Hi forum goers,could I ask a question ? I have 9 speed Centaur ergos, a 9 speed Ultegra cassette and a Dura Ace rear mech - model RD-7402(8 speed I think), Will I have to route the cable in a certain way to get the shift correct?
Please don't tell me it can't be done
If it will work, is it better to run 10 or 11 tooth jockey wheels on the rear mech?
Cheers
