hub dimension diagram
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
This is a new hub that will be released around September 2010. The hub has 11 evenly-spaced gear ratios covering a range of 409%.

It is similar to the 8-speed Alfine, but has been completely redesigned. Three major design changes from the 8-speed Alfine hub are:

- helical-cut gears (instead of straight-cut)
- oil bath (instead of grease)
- high-normal shifting (instead of low-normal, AKA RapidRise)

I can't find the actual gear ratios or any wheelbuilding dimensions yet, but I'm sure they will show up at some point.

All dimensions measured by Karl. (weight is still as quoted on spec sheet, spoke hole dia could use more accurate measurement)
