Shimano ST-R4020 Tiagra 11spd Mechanical Shift Hydraulic STI Lever - RH

Season:Core Range

Brand:Shimano

Code:STR4020R

What it helps you do

Ride with calm confidence. Brake firmly from the hoods. Shift quickly when the road kicks up. This Tiagra Dual Control lever puts smooth, powerful hydraulic braking and short, natural shifts where your hands rest. The result: more control, less fuss, and a ride that feels right.

Ride feel and control

The slim, ergonomic shape sits naturally under your hand. The hydraulic brake lever delivers strong, controllable stopping power with less effort—especially from the hood position. You get steady performance as the pads wear, thanks to the reservoir’s auto‑adjust for pad-to-rotor clearance. That means consistent feel and fewer surprises on long rides and fast descents.

Shifting that follows your hands

Shifts happen with a short, inward stroke that mirrors natural hand movement. The reduced shift distance makes changes faster and more precise. It’s simple: reach less, shift more reliably.

Fit and maintenance

Reach adjusters let you tune the lever position to suit your hands and gloves. The hydraulic system is designed for easy bleeding and cleaning. Use Shimano mineral oil only to keep everything working as intended.

Key Features:

  • Slim, ergonomic Tiagra Dual Control lever for hydraulic disc brakes
  • Ergonomic short shift arc with reduced inward shift stroke for rapid, precise changes
  • Hydraulic brake lever: powerful, controllable and consistent stopping with less effort (especially from the hood)
  • Hydraulic reservoir tank auto‑adjusts pad-to-rotor clearance to maintain braking performance during pad wear
  • Contains left hand 2‑speed ST‑R4020 STI lever
  • Tuneable reach adjusters
  • Easy bleed and clean hydraulic system (use Shimano mineral oil only)
  • Product Type: Gear Lever / Road & Drop Bar
  • Discipline: Road
  • Side: Right
  • Colour: Black
  • Size: 11‑Speed
  • Di2: No
  • Shift Mechanism: Mechanical

Ready to ride

This lever gives you predictable brakes and natural, confident shifts. Fit it, tune the reach, and go find a climb — you’ll feel the difference.
