GRX BL-RS717-L Hydraulic Disc Brake Left (Lever Only)
$205.00
The Shimano GRX BL-RS717-L is a left-hand hydraulic disc brake lever without integrated shifting electronics. It pairs with the GRX ST-RX715 Di2 right Dual Control lever, creating a mixed setup that reduces weight and complexity on the left side while maintaining matching ergonomics and lever shape across the handlebar.
Reach-Adjust allows riders to customize lever position to match their hand size and riding preferences. Eliminating the shifting electronics reduces weight relative to a full Dual Control lever, making this a practical choice for riders who want a lighter left-hand option without changing their overall cockpit setup.
