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.

Shimano Tiagra ST-R4020 mechanical shift hydraulic STI lever in Black

Season:All Year Round

Brand:Shimano

Code:ST-R4020STI

The Shimano Tiagra 2x11s Dual Control Lever brings advanced ergonomics from the renowned Shimano 105 series to a refined design for confident road performance. Developed through research on diverse hand shapes, the updated lever position and bracket design ensure comfort and control for road cyclists. The premium lever feel, reliable stopping power of hydraulic disc brakes, and smooth, intuitive shifting define the Tiagra 2x11-speed system, delivering precision and confidence for road cycling.

The slim, ergonomically designed dual control lever for hydraulic disc brakes offers powerful braking and effortless 11-speed shifting. An ergonomic short shift arc follows natural hand movement with an inward shift stroke distance reduced for rapid and precise gear changes. The hydraulic brake lever provides controllable and consistent stopping power with less effort, especially from the hood position. A hydraulic reservoir tank provides pad-to-rotor clearance auto-adjust, maintaining braking performance during pad wear.
