I’ve built my own bikes for years, but this is the first time I’ve used a crankset that doesn’t require a cartridge-type bottom bracket, so this too is unfamiliar territory for me.
I installed a Dura-Ace 7900 bottom bracket (English type) and Dura-Ace FC-7900 crankset. In installing the non-drive side crank, I noticed that there’s about 2mm of the crank's splines showing past the axle, almost as if the axle is 2mm short. The drive-side crank is pushed in all the way.
As far as I know, these cranks are compatible with both 68 and 70mm bottom brackets shells. I didn’t measure mine, but I assumed it’s 68mm since the threads are English type. (The frame is a Ridley Noah RS.)
Is it normal to have some of 2mm of crank not supported by the axle? Or have I screwed the pooch somewhere?
