Are SRAM Rival/Force/Red brifters compatible with any SRAM mtb derailleurs? I ask because I'd like to run a SRAM 10 speed drivetrain with 11-30-something rear cassette. So I need a derailleur that can handle a cassette with a max cog of 30-something teeth and at the same time be compatible in terms of cable pull.
On a side note I gather that 10 speed SRAM, Shimano, and Nashbar etc aftermarket 10 speed cassettes are all interchangable.
To put the question another way: what do you do for a rear derailleur if you want to run a full SRAM drivetrain & shifters on a cyclocross bike having a standard or compact road double crank? Where the rider in question most definitely wants to run a rear cassette of at least 30 max teeth?
