Transcending the lines between a road and gravel bike, the Roadrunner really could be either, but in fact offers the geometry and componentry to excel in both disciplines. A light frame brings the overall bike weight down to allow you to hold a faster pace on the road than a gravel bike, while the 35mm tyre clearance and capable geometry means it wont feel phased by access roads or singletrack.



SRAM Force 1 11 speed groupset keeps the overall weight down, utilising carbon crank arms and brake levers. An 11-42 cassette provides plenty of options on any gradient, while a narrow-wide chainring will keep the chain on and means noise will be kept to a minimum. SRAM Force hydraulic brakes provide a powerful bite but with plenty of control offered too.



Rapid Red 900 wheelset provided by Fulcrum feature a deeper aeroydynamic rim to assist you at higher speeds, while also remaining compliant for pot holes and rougher surfaces. They're also tubeless compatible too should you want to convert them.
