The SLR 8.9 Carbon uses the same aero tube profiles and geometry as the top of the range SLR 9.8, using our C7 Carbon in the frame and fork. The brand new frame has been designed to combine the fantastic stiffness and ride quality of the old Road Team Carbon with much more aerodynamic tube profiles to give riders an increase in speed for the same effort. Features such as the integrated seat clamp reduce drag further, whilst dropped seat stays and a full carbon fork both help with maintaining comfort. A stiff, oversized PF86 bottom bracket area means that the bike responds instantly when you put the power down. Mudguard mounts and clearance for 28mm tyres add practicality for year round riding or commuting too.
A quality frame needs quality components to compliment it, and we’ve chosen Shimano’s 2 x 11 speed 105 groupset, our own tubeless ready wheels and Vittoria Rubino tyres, offering an extremely competitive package that’s fast and agile enough to race but comfortable enough for long days in the saddle.
Occasionally, without notice, manufacturers change product design and/or specifications.
