WOOdman Headset Bearing

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.
