For riders seeking an affordable carbon road bike with performance to match, the Boardman SLR 8.9 Carbon delivers speed, efficiency and versatility mile after mile. Significant component upgrades complement the already impressive frameset, resulting in a bike that punches well above its price point.
Aerodynamic Carbon Frameset Built for Speed
The SLR 8.9 Carbon centres around a responsive C7 carbon frame and fork that soak up vibrations and slice through the wind with ease. Aero tube shaping reduces drag, allowing you to maintain momentum on fast group rides and solo efforts. The balanced geometry provides a comfortable yet performance-focused position.
Upgraded Shimano 105 Drivetrain
A highlight for this model year is the move to an 11-speed Shimano 105 groupset. This provides closer gear ratios for maintaining cadence across rolling terrain as well as a lower climbing gear to conquer steep pitches. Ergonomic shifter design allows easy access across the wide cassette range.

From the refined carbon layup to the rider contact point adjustments, the SLR 8.9 Carbon is honed for all-day comfort without sacrificing speed. The 28mm tubeless-ready wheels and tyres further enhance compliance so you can log long miles in comfort. Rack mounts add utility for bikepacking adventures and commutes.

Reviews:
Boardman SLR 8.9 Carbon - Road.cc: "The Boardman SLR 8.9 Carbon retains its excellent frameset for 2021, but it's now bedecked with an even better groupset for a wider, 11-gear spread. It only boosts the already great versatility, and it's ripe for long-term upgrades."
Boardman SLR 8.9 Carbon - Cycling Plus: "There’s no doubt that the SLR offers one of the smoothest rides of any bike at this price – one of the advantages of carbon fibre, of course. You never feel that you are wanting for any stiffness, and there’s little obvious flex when you’re out of the saddle and cranking up the gears, but with long rides over potholed roads you never feel battered – a compliment to the redesigned Boardman saddle and the frame."
Verdict: "Retains the crown for best-value bike, despite the £100 increase." - Cycling Plus Magazine August 2021
