I have recently acquired some Sugino 75 Cranks, as I set out to install them on a 107mm Shimano UN73 Bottom Bracket I encountered a snag. It seems that there is a gap, approximately 1/4", between the center of the chainring and the face of the cup. This has undesireable effects on my chainline, not to mention the gap looks really weird (the same gap appears on the non-drive side too). I was previously told that with track hubs the Shimano bottom bracket and the Sugino Cranks would provide a straight chainline - needless to say I no longer believe this.
Does Sugino use a different taper than Shimano? Has anyone else experienced similar frustrations?
If any one out there is using Sugino cranks what bottom bracket are you using, how is your chainline, and what hubs are you using?
