I installed SRAM BB (DUB T47 Road Bottom Bracket 85.5mm) with SRAM Force E1 2x crankset. Using 3mm spacer that came with BB, my non-drive side has bit of too much empty space. There is no play and I could not move it sideways. Plastic ring is maxed out, and it jumps if tightened more.
Torqued crankset to 54 Nm according to guide. Did I mis something or just need to order extra spacer?
That's not a spacer, it's the crankset bearing preloader. Loosen the screw on preloader and turn it all the way to the non-drive crank arm. Then tap the center of the drive side crank with a plastic or rubber mallet with mild force to get it in as far as it wants to go. Then turn the preloader til it *just* makes contact with the outside of the bearing cover on the non-drive side. Now tighten the small screw. It only needs to be tight enough to not loosen itself.
