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

11/8/22 -- Measured a new 36h specimen. Box says DH-C6000-3R-NT (nutted axle) while hub shell says DH-C6000-3R-H. There is also a QR version. Weight of this NT version without brake or any axle nuts installed is 962g. This one came with taillight voltage regulator but no axle nuts...

Note that roller brake retaining nut needs to be installed to establish the proper left side locknut position to make the hub 100mm spaced. Shell is labelled 6v 3.0w, total weight 80~140kg, for wheel size 646-716mm. -Karl
