I’m progressing my hardtail build slowly, and have a further couple of questions I wonder if people can help with. For reference, the frame is a Ragley Big Al (with 73mm BB shell), it’s a Shimano MT800 BB (with a single spacer on the drive side), Shimano SLX 7120 cranks and Shimano SLX M7100/M7130 chainring.
1) How important is the tightness of the chainring lockring? Does it matter if it isn’t the 35Nm specified? I’m waiting for a tool to arrive (from China as it’s a fraction of the price of the Parktool equivalent) so I can only do it hand tight for now.
2) On installing the cranks, there is a gap between the crank and BB – per the image below. I wasn’t expecting to need spacers, but a couple came with the cranks. I believe the non-drive-side crank is installed correctly onto the shaft/splines as the little plastic sticky-outy-thing presses in ok.
…if I do need spacers, how do I know which side to put them on?
Thank you!
