Shimano FH-M6010 142mm Rear hub

PLEASE NOTE: Shimano publishes hub dimensions in a relatively confusing manner on bike.shimano.com. They seem to provide the outside-to-outside flange spacing, and an overall offset of the flanges as a whole. Wheelbuilders are interested in the distance from the midpoint between locknut faces to the middle of the flange (not the inside or outside face). When necessary, I convert Shimano's data into useful spoke calculation dimensions with some simple arithmetic, and factor in 3mm thick hub flanges (an approximation). The formula is to divide spacing by two, add or subtract the overall offset, then subtract half of our assumed 3mm flange thickness. Please check the notes to see if the values for this part are derived from Shimano's published data or actual measurements of a hub specimen. -Karl

NOTE: Flange spacing on bike.shimano.com is listed as outside-to-outside spacing and an overall offset. Wheelbuilders are interested in the middle of the flange relative to the midpoint between dropouts, so these numbers have been based on published values and adjusted by half of an assumed 3mm flange thickness. Ideally the offsets can be verified on a real specimen at some point. -Karl
