Shimano Hollowtech Bottom Bracket Spacers
thingiverse
0.7, 1.8, & 2.5 mm spacers for Shimano Hollowtech II bottom brackets. The ones that came with my How I Designed This http://wheelsmfg.com/bottom-bracket-spacers.html I have my own spacers, but I used this website to make sure they were in fact bottom bracket spacers. I ended up pulling off the dimensions from the ones I have. The OD doesn't matter as much - 40.88 mm, & 35.52 mm ID, which does matter. This ID is larger than the 1.380" = 35.052 mm specced by Wheels Manufacturing. Assembly http://si.shimano.com/pdfs/dm/DM-FC0002-12-ENG.pdf See page 11, or any Shimano Hollowtech II bottom bracket tech doc. 68 mm bottom bracket shell needs 3 spacers: 2 on the right, & 1 on the left, all 2.5 mm thick. If you're using a mountain crankset, that is.
