Hey guys, I've just began cycling and have bought a Dura Ace 7900 Group without the crank set. The final piece I am buying is the crank set and I was wondering if I should get the Sram Red Crank set. I like the Dura ace 7900 crank set but it seems way to expensive and once I wear the chain ring, I might as well buy another crank set since the chain rings are about $400. Has anyone seen people with Dura ace 7900 and a SRAM red crank set? Is it not cool to mix Shimano with SRAM? Please, please let me know. By the way the SRAM Red Crank set will cost me $230.00.
