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 re-spoke & true it. Of course we can do that for you.
TÜV:
TÜV Approval as per § 19.3. is only issued where we build & true the wheel for you (not included in the kit). Otherwise the spokes & rim are supplied without papers.
