YUNIPER ball bearing Nitro | 6904 2RS | 20 x 37 x 9 mm
The durability of hubs, bottom brackets and other moving parts depends largely on the quality of the ball bearings used. If the manufacturer has cut corners here, the fun will soon fall by the wayside.
The Yuniper ball bearings definitely belong to the high-quality category. A special surface treatment, black oxidation, is used to apply a special coating that significantly reduces the risk of corrosion. To prevent dirt and water from getting there in the first place, 2RS lip seals run on both sides of the bearing. A water-displacing grease is also used. Yuniper ball bearings are therefore ideally prepared for all areas of use.
