The Boardman SLR 8.9 Disc Di2 is not just a bike; it's a testament to innovation and comfort. The C8 Endurance Carbon frame, meticulously engineered for aerodynamic efficiency, not only reduces weight but also introduces enhanced vibration damping. This translates to a ride that is not just fast but remarkably comfortable.
The Shimano 105 Di2 12-speed groupset ensures seamless shifting across a broad range of gears, complemented by a close-spaced 11-34 tooth cassette. Paired with a 50-34 chainset, this setup provides ample versatility for varying terrains, from steep climbs to exhilarating descents.
The hydraulic disc brakes by Shimano 105 offer superior stopping power and control, especially during fast descents. The Boardman SLR Alloy Disc wheels, combined with Vittoria Rubino Pro Graphene 2.0 tyres, deliver excellent grip, puncture resistance, and quick rolling.
Beyond speed, this bike prioritizes rider comfort. The SLR saddle, designed in collaboration with Chris Boardman, ensures long-ride comfort through advanced pressure mapping. Contact point adjustments, including bar width and crank length, are tailored for real cyclists, enhancing comfort and reducing wind resistance.
