Record 10 Chain & Front Derailier Cage(7 posts)

Record 10 Chain & Front Derailier CageKen
Mar 27, 2001 7:12 PM
Put in my first 20 km on my new bike with Record 10. The Record 10 is a 53/39 with a 13/29. Whenever I shift into the 8th, 9th and 10th cog (29 teeth) the chain rubs against the inside of the front derailer cage making a rattling sound. Is this normal? Can it be adjusted so it doesn't happen?

The front derailluer on a Campy system is only semi-indexed, there are about 10 positions it can be in, so the derailleur can be trimmed. To eliminated the rubbing, just push the left thumb button down a click or two.

DO you know if this "progressive indexed" system applies to the Daytona 10speed group as weel as the record? Thanks for sharing your expertise.

It applies to all current Campy groups.

Thanks TJeanloz,

Your advise was spot on. Shifting is now rattle free. Yeah!!

readjust the limit screw....dave

The low limit screw (for the little chain ring) should be adjusted so that there is no rub in the lowest cog. Be sure that the cable tension is not too tight, or the derailleur will never hit the low limit screw. To be sure, loosen the cable a little, then retighten after setting the low limit screw. There should be very little or no slack in the cable, when shifted to the low limit.

The last click on the thumb lever should place the derailleur at the low limit.

I assume you aren't talking about chainrub when in the big chainring. If you are, then it's just a matter of clicking the thumb lever to trim the derailleur in a touch. You shouldn't be using the big ring and the 10th cog at all. Even the 9th sould be used sparingly with the big ring. If you're going to ride in a gear that low for long, shift to the little ring, and up to the 6th or 7th cog.

a little tweak on the limit screws should do it.
