The Shimano Tiagra SL-4703 shifters are the ideal solution for equipping your flat bar road bike with a reliable and high-performance 3x10-speed drivetrain. Belonging to the Tiagra 4700 series from the 2016 model year, these shifters bring to flat bar road bikes the Rapidfire Plus technology proven since 1985 on mountain bikes, combined with an optical gear display and advanced features inherited from Shimano's high-end groupsets.

Rapidfire Plus Technology and Intuitive Shifting

• Rapidfire Plus: allows you to downshift up to 3 gears in a single lever stroke, for fast and smooth gear changes on climbs or accelerations.
• 2-Way Release: cable release in two directions — pull with the index finger or push with the thumb — for maximum ergonomics and accessibility in all situations.
• Instant Release (right lever): instant cable release for even faster shifting at the rear derailleur, an exclusive technology of Tiagra 10-speed groupsets.
• Optical Gear Display: optical display window that shows the engaged gear in real time, ideal for anticipating gear changes and optimizing efficiency.

Robust Design and Road-Focused Ergonomics

• Painted aluminum lever body: rigidity and lightness for a contained weight of 510 grams per pair, cables included.
• Aluminum, resin and steel levers: hybrid construction combining strength, durability and comfort in hand.
• Ergonomic shape: designed to fit perfectly on Ø 22.2 mm flat bars, with precise shifting feedback and distinct clicks for optimal control.
• Integrated cable tension adjustment: fine-tuning of indexing without disassembly, directly at the handlebar.
• Clamp mounting: simple and secure installation on all standard flat bars.

Compatibility and Tiagra 4700/4703 System Integration

Warning: due to a specific cable pull ratio for the Tiagra 4700 series from the 2016 model year, these SL-4703 shifters are exclusively compatible with the following derailleurs:

• Front derailleur: Shimano Tiagra FD-4703 triple only.
• Rear derailleur: Shimano Tiagra RD-4700 or RD-4700GS (medium or long cage) 10-speed only.
