Okay. I just spent 45 minutes searching for the physical specifications of the NuVinci hub. All I can find is a passing mention on the Staton site that the diameter is 5.9 inches. Some help, not enough.
What I need are the following spec:
1) Hub barrel diameter;
2) Spoke flange diameter (and thickness)
3) input sprocket diameter/tooth number (typical)
4) Axle diameter;
5) rear drop out required width (I have that as 5 3/8 inches, but I'm not sure I am correct)
6) Hub width
If anyone has them, I could use the specs on the hub as supplied by Staton for use as a mid-drive;
7) secondary (power assist) sprocket diameter/tooth count;
8) output (spoke flange mounted) sprocket ring OD and thickness. In addition, can that output flange mounted sprocket ring be mounted to either the right or left flange on the hub? I sure hope so, as it will make chain run clearance issues much simpler for my trike design.
E-mailing Staton has been utterly fruitless. I am at the point where continued fabrication is at a full stop until I have that info. If I culd, I'd just buy one, but as I am designing this trike the NuVinci hub will become a mid-drive to replace the old shimano internal hub I'm using for now. I really, really don't want to have to rebuild the rear swing arm totally when I finally do get a NuVinci hub
