Shimano Dura Ace bottom bracket

A silky-smooth ride and even better seals characterise the new Dura Ace bottom bracket. The Dura Ace bottom bracket cups for the Shimano Dura Ace Hollowtech II crankset. The new bottom bracket design is characterised above all by its low weight, low Q-factor and greater ankle clearance. Furthermore, it is easy and safe to install and guarantees a longer service life thanks to the larger bearing diameters.
