SHIMANO GRX ST-RX400 Brake/Shift Lever Combination 2x10 Speed with BR-RX400 Disc Brake Caliper (Front or Rear)

Explore beyond!
Discover the almost endless possibilities of modern road cycling with SHIMANO GRX components. The RX400 Series is Shimano’s entry into their range of gravel- and cross-dedicated GRX groupsets.

The GRX ST-RX400 STI shift/brake levers with gravel-specific ergonomics are your control unit for maximum shifting performance and outstanding control on rough terrain. Featuring an 18mm higher axis point than “traditional” SHIMANO road shifters, a curved brake lever profile and an anti-slip textured finish, the levers offer best grip on rough gravel roads and challenging cyclocross rides. Yet, the GRX levers also impress with high comfort and reliability on bikepacking adventures with lots of luggage and on daily commutes to work.
In combination with a powerful hydraulic BR-RX400 Flatmount disc brake, SHIMANO offers you a braking system with great braking performance and comfortable braking power modulation. This provides high safety when riding your gravel bike in bad weather. Fast and precise shifting and a wide lever reach adjustment range top off the package.
