The Shimano Ultegra 6800 Bottom Bracket is an optimally designed bottom bracket for most bikes. This 68-millimeter bracket is 14 grams lighter than the previous version, the 6700. The integrated bottom bracket is made using Shimano's HollowTech II technology, allowing for wide bearing placement. This, in combination with a wider axle diameter than other bottom brackets, allows for increased stiffness and pedaling efficiency. The HollowTech II tech also utilizes special bearings to make sure everything rolls smoothly without losing durability.
