The reason for this question is i can get a really nice campy rear derailleur cheap but i have a rear shimano cassette. as for shifters i can get eitehr shimano or campy(9speed)
You will need Campag shifters and cassette if you use a Campag mech. Just not worth the hassle. If you must, then some companies (American Classic springs to mind) do an M10 cassette with ED10 (Campag) spacing.
for the rear mech you will need campag shifters. i dont think a campag chain will run on a shimano cassette but you can have one made by marchisio. i know pearson in sutton have them but im not to sure about any one else
It'll work with a bit of tweaking but it'll never be as good as a full Shimano or full Campagnolo set up. And the Fashion Police will arrest you.
With Shimano shifters it should be fine since it's all down to the amount of cable being pulled. With Campag shifters and a Shimano cassette it'll need a lot more fettling.
My 10 speed campag shifters with 9 speed shimano cassette, 9 speed Shimano chain and Shimano rear mech with the cable fixed in the hubbub method works perfectly on my CX bike.
Had the same thing a while ago, Campag shifters and mech, on a Shimano cassette.
I kinda worked, but there was always a couple of gears that just felt like they weren't indexed properly. So I just flogged the Shimano wheel and bought a Campag one and cassette. It was a lot better.
Stick to one or the other, or the fashionistas will be onto you.
Surely the sensible option for what you're trying to do (eg must use your existing 9 speed cassette) is just to put on a shimano mech and shifter and mount the shifter to the frame in one of the various ways people are already doing which seem to work? Or am I missing something?
OK Red is marginally lighter, but it's also got ceramic bearing jockey wheels which account for the difference! Considering the XX rear mech is double the price of XTR for a 1g saving, I don't think Shimano stuff's particularly heavy!
This does come back to why you're using lightweight kit on a jump bike though?
Well theoretically then you'll need to use the 7900 TT shifters. Basically, ideally your mech and your shifters should match, so if you're still wanting to use the R2C shifters then I'd get a Red mech.
Either of those will only work properly with a 10 speed set up, but I'd think the last thing you want on a jump again is a thin chain and a cassette with ti sprockets you could break more easily.
Njee – Well im already running a 9speed ti cassette on the rear, thats why im looking for a new lighter derailleur along with some shifters that are ideally indexing (i can live without r2c) and bar ends, the bar end shifters would be easier for me to use and mount to my bottle cage than say a trigger.
Why not just go for Saint in the first place then! Saint won't be light but would clearly be a more sensible option, along with the Saint shifter but you seem hellbent on weight saving above all else!
you'd save more weight and be a lot safer if you just had a kidney removed rather than trying to shave weight off componenets that'll lleave you broken if they fail.
saving 4 grammes on a mech is really not going to make any difference on a jump bike…
But if you're starting with a 16kg bike you're looking at the wrong parts, change your wheels, tyres, forks etc if you want to get that down, not several hundred pounds on carbon rear mechs.
16kg?! What's it made of, that famous alloy of depleted uranium, lead and granite?
Can I suggest that your weight saving starts with a new frame and some new wheels. Then worry about the rest of it…
