It appears that "no spacers" on the DS and "all spacers" on the non-DS is the only thing that gets them close to equal in the BB shell, and the chainrings still seem too far outside. The protective plastic cylinder gets torqued and starts to warp if I eliminate any spacers. And "all spacers" on the left leaves it with not much bite on the threads. Looks like I may go freestyle on this and shorten the plastic cylinder, eliminate several spacers, and possibly abandon that tiny latch pin (if the non-DS arm pushes in too far). Anybody know something I'm completely missing here? Maybe weird leeway using (68/73) MTB crank on road frame (88 850 is 26" wheel mtb frame supposedly, but the 68mm bb shell and 130 rear drops makes it more like a road frame)
