In 1921 Shozaburo Shimano began production of his first bicycle freewheel. Since then, Shimano have gone from strength to strength and are now the largest bicycle component manufacturer in the world! Shimano innovations include: the first Freehub, Dura-Ace DI2 electronic groupsets, the SPD Clipless pedal and the Hollowtech crank and bottom bracket systems. Shimano components have been used by teams and riders including Lance Armstrong, Mark Cavendish, Team HTC-Highroad and Team Sky.
Created by definitive Shimano engineering and the latest technology, the new 7900 series Dura-Ace mechanical road group provides the ideal synergy of lightweight, durability and overall performance.
The increased accuracy, smoothness and reliability of electronic shifting makes gear changes faster and eliminates missed shifts.
The Dual control lever, HOLLOWGLIDE outer chainring and the new chain are adopted for an advanced shifting performance.
A no-nonsense, reliable, durable and excellent performing group.
