S71806-LLB Enduro Stainless Steel Angular Contact Bike Bearing 30x42x7
Angular Contact (A/C) cartridge bearings are specifically designed for hubs. In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction, and minimize wear. Wheel play can be adjusted out of the hub, to giving a more stable wheel, making it easier to adjust disc brakes, while still spinning freely.
Stainless steel has 20% less load capacity than the 52100 chromium steel, used in most Enduro bearings, but with far superior corrosion resistance.
Load side on the Green seal, 5-10 lbs preload required
Typical Application: Bottom Bracket
