im about ready to pull the trigger on a custom cx bike and i have some component questions?
1. Can I run SRAM red Shifters, Crankset, and front derailleurs with SRAM XX1 cassette and rear derailleur all on a bike with disc brakes (avid bb7 sl)?
2. Can I run Shimano Alfine Di2 11-speed hub in the back with a shimano ultegra Di2 up front (shifter, crankset, and derailleur)? if so, what chain and brakes to go with?
