different grouppos on Road and Tri bike

Always had a Simano build on my tri bike, but I'm thinking of running SRAM rival on my roadie for a change.  Can anyone think of any drawbacks to this?  As far as I now, the cassettes are interchangeable, and the only real swapping I can imagine will be my PT wheel. 

Thoughts?

    Should work fine.

    The only trouble I ever had interchanging cassettes was when I had a Shimano-compatible-but-piece-of Sh*t FSA crank. With the Shimano crank on the same bike, no problems at all.

    Try it out and see if you like the double tap shifting. It's strange for this Campy guy, but I think the group has proven itself by now.

    I have SRAM Red on one TT bike and Shimano Dura-Ace 7900 on another TT bike. My road bike has Shimano DA 7800 which shifts like butter...the best of the three. I rate SRAM Red #2 and DA 7900 #3 but they are work great...only minimal differences.

    Calling Mancona, he seems to be the gruppo guru.

    Consistency is nice for it can help interchangability, but mixing and matching is fine too.  I have Force on both my bikes (but Ultegra chains and cassettes) and I swap the Quarq between them.  I'm pretty seasonal with each of the bikes (Fall/Winter road - Spring/summer tri) but it takes only a few minutes for the quarq changeout if needed.  I like the double-tap over the shimano shifting.

    On a past bike I ran a campy crank with an Ergomo, and everything else shimano.  It was a unusual chimera, but worked just fine.  I think it makes a bigger deal when you (unsuccessfully) try and blend 11's with 10's.
