WOOdman HEADSET TECHNOLOGY

Designed for high performance in extreme conditions and lightweight riding.

FL CAP

FL Cap is a WOOdman lightweight design. The latest Torx screw is made of 7075 aluminum, which is lighter and has better torsinal strength than Haxagon socket screws.

Dust Cover

Our standard dust cover is 7mm, and most Axis SPG Series Headsets are available with an optional 20mm top bearing cover.

20mm Dust Cover Advantages:

1. Raises the stem height
2. Eliminates the need for multiple spacers
3. Looks better and weights less
4. Less stress on the steerer tube

SP Hight Adjustment Plate

Because all frames are not created equal, and paint thickness may vary, the dimension of the headtube may be different from frame to frame. In order to keep the smallest possible gap between the top of the head tube and the headset cap, which guarantees the best headset sealing possible, we designed the SP Height Adjustment Plate. By adding or removing SP plates during headset cap assembly, you can adjust the gaps height. Each WOOdman SP headset comes with three aluminum spacers.

Position Specific Headset Bearings

For the bike headset, the key and important element is the bearings! WOOdman bearings are sealed, with a retainer design for the top bearing and a full-ball and full-grease design for the bottom bearing. This meticulous design not only extends the lifespan of our bearings but also enhances their durability, enabling them to withstand even the most extreme riding conditions. As a result, they are the ideal choice for upgrading the headset bearing on road bikes or MTBs.

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.
