Shimano Alfine DH-S701 (6v 1.5w) 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

9/27/18 -- This is a recently released hub model that has significantly less power output (LED headlights don't need as much power as old halogen bulbs that were the only option when 6v3w was standardized) and should have less rolling resistance than a 6v3w model. Markings on hub says it is intended for 492-716mm rolling diameter. Dims and weight taken by Karl on a new 32h specimen. Weight is with wire connector and rubber Centerlock cover but no skewer. -Karl
