A 100 Series Alpha Aluminium frame with advanced tube shaping for high-end looks and ride quality, a 10-speed Shimano Tiagra drivetrain, powerful disc brakes for all-weather stopping, super-durable wheels, integrated frame mounts for carrying additional gear, 32 mm tubeless-ready road tyres for added cushion and flared handlebars for extra control and stability.
Why you'll love it
- A totally versatile and smooth ride that's a perfect choice for your first performance road bike

- Internal cable routing and an integrated cockpit provides premium looks and a clean aesthetic
