Campy shifters, rear der./ with shimano?(8 posts)

Campy shifters, rear der./ with shimano?Sharky

Has anyone ever tried Campagnolo shifters and rear der. with Shimano cassette, chain and cranks? Does it work well? Thanks

yep, it works fine with mine although I do run Campy cranks. 9 speed spacing is identical, you just have to adjust a little if you switch wheelsets back and forth that are Camp and Shimano cassettes, they start at slightly different positions from the small cog. Otherwise I never have any problems.

Campy spacing is 4.55mm and shimano is 4.32mm. That's 5 percent accumulative error on every shift. To get the best results you have to center the derailleur on the middle cog to split the error equally between upshifts and downshifts. If you don't, the accumlative positioning error can be as great as 40% after 8 shifts.
I always hear it's the same?climbo

maybe they just say that because it's close enough if you get it dialed in OK, I've never noticed it that badly but now I know what to do if I have a problem, thanks.

you have the important part right as both your shifters and rear derailleur are campy. any fron der. will do.

the spacings between cassette cogs is slightly different between shimano and campy.
this small difference ads up and on the extremities of your cassette range you will notice the loss of shift performance.

not sure about chain compatibility. dont see why it should be a problem. i have a similar set-up and opted for a sram sachs with a powerlink.

no problems with the crank as both 9 speed shimano and campy is very compatible

a lot of wheel options are open to me using this. if you already have a shimano cassette they also sell spacing kits to fit yourself.

i am actually selling my Wheels Manu. 12 x 23 cassette with about a 100 miles only as i am looking to get a 11 x 21.

if interested

The only things that really have to match are the shifters and cassette. Those are spaced very specifically. The derailleur will follow the shifters, just set the limiter screws, so it doesn't really matter what rear derailleur you have. The front derailleur and crank don't don't really matter (unless you ask Shimano :-). And if you stretch things a little, you can even make "incompatible" cassettes and shifters work together. Be careful on that one, though.

Campy shifters won't work with a shimano rear derailleur. The amount of cable pull per shift is not the same.

Campy shifters will work any front derailleur.

you can make some incompatible thigs work by adjusting the place where you clamp the cable. the main thing to try is to clam the cable on the oposite side of the screw than you are supposed to. this will give a different geometry to the deraieur and just might work a little better.
