Please, for the sake of the children, does anyone have a canonical set of measurements they can share for this hub, so I can try to get one of the online spoke calculators to produce something that makes more sense than the comedy length spokes that I'm getting out when I use the figures from the Shimano site. (I've read stuff online that claim the Shimano details might be 'unreliable' owing to variations in the way different hubs were measured - but how true that is tho' is who knows ...)
I'm getting >6mm differences between the DTSwiss and Sapim calculators online too and that's not helping (but that might just be my cack-handedness).
I'll be using a 32 hole, M756 (6-bolt) rear XT hub, 3-cross laced to a Salsa Semi 29er rim (605 ERD), and the most credible spoke length I've seen returned so far has been 293mm and 294mm ...
Ta!
