Spacers to Adjust Chainline on GXP BB?
I have a Truvativ/Sram Stylo crankset designed for a GXP BB. Its a single speed with bashguard setup. I want to use this on a 1x9 setup. I have a 68mm BB shell. For a 68mm BB, the manual says to put a 2.5mm spacer on each side. I would prefer to have the chainring closer to the bike frame as I will generally be riding in a lower gear in the rear. In other words, I want a straighter chainline when riding 32x34 than when riding 32x12.
What are my options?
Can I add another spacer on the NDS to bring the whole crank to the left? Guess it would be off center then.
Are there spacers to move just the chainring inboard a mm or two?
Thanks.
