The Easton BB Cinch 30mm BSA 68 / 73mm bottom bracket

Easton bottom brackets are designed for use with their new Easton EC90 SL crank. Bottom brackets are an integral part of the bike, which is often overlooked and forgotten. However, Easton has also seen the bottom bracket as another way to increase performance and improve efficiency. Typically, with each bearing, there is a trade-off between the longevity of the bearing inner parts and the bearing seal resistance which compromises efficiency. For their new bottom bracket, they have developed a seal that achieves very low seal resistance while offering excellent protection qualities. Their internal testing process involved the development of a continuous 24-hour water invasion test that essentially poured water into the side of the bearings for a full day. And her new poetry proved excellent. By combining these results with extensive in-field testing, they are confident that the seals will perform better and increase the durability of the entire bottom bracket system. A new thinner and thinner bearing grease is also used and the percentage of grease fill has been modified to regain the perfect balance between durability and minimized running friction. Easten has found that a thinner grease with the correct level is more durable than a thicker grease when rotated at high speed. A lubricant that is thicker under centrifugal force would be thrown onto the outer bearing ring, where it would stick at lower speeds and not return to the inner race, making it prone to increased operating temperatures and higher wear.
