I have a Bianchi 928 frame that I put 2012 SRAM Red components on. I have installed the front and rear derailleur as described in the manual. Both derailleurs are working well and I can shift through all the gears and there is very little chain noise. The problem I am having is that when I am in the small chain ring and the smallest to cassette sprockets (gears 9 and 10) the chain slips or jumps on the front chain ring. It appears that possible the angle of the chain from the small front chain ring to the outside two cassette sprockets is too large. I have a Mavic R-Sys rear wheel and I have one small spacer (1 mm at most) between the wheel and the cassette.
Any ideas as to what may be the cause of the problem?
