  • Brand:Shimano

Mechanical shifting does not come better than it does with the Shimano Dura-Ace 9100 11-Speed Rear Derailleur SS. Ultra-smooth, durable and light thanks to a carbon construction, this derailleur redefines mechanical shifting performance.

Shimano has done a fantastic job of integrating carbon fibre parts into the derailleur's construction to both boost weight and enhance performance. The carbon cage combines with carbon fibre inner and outer pulley plates to enhance rigidity and strength.

Shimano has not cut any corners and have utilised pulleys constructed from DuPont's Zytel material for greater longevity and less chain noise. This means the SS design is compatible with ratios up to 30T; adding extra versatility for mountainous rides.

With Shimano's new Shadow design, this derailleur looks low profile and is incredibly light at just 166g, making it the perfect option for riders looking for optimal mechanical shifting performance.
