http://www.rotorbikeusa.com/pdf/bsa30_bb_manual.pdf is the manual for the BSA30 setup. Spacers come in 3 and 5.5mm. So, I need a 3mm and place it on the drive side and let the preload bolt fix the other 2mm?
I had to put an 11.5mm + 2.5mm on my OSBB Tarmac to get my Rotor Power to fit which put the chain line out causing chain suck. I've now sold the Rotor Power and switched to S-Works cranks with Type S Power2Max
