SRAM on Shimano

[7rider]

Thanks all.
I did some checking around.
According to the Shimano website...the DA max spread is 11-27T (XTR and DA are both Shimano high-end, BikerZ, which is how they are "equivalent", I suspect, but the short cage of the DA vs. the long cage of the XTR result in different capacities for the spread on the cassette), so the SRAM cassette is within that. The SRAM site says that the PC1090R PowerChains - and others - are compatible with Shimano Gruppos, but doesn't talk about the 1070 Cassette re: compatibility.
It sounds like you all are not having shifting issues, so that's great to hear!

It is compatible. I run sram rival on my bike, and the deciding factor for me when I decided to go with it, is its compatibility with shimano(in case I need a teammates wheel at a race or something). I even ran a campy rear wheel the other week and it all worked beautifully.

So I say, go ahead! It will be compatible with your shimano that you are running.

I think the only thing you can't mix and match between the two brands are SRAM derailluers and Shimano shifters.
