Shimano Dura-Ace 7900 10 Speed Road Cassette

Super lightweight 10-speed cassette with a rigid alloy carrier for excellent shifting even under the most demanding gear changes. Featuring four titanium cogs, the new Dura-Ace 7900 cogset has further improved shifting quality by creating a more rigid aluminum carrier unit along with a re-engineered tooth profile. Shimano also successfully reduced the weight of the rear wheel assembly by 10 grams.

Features:

  • 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

Specifications:

  • Sprocket Carrier: Alloy
  • Number of Sprockets: 10-speed
  • Sprocket Material: Steel/titanium
  • Chain Compatibility: Super Narrow HG for 10-speed
  • Weight: 163g (11-23T)
