Anyone Using Chorus 9 Speed Shifters With Dura Ace Cassette(6 posts)

Anyone Using Chorus 9 Speed Shifters With Dura Ace Cassettejzinckgra

Ok, one other question. I'm looking at the 2001 chorus 9 speed shifters, but have to use a shimano cassette (shimano free hub on Hugi hub). Specifically I was thinking of the 7700 shimano 9 speed cassette. Other than having to possible change some of the spacers, has anyone done this?

As I understand, there are spacing issues between Shimano cassettes and Campy Ergo shifting. There is a solution for you from Branford. They sell the spacer kits and cassettes for Shimano to do just what you are looking for.

There are typically spacing issues between Shimano and Campy, but in the case of 9speed, the system will work well. I actually had a customer who prefered the Shimano cassette to the Campy one. And if you take this route, you should use a Dura-Ace chain.

Most of the time you've been on the mark with your advice. Can't agree this time.

Campy's cog spacing is 4.55mm and shimano's is 4.32mm. That's a 5% accumulative error on every shift. Even if you are able to perfectly align the rear derailleur with middle cog, you end up with 20% misalignment after four shifts. The misalignment could be as bad as 40% if the derailleur isn't carefully adjusted. Better to get one of the campy spaced cassettes that are available.
you need a wheels manuf. cassettewes_london

at excel they sell wheels manufacturing 9 speed cassettes that fit shimano pattern hubs but are spaced for campy shift pattern. its the only way. you can use shimano 9 speed cranksets but you will need a campy rear derailleur. the difference in chains is neglible between the two. the good part is that you save some weight as campy levers are lighter and shimano cranks are lighter. the wheels cassette is limited for ratio sizes though and cost a big $100. see the listing at excel sports. i am not sure about changing the spacers but if you have any luck please let me know. wes_london@mac.com
