I'm currently rebuilding a 1992 Kona Cindercone as a 1x9 commuter. The rear spacing is 135mm and the bottom bracket shell is 68mm.
I've mounted a alfine crank on it and remove the spacer that what installed on the drive side of the crank and put it on the non drive side on the crank.
The chainline looks okay and both crank arms seem to be at the same distance with the chain stay. However I now have that massive spacer in between my crank arm and BB cup and I'm sure this is plain wrong.
I also have no experience with hollowtech cranks.
Here are some picture to illustrate my problem:
So what am I doing wrong here? Thanks
