1 review

The latest improved Ultegra groupset replacing 6800 and dripping down the new 9000 Dura Ace improvements to Ultegra.

 

The R8000 Chainset

  • The HollowTech II 11-speed Ultegra chainset offers an ideal balance of light weight and stiffness, making it the perfect choice for both enthusiast and competitive riders
  • HollowGlide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex and hugely improves shift performance, even under high load
  • The chainring teeth have been developed to work in conjunction with 11-speed HG-EV chains for increased contact to provide greater efficiency and improved power transfer
  • Industry leading HollowTech II cold forged 4 arm hollow cranks have been evolved for maximum rigidity while reducing weight

The R8000 Rear Derailleur

  • Ultegra Shadow design rear derailleur with wide link design gives quick accurate shifts and excellent drivetrain efficiency
  • Sleek appearance with Low profile Shadow design construction reduces risk of damage in a crash

The R8000 brakes

  • Dual-pivot calliper brake with super SLR-EV design for quick linear response, increased rigidity and improved braking power
  • Must be used in conjunction with super SLR levers for correct leverage ratio
  • Enhanced brake arch proportions give a quicker linear response and increased power
  • Added clearance for compatibility with 28C tire size

The R8000 STI levers

  • Precision-engineered Ultegra STI levers with carbon levers offer powerful braking and effortless 11-speed shifting, making them the ideal choice for both enthusiast and competitive riders
  • Shift cables are routed under the bar tape: re-development and positioning of the internal mechanism in combination with Polymer coated cables have made this possible, providing faster, lighter and smoother shifting
