Shimano DH-C6000-2R-N 100mm Front 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

6/30 -- Measured a new 36h specimen.
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 2.4w, total weight 65-120kg, for wheel size 646-716mm. -Karl
