Easton Bottom Brackets have been developed for use in combination with the Easton EC90 SL crankset. It uses a new bearing seal and grease.
Typically with any bearing there is a tradeoff between protecting the bearing internals for longevity and bearing seal drag which impact efficiency. For this Bottom Bracket Easton developed a seal that achieves a very low level of seal drag while still retaining excellent protection qualities.
Easton took a new, thinner and low viscosity bearing grease and modified the percentage of grease fill to again find the perfect balance between durability and minimized running friction. A thinner grease, with the correct fill level, is more durable than a thicker grease when spinning at high speed.
