as easy as reading the instructions... please do... I'm afraid for those parts.

Having spent too many hours setting up a Record Compact frt I can help you out a lot.

1. No cables attached, set the FD as low as possible so you can still push it up and down, make sure to rotate the cranks incase you have a wayward tooth on the rings.

2. Trim the high and low limits so it is JUST low enough not to hit the chain in the easiest gear, and trim the top out so you don't throw your chain.

3. When you connect the cable a fourth hand from park is handy but pre load the FD some or use your barrel adjusters to allow you to add tension to the cable. Campy 101, apparently super tension is needed for Campy stuff :). You want the first push of the paddle to initiate movement.

4. Hopefully enjoy your super fun new gear, it's good stuff!

Campagnolo, like most manufacturers, have instructions on their website. Typical case of RTFM AFAIC.

Get thee to the Park Tools website. Their method for derailleur (front or rear) setup is uber clear and works like a charm, whether you've got Shimano kit or Camagnolo kit. FWIW, pretty much all of their "how to's" are useful.

Go Hoosiers man! :) Best of luck with the FD, I know it takes some time, the tension is what made the biggest difference for me!
