The Shimano GRX ST-RX810-R is a right-hand hydraulic brake and 11-speed shifter combo specifically designed for gravel bikes with drop bar setups. It features an ergonomic, gravel-inspired design with an anti-slip textured brake lever to enhance grip and control on rough terrain. Constructed from durable aluminum, it integrates Shimano Road 11-speed drivetrain compatibility, providing reliable, light, and responsive shifting action commonly found in Shimano’s road components. Reach adjustment is available to fit various hand sizes, though adjustable contact point is not supported. The use of mineral oil hydraulic fluid ensures consistent braking performance. Weighing approximately 286 grams, this lever balances control and weight for mixed-terrain riders who need precise shifting and braking performance without excessive bulk. It pairs ideally with Shimano GRX or Road series components, making it well suited for gravel riding, adventure cycling, or any mixed-surface use where control and durability are priorities.
