  • Boardman SLR 8.9 Carbon Road Bike in Blue Fade
Overview

The original SLR 8.9 Carbon was our most popular carbon road bike, and for good reason. We think the light, stiff and comfortable carbon frame designed with aerodynamic tube profiles and features is a perfect platform for all-round road riding, and the reviewers agreed with us. For most bike brands, 4.5 out of 5 reviews and comments like “Blimey, what a corker!” (road.cc) would be a reason to kick back and celebrate a job well done. However, at Boardman, we are always looking for ways we can push our bikes to the next level, and this is what we have done for the new SLR 8.9 Carbon.

One of the only criticisms we could level at the old bike was the 10 speed gears – functional, but a little heavy and unrefined. With that in mind, we’ve upgraded the shifting to Shimano’s 11 speed R7000 105. Offering smooth gear changes, reduced weight, ergonomic design and all the trickle-down technology from Shimano’s flagship Dura-Ace groupset, 105 is a fantastic performer.

Not only have we upgraded the bike’s gearing – but we’ve also worked with expert bike fitters to ensure the touchpoints on the bike are going to suit riders even better than before.

FRAMESET:

The new SLR 8.9c frame and fork use the same aerodynamic design and geometry as the top of the range SLR 9.6 and so delivers outstanding performance. The dropped seat stays and an integrated seat clamp help reduce drag and combine with carefully designed carbon fibre layup to deliver all day long comfort. This isn’t achieved at the expense of speed though. Using CFD and wind tunnel testing, our tube profiles deliver a significant aero boost compared to previous frames, and a stiff bottom bracket and light overall weight mean that the bike responds instantly when you put the power down. With clearance for up to 28mm tyres and hidden mudguard mounts, the SLR 8.9 Carbon can turn its hand to any type of road riding, whatever the weather.

CONTACT POINTS:

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 will provide long-ride comfort for the majority of people. Bar width and crank length are also reduced vs previous bikes to make sure they are suited to the fit needs of real cyclists, not just based on old traditions. 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.

HIGHLIGHTS:

Shimano 105 11 speed shifters and derailleurs ensure crisp and easy gear changes
A compact 50/34 chainset with 11-30 cassette offers a wide spread of gears for climbing and descending
Vittoria Zaffiro Pro Graphene 2.0 tyres combine great grip with puncture protection and low rolling resistance
Boardman SLR Wheels are tubeless-ready, so can be easily upgraded to run without tubes
Tektro R315 long drop brakes give clearance for up to 28mm tyres, or to run mudguards with 25mm

  • Boardman SLR 8.9 - 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."

  • 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 longterm upgrades." Read Article
