Hello everyone.
I'm installing a good old Shimano m770 external BB crankset in my new Niner air9. I'm using inserts provided to me with the frame. The drive side has ~1mm flange and non drive has no flange and presses in flush. I was also supplied with a ~1mm spacer.
So which side does the spacer go on?
Common sense would tell me the drive side, as this is normally where a 2.5mm spacer goes with a 73mm shell (see:
http://techdocs.shimano.com/media/t...02/SI-1J10A-002-ENG_v1_m56577569830680226.pdf
).
However I seem to recall someone knowledgeable telling me it goes on the non-drive side. I do trust my common sense more than both my sieve-like memory and arguments from authority, but I am still not quite sure.
The Niner encyclopedia (https://s3.amazonaws.com/NinerDocs/NIN_OWNERS_UNIVERS.pdf) isn't helping me out a great deal; and in fact my inserts don't look like any of those listed.
Anyone know for sure?
