I went 2x9 by dumping the granny ring off my FSA carbon pro crankset. Can anyone tell me how I should align my front rings to my rear cogs? I have got a RaceFace signature XS BB, so I can change my chainline.

I use a Middleburn XC Duo on my Giant ATX, The spindle length for this chainset is 107mm. Hope this is of some help!!

Thanks Nobby,

Could you tell how much room you have between your big ring and the center of your frame?

Never mind! It turned out that I had not installed my cranks correctly. I did not know that ISIS cranks should be tightend until the crank reaches the stop on the spindle, so they sat too far out.

always torque spec your cranks. the spec for isis ir splined systems is slightly higher than the standard square taperbb's. it should be around 35-36lbs. depending on crank
