Shimano Dura-Ace 7900 10spd 11-21T Road Cassette

Product ID: 2004087

The Shimano Dura-Ace 7900 10-speed cassette is a performance-driven choice, originally released in 2008, that blends lightweight construction with precise, high-speed gearing. With a close-ratio 11–21T spread, it’s engineered for elite racers and fast-paced training rides where maintaining optimal cadence is key. Its slick and responsive gear changes offer efficient pedaling economy, especially on rolling terrain and criterium circuits.

Engineered for strength without excess weight, this cassette uses high-quality steel sprockets mounted on a machined alloy spider. Its precision ramping and tooth profiles deliver quick and quiet shifts across the 10-speed spectrum. Though part of an older generation, the 7900 cassette remains a benchmark in road-racing hardware, prized for its performance and weight efficiency.
