Shimano Deore XT FH-M732 135mm 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

Dimensions measured (quickly) in a laced-up wheel. Spoke hole diameter is a guess. Not able to weigh hub. Locknut to flange distance is 37mm. Freehub body is from the transitional time period between UG and HG and has both internal and external lockring threads. Note that the tip of the freehub body does not have truncated splines, so many modern 11t cogs will not quite seat down enough to compress the rest of the cassette, and loose cogs will result. You could file or grind the last 2mm of the splines down to the smaller diameter, or I had success by adding a 1mm spacer behind the modern 7spd cassette (CH-HG41-7) I was installing. -Karl
