I'm trying to swap out my old crankset for a a spiffy new mountain crankset. The LHT frame has a 68mm bracket, at least according to Surly. Shimano's instructions say to put two spacers drive side and one left side in this case.
Yet doing so leaves the chainrings half a cm out from where the deraileur expects them. I can easily remove the two spacers on the right, but:
1) does this mean I messed something up?, and
2) should I remove the spacer on the left side?
