|Anybody have experience tuning the new record triple? My LBC tuner can't get the correct chain length so that all 10 rear gears work with all three chain rings without some rubbing on the rear derailleur. Anybody else having problems or a solution? ( forgive me because I am not a mechanic, and I am loosely translating what my bike mechanic told me.)|

|What size is your rear cassette, 11-21 or 13-29, or something in between. Also do you have a long or a med cage rear derailleur.|

|the cassette is 12-25, and I am not sure about the derailleur cage...I will try to find out.|

|I got it to work with the triple and 11-23 cogset. I think you focus on the small/small combination, and make the chain as long as possible without the rear derailleur having problems.
If you must err either way, I'd err on the side of too long vs. too short. Too short can really foul things up if you inadvertantly shift into the large/large combo.
|there will probably be some rub||ColnagoFE|

|mostly in the redundant gear ranges though. are you trying to do big/big, small/small combos?|

|...but why would you even be trying to run the samll/small. In the granny ring,I would probably never want to use more than the 5 largest cogs anyway. Size the chain to accomodate the big/big,just in case, and quit friggin with it.|

|The instructions that come with the Campy der's are incorrect.
When using the med and long cage der, you must shorten your chain a couple of links (from what the book says) to keep the upper jockey wheel from rubbing on the cassette cogs. You can also adjust the "B" screw which might help a little. I KNOW it's not called a B screw with these Der's but it does a similar sort of thing.
Someone mentioned that the 2002 der's don't have the B screw any more. ????? Don't know, but it seems real odd if they don't.
|no B screws on Record derailleurs now nm||DougSloan|

|Doug, it's not often that you're wrong, but this time, you are. There is still a b-tension screw, Campy just moved it to a really sneaky place for 2001 and beyond. It's hard to describe where it is, except that it's on the underside of the derailleur, near the top jockey wheel. The new design (allegedly) allows for more adjustability of B-tension.|

|I'm not as smart as I sound- it took us 3 months of installing them before we found the screw.|

|You mean they hid that sucker from me? Damn Italians.

|Sometimes it actually pays to read the info that comes with the parts, I hate to admit it too. Heh-heh|

|I preach that, too. But when every other derailleur I've seen in my live had that screw sticking right out there for everyone to see, you just don't even think about looking elsewhere. Plus, I never really knew what to call that screw, anyway.|
|Yes B screws on Record derailleurs sort of||mhinman|

|There is a screw that tightens the pulley cage spring which causes the jockey wheel to put closer to the cassette, acomplishing the same thing as a B screw.|
|My LBS guy finally found it as well. thanks for the input.||DrSchu|
