Shimano Ultegra R8170 Di2 Disc Groupset – 160/140 mm Rotors

Performance meets value in Shimano’s latest Ultegra R8170 Di2 — the groupset that redefines what’s possible for modern road bikes. Sharing the same cutting-edge 12-speed Di2 platform as Dura-Ace, Ultegra delivers race-ready performance with a focus on all-day reliability and smooth, confident control.

With wireless shifting, refined ergonomics, and enhanced hydraulic braking, every shift is instant and every stop assured. The redesigned drivetrain reduces friction and noise while improving chain retention and efficiency, so you can focus on the ride — not the gear changes.

Matched with 160 mm front and 140 mm rear rotors, this setup offers perfectly balanced braking power and modulation across all conditions. Ultegra R8170 Di2 brings pro-level performance to every ride, whether you’re chasing a personal best or just chasing the horizon.

Key Features:

  • 12-speed Di2 wireless shifting for seamless, precise gear changes

  • Refined lever shape for improved comfort and control

  • Hollowtech II crankset for an ideal stiffness-to-weight ratio

  • Optimised 160 mm / 140 mm rotors for confident braking in any condition
