For the last 5 years we have been using SKF Bike Specific Bearings on our hubsets and now they are avalible to the public for upgrading your hubs or frame. The engineers at SKF designed custom specifications for standard size bearings to optimise thier performance and durability when used in the unique conditions encountered by mountain and road bikes. Due to the lower RPM and harsh conditions encontered on bicycles, standard bearings designed for high speed machinery just are not suitable. We asked the engineers to create a custom designed bearing with optimised seals, higher grease fill and clearances perfect for bike use.

• Custom sealing for ultimate durability
• Extremely high grease fill for longer lifespan
• SKF waterproof greaase installed at the factory
• Optimised tolerances and clearances
• Precision sub-micron graded balls
  
• SKF ultra high performance bearing steels for the balls and races
