hello ratz, a quick question on the rwc bb. Do you use the wave washer on the SRAM cranks or just tighten them up? I have used the two 1mm spacers between the frame and r/l bb another question is do I use any covers between the rubber gaskets and cranks? I have a strange washer marked 24x1mm that was in the packet with the wave washer. Is this used or is it for a different setup? Thanks.
