Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

Introducing the brand-new Kinesis 4S Tiagra, a modern aluminium road bike designed for those who seek a balance between speed and adventure. Kinesis UK has taken their 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 the 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.
