Shimano Dura Ace 9100 Chainset

  • The HollowTech II 11-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite riders

Dura Ace Chainset

Will eventually be fitted to summer bike so not yet ridden, beautiful quality and usual excellent service from Vanilla Bikes

Shimano Dura Ace 9100 compact chainset

Good price and quick delivery from Vanilla bikes - will use again no doubt.
Bought to replace/as an alternative chainrings for current DA 9100 52-36 semi-compact set. Also 170 cranks to try them out vs my current 172.5
Not much else to say, quality product.
