TR37 + Project 321

Designed and tested on the World Cup circuit, the TR37 is right at home chasing podiums at your local enduro or crushing a quick after-work lap with pals. Features a Lifetime Warranty.

The second generation of Project 321’s hub offers improved reliability, decreased drag and the same unique signature configuration with magnet-operated pawls. Pairing these hubs to a set of our TR37 rims will result in a reliable and instant performance upgrade for your bike.
