Boardman SLR 8.9c 105 Mens Road Bike

To celebrate the launch of the new range, Boardman have pushed the boat out and upgraded their most popular carbon road bike. Not only does the SLR 8.9c have a stunning paint fade finish but they’ve also upgraded the groupset to the smooth and light weight 11 Speed Shimano 105. The old bike scored 4.5 out of 5 in several magazine reviews with the only criticisms being for the 10 speed gears, so this new model markedly improves on what customers and critics told us was already a great package at a market beating price.

The New Boardman SLR 8.9c  Road Bike has exactly the same aero tube profiles and geometry as the top of the range SLR 9.6 and so comes with an excellent pedigree. Features such as the integrated seat clamp will reduce drag further and yet dropped seat stays underneath you and a full carbon fork both help with maintaining comfort. We’ve not forgotten that most of us ‘feel the need for speed’ though and a stiff bottom bracket area means that the bike responds instantly when you put the power down.  With respected components such as Vittoria Rubino Pro IV tyres you are assured of a bike that’s fast and agile enough to race, comfortable enough for longer days in the saddle and also brilliant Value for Money.
Boardman SLR 8.9c specifics:

  • Gears: 22 speed Shimano 105 and 11-30 cassette gives slick shifting over a wide range
  • Frame: Boardman carbon SLR frame with aero tube profiles
  • Forks: Full carbon forks for better comfort and weight saving
  • Brakes: Tektro R315 brakes for controlled and powerful stopping
  • Wheels: Boardman wheels and Vittoria's Zaffiro tyres keep you rolling

More About The New Boardman SLR 8.9c Road Bike

Slick and purposeful gears
Shimano 105 R7000 doesn’t just look great, it also performs brilliantly giving swift and sure shifting with a light touch. The integrated levers are ergonomically designed for general comfort with chamfered tops meaning your grip is assured even when it’s hot and sweaty. The 50-34 Chainring and 11-30 Cassette give a good range for UK and Irish conditions so there’s every reason to take on even the toughest of challenges.
Impressive Carbon frame and forks
The SLR 8.9c uses the same aero tube profiles and geometry as the top of the range SLR 9.6, with our C7 carbon being used in both frame and fork. The frame is designed to combine great stiffness and ride quality whilst the aero tube profiles give riders more speed for the same effort. Features such as the integrated seat clamp reduce drag, whilst dropped seat stays and the full carbon fork help maintain comfort. The stiff, oversized PF86 bottom bracket area means that the bikes responds instantly when you put the power down.

The little things that matter
With Chris Boardman as Chairman of the company, Boardman have a wealth of experience to draw on and are always looking at the fine details when developing bikes. Using data from hundreds of bike fits and insight from bike fit experts, they have made simple changes to the touch points of the bikes. They’ve worked to develop a range of saddles using advanced pressure mapping and real-world testing to make sure any saddle on a Boardman bike is going to suit the majority of people riding it. Bar width and crank length are also reduced for different frame sizes 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!
