Shiny Bikes :: Bottom Brackets :: Shimano Dura Ace Double Bottom Bracket

Shimano Dura Ace Double Bottom Bracket

Three words have emerged as the theme for the new Dura Ace system: Speed, Smooth and Strength. Speed and Smooth leads to effortless shifting, improved braking operation, and enhanced ergonomics. Strength is focused on the critical need for light weight without sacrificing rigidity, durability or precision. Dura Ace incorporates high-precision mechanisms that provide amazingly sensitive controlled response and excellent power transfer efficiency. Advanced low-mass designs reduce weight while still delivering the absolute dependability that racers demand. The Dura-Ace advantage has been proven on great road courses of the world.
