Went for a ride this morning to test a new bike I built for my wife. Mix of SRAM with KMC X10SL chain. Everything except levers is new. Bike shifted fine for the most part, I was going to fine tune after the ride. Anyway, came to a stop light and when I clipped in to get going again the chain got "stuck". It happened almost immediately after I tried to get going again, I don't think I turned the crank even 1/2 revolution. I looked down an the chain was bunched up/twisted right behind the FD cage.
