Campag / shimano casette compatability

Morning all

Has anyone used a shimano 10 speed block with a campag drivetrain? I'm thinking of getting a campag equipped bike for the first time but want to know if I can swap wheels with my existing Shimano equipped bike?
Thanks in anticipation!

    not if you want it to shift cleanly - the spacing is different

    yeah, i could never get a 10sp shimano cassette to work with 10sp centaur.

    it always missed one cog going up, down seemed to be ok.


    i got this http://www.surosa.co.uk/3896/products/A ... paced.aspx

    No reason why not. As long as you set up gear number 5 exactly right. The blocks are less than 2mm difference in width so if you set No. 5 exact then 1 and 10 will only be 1mm out. It'll work.

    1mm. It will rattle like hell John. Unless it is all worn out stuff with loads of slack in it. As you can ignore the top gear as it is controlled by the limit stop you should try this on no6 (from small end). You will still get rubbish changes at the extremes. There are some combos that work. Campag 9 with a Shimano 10 cassette I believe but you loose a gear.
    You can get spacers to convert a Shimano cassette to Campag spacing but you can only do this with low end cassettes without the alloy carrier. The freehub will only take 9sp at Campag spacing.
    This is why I have never tried to use Campag. Not because I have anything against it but I have too much Shimano kit and am happy with it.
  • Thanks for your replies gents - looks like it's back to the drawing board................ :roll:

    I have a 10spd 105 cassette with an other wise Campag drivetrain on my turbo wheel. Works fine.
    I like bikes...

    Shimano freehub is shorter than Campagnolo so creating problems fitting the cassette.
    Make mine an Italian, with Campagnolo on the side..
  • I've run this for 6months, Veloce with a 105 cassette, after two sets of pathetically designed 105STI levers exploded I replaced it with veloce ergos and mechs. It works, just not perfectly, as in it doesnt slip gears, but when you shift, on the odd occasion it will shift two gears not one.

    For next summer I might buy some campag wheels or look at one of the jtek shiftmates to perfect the shifting.

    Overall now i would'nt go back to shimano on my road bike...the trim on the front mech is brilliant, ergos are simple and effective, and dont cost £200 a pop.

    There used to be some useful info on http://www.highpath.net/ under Successful indexing
    but it seems to have gone

    it had info about cassette / sprocket spacing

    7 speed (all makes) 5.00mm
    8 speed (Campagnolo, Sachs) 5.00mm
    8 speed (Shimano, SRAM) 4.80mm
    9 speed (Campagnolo) 4.55mm
    9 speed (Shimano, SRAM) 4.35mm
    10 speed (Campagnolo) 4.15mm
    10 speed (Shimano) 3.95mm

    This spacing is not the thickness of the spacers between the sprockets.
    But the distance that the rear-mech (jockey-wheels) have to move (sideways) to move the chain onto the next sprocket to be directly under the middle of each sprocket.

    On a 10speed Campagnolo cassette the chain has move across 9 x 4.15mm = 37.35mm
    On a 10 speed Shimano cassette the chain has move across 9 x 3.95mm = 35.55mm

    Even with the floating upper jockeywheel on Shimano rear mechs that is almost 2mm of missalignment to compensate for.

    With a Campagnolo rear mech (with no floating jockeywheel) and a Shimano cassette its not looking so good.

    It is not quite that bad as the top sprocket is not indexed as it uses the top limit screw on a slack cable so you only need to allow for the rest. I still would not bother.

    IRD do a road conversion cassette so you can run Campag on Shimano hubs. 'Kin expensive though.

    I'm sure I've seen somewhere that if you route your cable around the oposite side of the clamp bolt it will work a shimano/campag combo?
    Doing this alters the pull ratio enough for it to work.
    I may be wrong

    You might find a solution here using a shiftmate: http://jtekengineering.com/shiftmate.htm

    You are talking about the hubub method of routing the cable to run 9 speed shimano with 10 speed campag. You actually just turn the lock washer round 90 degrees and route around the tab. It works well.
