Shimano had a bike with their original Dura Ace groupset on it at a recent Interbike show -and from 20 feet away, it was hard to tell it wasn't Campagnolo stuff.<br /> Larry and Heatherhttps://www.blogger.com/profile/16346445393389942837noreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-41260051906754347692012-06-18T17:43:38.024+10:002012-06-18T17:43:38.024+10:00Thanks Wingnut!!

Or the ratio for the Athena?<br />That might be (part of) an answer.<br /><br />I haven't got all the parts yet, but I will certainly give it a try and let you know!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-80962565513253746922012-06-18T05:51:20.976+10:002012-06-18T05:51:20.976+10:00Hi GRMA. Matching Campagnolo's shifting compon...Hi GRMA. Matching Campagnolo's shifting components between these two eras is difficult. When Campagnolo abandoned Syncro and changed to index-only, 8spd, and cassette hubs they also changed and standardised the geometry of all their RD. The idea, à la the Japanese systems, was to fully integrate shifting and drivetrain components which is the only way that accurate indexing will work. This was a major departure for Campagnolo and marked the end of components designed (=compromised) to maintain backward compatibility. In this sense the shift ratio almost certainly changed - ie using the cable adjuster in your situation won't improve indexing but changing cassette spacers or cable line may help. I do recall an aftermarket part (I'm not sure if was made by Campagnolo) that allowed these levers to index 7spd but I'm not sure how well (or whether) it worked with screw-on freewheels or with Shimano's 7spd cassettes. But, if you already have the components, try them together and let us know how you go!wingnuthttps://www.blogger.com/profile/11016671831457597440noreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-47464181255487499272012-06-17T20:27:54.839+10:002012-06-17T20:27:54.839+10:00Does anybody know whether the Chorus or the Athena...Does anybody know whether the Chorus or the Athena work together with the 1992 Record shifters (index only).<br />See: http://velobase.com/ViewComponent.aspx?ID=B48AADA9-BFAB-4996-BC5D-B2BE53F7BE59&Enum=104&AbsPos=36<br /><br />These shifters were designed for the 1992 and later generation of RD's, which were all slant and had a cable adjuster.<br />But the Chorus/Athena from '88-'91 are slant too and have cable adjusters as well.<br /><br />The shift ratio or cable pull might be different, I don't know?<br />Who does?<br /><br />So, would this combination work? Does anyone have experiences with this set up?<br /><br />Thanks!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-87385378181828226472012-06-12T23:41:56.264+10:002012-06-12T23:41:56.264+10:00Sorry if I appeared nosy.

As you probably know it depends on the freewheel spacing and the travel of the derailleur. Each company is a little different and Sheldon Brown still remains the best source of such useful info http://sheldonbrown.com/cribsheet-spacing.html. If you really wanted to you can use a modern cassette with narrower spacing (using the appropriate chain of course) and with that it will definitely run 7 cogs as in the Planet X previously posted (running a Huret Jubilee). Friction shifters goes without saying.. Cheers & enjoy your new purchase!wingnuthttps://www.blogger.com/profile/11016671831457597440noreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-57227794232232182592012-04-09T11:10:28.594+10:002012-04-09T11:10:28.594+10:00The Malaysian Ebay troll just bought a bike with 1...The Malaysian Ebay troll just bought a bike with 1st gen C Record rear derailleur and has been scourging the net for info to no avail.<br />Just wondering if you could help me with a quick question?<br />Can this derailleur be fitted to work on a 6 and 7 speed?<br />Would really appreciate your help!<br /><br />KumarAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-89481182524744012762011-01-18T19:41:20.949+10:002011-01-18T19:41:20.949+10:00Great flickr account there anon!Great flickr account there anon!wingnuthttps://www.blogger.com/profile/11016671831457597440noreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-17610922557334846462011-01-18T01:05:24.614+10:002011-01-18T01:05:24.614+10:00I hope you haven't been affected to much my th...I hope you haven't been affected to much my the floods over there.
