Designed to match the Shimano GRX RX400 groupset, the GRX RX400 10-Speed STI Shift Levers & RX400 Calipers provide slick shifting and powerful braking in a sleek, stylish package that is perfect for your gravel or adventure bike.

  • Gravel inspired level and hood ergonomics for exceptional performance and comfort
  • Anti-slip brake lever improves control in all conditions
  • Provides smooth, fast and light-action shifting performance
  • Oversized 22mm pistons optimised for heat insulation, lightweight & stiffness
  • Increased pad to rotor clearance & inline hose routing for low profile design

The GRX RX400 levers get the look and feel of the higher end 11-speed levers, while sticking with 10-speed internals. As well as the specially designed hood shape to improve grip in wet and muddy conditions, the shifters also feature neat under-tape cable routing, keeping the front end of your bike looking neat and tidy. Like the more expensive GRX groups, the GRX RX400 levers provide a shorter shift stroke that delivers what Shimano calls ''lightest and easiest front shifting Shimano has ever made''. The lever is fully adjustable to accommodate different hand sizes via an easy to use reach adjustment. Braking isn't ignored of course, and the power and feel of the braking has been improved, especially when riding on the hoods. The GRX caliper offer excellent heat dissipation which means consistent braking power even on the longest or roughest descents. Providing slick shifting and powerful braking, the GRX RX400 STI Levers & Brake Calipers provide exceptional performance at a competitive price.
