Shimergo.........?

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

No problem, it can be done with one of these: www.jtekengineering.com/shiftmate.htm
I presume they'll ship to the UK

There is no Shiftmate for what he wants. Shimano Durace 8 speed had an oddball pull length. If you look closely they don't mention Durace 8.

The answer is NO. Get Shimano 9 or 10 speed rear and it will work. Better still, buy a Campy rear, they are on sale now. 2006 parts are being blown out. Good luck.

I also think someone manufactures a cassette that will fit Shimano but is spaced for Campy. But if I remember correctly they were quite pricey. Probably cheaper to go the derailleur-shiftmate route rather than derailleur-special cassette.

The combination of a Shimano 9-speed rear derailleur and a JTek Shiftmate will probably be your quickest and cheapest solution. Alternatively you could use a Shimano 9-speed derailleur and a custom cassette built by Wheels Manufacturing or American Classic. Using a Campy rear derailleur with a Shimano shifter would NOT be good because of the difference in cable pull and throw ratios, similar problem with the 8-speed Dura-Ace rear derailleur.
