The Boardman SLR 8.9 Disc Di2 builds on the popular SLR platform with electronic shifting and enhanced comfort features, making it an excellent choice for riders who want speed without compromising long-ride enjoyment. The C8 Endurance Carbon frame is engineered using aero-optimised tube profiles to reduce drag while maintaining a low overall weight. Its carefully tuned carbon layup improves vibration damping, helping smooth rougher roads and reducing fatigue on longer outings.

Paired with the vC8 carbon fork, the SLR 8.9 Disc Di2 feels composed and efficient, with handling that remains predictable whether you're climbing, descending or covering steady miles on rolling terrain. The endurance geometry offers a balanced position—long enough for efficiency but upright enough for comfort.

Shimano’s latest 105 Di2 12-speed electronic groupset brings the benefits of crisp, consistent shifting without cable stretch or tuning worries. The wide-range 11-34 cassette, combined with a compact 50/34 chainset, provides gearing suited to both steep gradients and fast cruising. Braking is handled by Shimano 105 hydraulic discs, offering controlled stopping power whatever the weather.

Rolling on Boardman SLR Alloy Disc wheels, the bike is fitted with 28mm Vittoria Rubino Pro Graphene 2.0 tyres—known for their mix of grip, durability and low rolling resistance. These tyres help give the bike a smooth, efficient ride feel while remaining tough enough for year-round riding.

Boardman contact points have been refined using rider feedback and pressure-mapping, resulting in a comfortable SLR saddle and proportioned bar and crank lengths that suit real riders. The frame also includes hidden mudguard mounts, making the SLR 8.9 Disc Di2 a practical option for commuting and winter training.

The result is a bike that marries modern electronic performance with endurance-focused comfort—ideal for riders looking to elevate their road cycling experience with a dependable, versatile carbon platform.
