Easton Bottom Bracket

Bottom Brackets are an essential part of the bicycle that is often overlooked and forgotten, but Easton sees the BB as another opportunity for performance gains and improved efficiency. For their BB's they have developed a seal that achieves a very low level of drag while still retaining excellent protection qualities. Its thinner and low viscosity bearing grease with the correct fill level offers higher durability at high speeds. If you're running the best crankset on the market, you should have the performance BB to match.
