Group set Compatibility
 

With goal of installing my Campy parts in a new frame which is equipped with BB30 bottom bracket shell and bottom bracket, I want to use a SRAM crankset. Meanwhile, I have Campy 10-speed ("10s") parts that I like a lot.

Can I run
SRAM Red 10s crankset, chain, and cassette - with
CAMPY Record 10s brifters, derailleurs, cables, brakes ?

Any problem(s) anticipated? Can the sprockets on rear cog be spaced to approximate a Campagnolo cluster's spacing, to achieve reliable shifting behavior? Would this be necessary? Are there certain cassettes that I need to source to be able to space the cogs?

Will the little wheels of the Campy 10s Record rear derailleur engage reasonably well with the link spacings of the SRAM chain?

Any other issues to watch out for?

Thanks!!

You can use a SRAM 10s crankset with Campy 10s stuff, but you'll want a Campy 10s cassette if you're using Campy shifters

Chains all have the same length between cog teeth.

Your campy shifters work with campy derailleurs to move the chain a certain amount each shift. For 10s, that only really works with a Campy cassette.

You used to be able to find cassettes that had 10s Campy spacing that fit on Shimano/SRAM freehub bodies, if you are putting together a bike that has a Shimano/Sram rear wheel

Just change the crankset and BB - nothing else.

In addition to maintaining good shifting, this is cheaper and means you can continue to use your campy wheels.

I once tried a Shimano cassette with my Campy 10s bike and it didn't work well. Just stick with all Campy. I think SR and Shimano have the same spacing.

Also, I have another bike that has friction shifting, a 9speed Shimano chain and a 10sp Campy cassette and that works well. I was surprised that a 9sp chain would work. I haven't been on the bike in over a year, maybe I should take it for a spin. It is all original Campy SR pantograph. I have the original wheels, but the modern wheels ride much better, and 10sp shifts really well with friction shifters.

And you'll need a Campy compatible freehub. Campy uses a different spline than SRAM/Shimano.

Yep, but if the OP has a Shimano/SRAM freehub rear wheel, you can still get the cassettes that have Campy spacing and Shimano splines:

Have fun. Stuff gets complicated above 8 speeds.

True. I've used the Miche version. It's heavy as hell, but works pretty well.

11-Speed Compatibility
 

Thank u 2 posters who replied, the My research suggests that the best way to integrate a SRAM drivetrain with Campagnolo shifters would be to equip the frame with Campagnolo 11-Speed brifters, derailliers and cables; as well as Campy Brakes... Would Campagnolo Athena 11-speed work fine? It costs less than 11speed Record!

It would be useful to know what parts you already have. You mentioned having some components on hand. 11 speed Athena brifters will work just fine with an older set of Record brake callipers. However if you already have a full 10 speed Record groupset, it would be useful to know what rear wheel you currently have, it would be cheaper to buy a Campagnolo compatible rear wheel if you already have a Campagnolo cassette. If you also have a Campagnolo crank you could use an adapter to use it in the new frame. The most useful suggestions will come to you if people know what you are working with. If you currently have a rear wheel designed for 8,9 or 10 speed Shimano cassettes you would need a new wheel or at least a new freehub body to switch to 11 speed

Has anyone used 11-s SRAM drivetrain with 11-s Campy Shifters?
 

I was not posting a question about the inter-compatibility among Campy parts. Rather, I meant to inquire after feedback regarding whether an installation of a SRAM crankset, chain, and cassette could work fine with Campagnolo brifters? I believe that the 11-speed parts are quasi-compatible among the 3 big manufacturers. But I also do not want to do anything stupid like buy parts I cannot actually use together. Thanks for allowing this clarification to my original post.

The reason why you are getting answers about inter compatibility of Campagnolo parts is that you asked about buying an Athena 11 speed group, including brakes which would not be needed if you already have a set of brake callipers with your 10 speed parts. The reason I asked about listing all the components you have on hand is that soemone here might suggest a good solution that would allow you to use more of the parts you have on hand at less cost to you, a solution that you couldn't have thought of. The fact that you asked whether a SRAM 10 speed chain would work on the pulleys of a Campagnolo 10 speed derailleur is a warning flag. A 10 speed chain of any brand will work on any 10 speed drivetrain regardless of brand. That you didn't seem to know this indicates that you probably haven't considered everything. Campagnolo 10 speed derailleurs and shifters are not compatible with a SRAM or Shimano 10 speed cassette.Not knowing what wheels you are working with makes it impossible to tell you what cassettes you can use. If you don't want to buy parts you can't use, list all the parts you have now so that people can look at the list and find you a solution

Is the Shiftmate still available? I thought I heard that the manufacturer gave up, or maybe died? In any case, some people loved it because you could swap it in or out, and it worked.

When I bought my Campy Chorus 10sp bike 10 years ago, I asked at the shop if I could use my Shimano/Velomax wheels. The answer was no, at least not if you wanted perfect shifting after dropping $3400 on the bike. Why kluge up an expensive bike? I did try them at some point, but as I already posted it didn't work well. As for Campy spacing on a Shimano/SRAM splined freehub and cassette, the inner limit is very tight and the two systems start at a different point. We're talking millimeter fractions here but it is surprising at what a difference they can make. Wheel dish usually has to be a little different.

I took the plunge into Campy and my only regret is that the replacement parts are so expensive. OTOH, I broke the right brifter in a crash and was able to get it re-assembled by Branford Cycles (are they still around too?). Try doing that with Shimano.

Will these combos work? Sure. Will they work flawlessly? Nope.

One type of shifting though that works a lot better than you'd think is friction shifting with the 10sp (or even 11) cassettes. With the ramps that are built into the cogs on modern cassettes, friction shifting is silent and effortless. Spacing is tighter too. A small touch of the shifter is all it usually needs, the chain will ride on the ramp to the next cog, or even skip multiple cogs, and land centered. There isn't any slop like in the old days of 5 or 6 speed, so no clanking of the chain between gears. It really works well.
