Forwards Faster Further

Boardman bikes are more than just machines, they are a way of life. Founded by Chris Boardman, Olympic gold medallist and multiple World Champion.

Boardman bikes are built for all riders; from the enthusiast through to the everyday leisure cyclist. Boardman's range of bikes have been specifically designed to achieve unrivalled all-round performance with affordable value.

These bikes are developed by enthusiastic cyclists, who are out there every day.

Function and Fit

The SLR frameset is optimised for aerodynamic performance without adding weight or compromising the ride quality. Our wind-tunnel proven tube profiles minimise aerodynamic drag.

With a new C8 Carbon Endurance layup and 12 speed wireless shifting, the SLR 8.9 Disc Di2 adds two technologies previously reserved for the Boardman 9 Series bikes into the renowned for value 8 Series package.

Building on the already low weight and aerodynamically efficient SLR 8.9 Disc frame, Boardman have developed a brand new C8 Endurance carbon layup. It not only shaves over 150g from the frame and fork, but also adds a big increase in vibration damping through the frame and fork, making the SLR 8.9 Disc Di2 a surprisingly comfortable place to rack up miles.

Boardman's C8 Endurance Carbon fibre blend uses high-modulus fibres in key areas to reduce weight and dampen road vibrations. Deep, box-section chainstays, an oversized bottom bracket and dropped seat stays combine in a compact, stiff rear triangle, maximising power transfer.

Wireless Shfiting

The SLR 8.9 Di2 uses Shimano's latest 12 speed 105 Di2 groupset. Perfect shifts even under load with no inner cables means less maintainance and a more streamlined ride.

A 50/34t compact chainset combined with a 11-34t cassette offers a broad range of gears to cover off steep climbing, flat land cruising and fast descending.

The shifters communicate wirelessly with the derailleurs for a clean, uncluttered cockpit.

Quality and Value

The Shimano hydraulic brakes deliver fantastic stopping power and inspire confidence when you need it most. 28mm Vittoria Rubino Pro Graphene 2.0 tyres offer a blend of low rolling resistance, excellent cornering grip and strong puncture resistance. Tubeless ready lightweight alloy rims allow for an upgrade further down the line.

The Little Things That Matter

Working with Chris Boardman, data from hundreds of bike fits and insight from bike fit experts, we have made simple changes to the contact points of the SLR range.

Using advanced pressure mapping and real-world testing we've shown that the Boardman SLR saddle provides long-ride comfort. Bar width and crank length are also reduced vs previous bikes to make sure they are suited to the fit needs of real cyclists.

These changes also reduce the rider's frontal area, which has been wind tunnel tested to reduce drag, meaning less effort required for the same speed.
