Easton BB Cinch BSA 68mm AM

Easton bottom brackets were developed for use in combination with the new Easton EC90 SL crankset.
The internal testing procedure at Easton included the development of a 24-hour continuous water invasion test, where essentially water flowed continuously into the side of the rotating bearings for a whole day.
They then used a new, thinner bearing grease with lower viscosity and modified the percentage of grease filling to find the perfect balance between durability and minimized running friction again.
