Easton BB86 Bottom Bracket
This versatile bottom bracket is designed for reliable performance, whether you’re riding with your local road club or exploring backroads on your gravel bike. It comes equipped with a 41mm cup diameter and 86.5mm (BB86) shell compatibility for straightforward installation on your road bike. Easton has also kitted out this model with a Press Fit design to make installation quick and easy.
Bottom Brackets are an essential part of the bicycle that is often overlooked and forgotten, but Easton saw the BB as another opportunity for performance gains and improved efficiency. Easton has 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.
