Fenwick's: Marginal gains! Thats what its all about. Replace your existing grease in rotational cup & cone or cartridge bearings to remove wasted watts and reduce friction. Fenwick’s Professional High Speed Grease has a super low viscosity to improve bearing efficiency for race days. The 80ml tube negates the need for a specific grease gun, as it includes a pinpoint nozzle for accurate application and minimal wastage.
