Designed using the same aerodynamic principles and geometry as the flagship SLR 9.6, the frame delivers a blend of speed, comfort and efficiency suited to a wide range of road riding.The carbon frame uses dropped seat stays, an integrated seat clamp and aero-optimised tube shapes developed through wind tunnel testing. These details help reduce drag while maintaining a comfortable, stable ride feel on longer outings. The carbon lay-up is tuned to offer stiffness where it supports power transfer, while absorbing road buzz to help reduce fatigue. The endurance-influenced geometry strikes a balance between an efficient riding position and everyday comfort, making the bike suitable for long training rides, steady group rides and weekend loops. Clearance for 28mm tyres and hidden mudguard mounts add welcome versatility.Shimano’s R7000 105 groupset is a key improvement over previous versions of the bike. With 2×11 gearing, improved ergonomics and smoother shifting, it brings technology inspired by Shimano’s higher-tier groupsets. The compact 50/34 chainset paired with the 11–30 cassette offers a broad spread of gears, helping you spin up climbs while keeping enough top end for faster sections. Shimano 105 levers pair with Tektro R315 long-drop rim brakes, offering balanced stopping power and space for larger tyres or a mudguard setup.The bike rolls on tubeless-ready alloy rims, providing an easy path to a tubeless upgrade for riders seeking extra comfort and puncture protection. Vittoria Zaffiro Pro tyres offer reliable grip and low rolling resistance, well suited to year-round training and varied road conditions.Contact points have been refined using rider data and real-world testing led by Chris Boardman. The updated saddle, shorter crank lengths and practical bar widths support a comfortable and efficient position, while helping to reduce frontal area for improved aerodynamics.Light, responsive and confidence inspiring, the SLR 8.9 105 is a great choice for riders stepping up to carbon, building fitness or wanting a fast, capable bike for regular road miles.
