Sram Force Drivetrain Help
I'm building up a bike with 2013 Sram Force 10 speed, with a compact crankset and 11-23 cassette.
It's my first time doing a build. If I'm in the big ring, the chain tension seems right, and I can shift through the cassette. If I move to the small ring, the chain has tons of slack, and the rear mech is near-horizontal such that the chain rubs on itself as it passes through the jockey wheels. Any ideas on what the problem is? Did I install the rear mech incorrectly? Too much chain length? B-tension screw?
Thanks in advance. I'll post some photos tonight if people don't understand the problem.

Yes, go to Park Tool and size your chain.
