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.

Feedback through the frameset is good, so if you are the kind of rider who wants to push on through the corners and take a few risks here and there, the 4S will keep you posted on what the tyres are up to beneath you.
On my usual test routes it handled well, and the position is comfortable which definitely pays dividends on longer rides. If I were to go back to daily, year-round commuting or focusing on long days out on the bike I'd definitely consider the 4S.
The latest version of the Kinesis 4S is a solid performer right across the board, offering versatility both on the tarmac and ever so slightly away from it if you want safe and predictable then it could well be the bike for you."
