About this model
Our flagship steel frame is as popular as ever, and the original superbike is now even better! Used as a commuter by some, fast tourer or winter trainer by others, its inherent versatility makes it ideal if you don't have space for a stable of bikes. The disc mounts are placed inside the rear triangle to ensure the bicycle can be used with pannier bags and mudguards. Custom drawn and shaped tube sections used at the seat stays create a responsive frame that minimises rider fatigue and maintains ride quality. The latest model uses lighter and smoother, custom-shaped Columbus Spirit tubing. This responsive triple-butted steel is lively and exciting to ride, whatever the weather.
