Unfortunately, SRAM's 11-speed (and now 12-speed) MTB systems use a new "X-Actuation" ratio that makes them incompatible with their 11-speed Road systems (which still use the Exact Actuation ratio). Tim- As others have pointed out, 3 x 10 indexed Shimano is completely possible. You can use the 7900 downtube shifters with a 9-speed MTB long-cage RD; these parts all use Shimano's "SIS" ratio so they're compatible. On my Riv Road Std, I use the 7900 bar-ends with a 9-speeed XT M772 RD, and they index a 10-speed 11-32 cassette perfectly while taking up enough chain for my 52/42/30 Campy triple crank. Don't get talked into 3 x 9 bar-ends (which are great if you like them) if you really want 10-speed downtube shifters. FYI, if you want to have both friction and index possibilities, find a set of 7800 shifters. The 7900 shifters are index-only for the rear.
