9 speed rear derailleur
Since the biggest and smallest cogs aren't any farther apart on a
ten-speed cassette, what is the obstacle to using a nine-speed rear derailleur with a ten-speed shifter, cassette, and chain? Is it the pulleys? AK |

Or is it because they genuinely want their customers to have the best and are terribly consevative? 2001+ 9-speed rear derailleurs are virtually the same as the 10-speed versions (geometry and ratio is the same, AFAIK). Effective width of 10sp pulley wheels is slightly narrower (different spacers). From memory, difference is 0.2mm or 0.4mm. ~PB |

Pete- Effective width of 10sp
pulley wheels is slightly narrower (different spacers). From memory, difference is 0.2mm or 0.4mm. BRBR Nope, they are even marked 9/10s for Campagnolo...

BRBR Now checked: Difference is 0.4mm Nope, they are even marked 9/10s for Campagnolo... By effective width, I mean width of jockey wheel plus spacers (washers or whatever you call them). I believe the spacers are different. The actual jockey wheels may be the same. 2004 Veloce 9-speed total width: 8.8mm, 10-speed Veloce: 8.4mm.

BRBR No obstacle, just use it whether it be shimano or Campagnolo. no need to change anything. The shifter makes sure the chain moves the correct amount these days.
