Out of Stock


The legend of Dura-Ace once again sets the industry standard.

Quite simply the best Shimano groupset available. A fine mix of carbon fibre, titanium and benchmark technology.

Since 1973, Shimano's Dura-Ace components have been at the forefront of pro racing and pro-level technology. Dura-Ace has continued its legacy of being proven in the peloton as well as serving as a launch pad for new technologies.

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.

  • Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load
  • Close ratio gearing allows a more efficient use of energy through finer cadence control
  • Largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity
  • 4 largest sprockets are made from titanium to reduce weight without sacrificing strength
  • Sprockets are extensively cut away and drilled to further reduce weight without reducing rigidity
  • Nickel-plated finish offers hard wearing resistance to corrosion
  • Alloy cassette lockring
  • For Super Narrow 10-speed HG chains
  • Weight 163 grams for 11-23 tooth
