Inexing conversion - more Campy questions
For a Campy Racing T derailleur, what is the maximum cog in can
accommodate, and what is the chain wrap capability? If I get a used wheelset with a Campy Record 10 speed hub, do i need to use the Record cassette or can I use a cheaper one. Will the cheaper cassettes affect (i.e. wear) the aluminum freewheel body on a Record hub?. Thanks! Ken (aka Road Fan, but my true secret identity is kenbikeman) |

Inexing conversion - more Campy questions
I'm no expert but I recall my Racing T's came with literature
suggesting they were made work with up to a 28 rear cog. Isn't that the largest that Campy offers as well? I'm pretty sure you could set it up to work fine w/ a 30 if you adjust it and the chain length carefully.

On my long cage 9sp Veloce, I have an 11-32 SRAM cassette with conversion spacers, and a 52-42-30 Veloce crank. The RD clears the 32t cog just fine, but I need a 116 link chain (SRAMs come standard at 114, Shimanos are 116) and have a little droop in the 30-11 combo, which should never be used anyway. My setup has 43t of difference, so I guess that would give a total capacity of a hair under that - 40 or 41 teeth of wrap? The Racing T rear derailleur was a medium cage. Back then Campagnolo had short cage and medium cage. They now make all of their rear derailleurs in short, medium, and long. The long is very long. I tried a medium cage with a 52-42-24 rings and 13-28 cassette. The medium cage did not wrap up enough chain for me when using the inner ring with the smallest 4 or 5 cogs. Long cage works on all cogs with a 24 inner ring. My short, medium, and long cage rear derailleurs all clear a 28 tooth rear cog. Medium and long clear a 29 tooth rear cog. Never tried the short cage with the 29 cog. |

Never tried the short cage with the 29 cog. Anybody have the cage lengths for what Campy considers long and medium these days? If I go with Campy wheels I'll use the 13-29 10 speed, and if I go with Shimano wheels I'll use (probably) the Sheldon custom "Century" pattern, 13-30. With a 52 T large chainwheel, I don't need any gears taller than 104 inches. How do I tell what year my rear derailleur is? I don't see any patent marks. The cranks don't have any diamond numbers on the arms, like Nuovo Record and Super Record. The chainwheels do have some markings, and diamond C's. I assume my front der, rear der, and crankset are the same year, since the Ebay seller said they were take-offs from same new bike. Not reliable, but the best info I have. Ken |
