WOOdman HEADSET TECHNOLOGY
Designed for high performance across extreme use and lightweight riding. Tool-free installation.
Position Specific Bearings
For extreme use or light weight - the loads a headset has to cope with remain the same.In our Position Specific design we increase the number of balls in the bottom bearing to nearly 100% more than the competition. This, along with our full-grease spec, nearly doubles the lifespan of the lower bearing.
SGC Fork Crown Race
One of the key features of the SPG series is the SGC fork crown race- it can be assembled or removed without any tools.
Our patent SGC crown race allows it to be installed on the fork crown without tools, while the reinforced steel ring prevents deformation during the process. We also added a seal to ensure the least amount of maintenance possible.
