Introducing the brand-new Kinesis 4S Tiagra, a modern aluminium road bike designed for those who seek a balance between speed and adventure. We've taken our acclaimed Kinesis R1 and worked hard to improve every detail to improve every ride.

The 4S Tiagra is built around the same proven frame and fork as our highly praised, group test-winning R1 bike which Cycling Plus magazine proclaimed had "Understated class and excellent ride quality" and BikeRadar.com said had “instant zing when pressing the pedals". The lightweight double-butted 6061 Alloy tube blend provides a responsive ride feel, and the impeccable weld quality and attention to detail ensure high standards. Additionally, the internal down tube cable routing keeps the bike clean and easy to service. It features a Shimano 2x10 drivetrain, offering a wide gear range suitable for diverse terrains. The 4S Tiagra also comes ready to ride with mudguards fitted, making it suitable for all seasons.

The custom full UD carbon fork reduces road buzz and offers precise handling, while the Kinesis Rider Fit Geometry ensures comfortable all-day rides. With four sizes to choose from, finding the perfect bike fit is made simple. Get ready to experience the perfect blend of performance and adventure with the Kinesis 4S Tiagra.
