Are the DA7900 rear hub measurements the same as the Ultegra 6700? My spoke calculator only knows about the DA. Thanks.

Dura ace hubs are significantly different from Ultegra and other levels. 6700 should be the same as 6600.

I built my training wheels up with a 6700 rear hub and came up with these measurements -

Centre to NDS Flange - 34mm
Centre to DS Flange - 17mm

Spoke hole circle - 47mm (outer to outer, centre to centre would be 45mm)
Spoke hole diameter - 2.3mm

Weight - 354g

Hope that helps.

EDIT - Interesting that it's different. I'm wondering if I measured in a different way to Shimano as I measured centre to the near side of the flange. If you add the 3mm for flange width you get a similar result to the Shimano tech doc for 6600.

Ok thanks everyone. I found another place that had the FH-6700 same as the 6600 from the tech docs, so I went with that. Fingers crossed ...
