For the "Old Hub"
"Old Hub":
This means: If your bike has a 40 spoke rear wheel as standard, you/we can retain the hub. The old spokes are then removed from the wheel. The kit has all the parts required to construct a wider wheel. So you just spokes and center it. Of course we can do that for you.
TÜV:
If the wheel is spoked and centered by us, then there is a TÜV parts certificate according to § 19.3.
(Not built-in spokes and / or rim without papers are delivered.)
Sizes: On request.
