Gravel bikes are becoming increasingly popular among cyclists. The advantages are obvious. They have a more comfortable geometry than road bikes, are excellent off-road and are suitable for longer journeys. However, conventional road bike components reach their limits on these bikes. This is why Shimano has developed its own groupsets especially for this type of bike.
The GRX ST-RX600 shift/brake levers have the same grip geometry optimized for gravel bikes as the GRX ST-RX810 lever units. Compared to the high-end shift/brake levers, the weight is slightly higher and the servo wave technology is not on board.
Their upper humps have been raised to prevent you from slipping forward on rough surfaces. A recessed thumb recess ensures a firm grip on difficult terrain at all times. And to prevent your hands from sliding back and forth even when riding in the rain, a non-slip material has been selected which also has good damping properties and therefore increases comfort. As usual, the dual-control lever offers outstanding ergonomics. The crisp gear changes can be carried out quickly, precisely and with little finger force. This means you never lose control of your bike, even in hectic situations. The brake lever has also been designed so that you can stop quickly at any time from any grip position. It is slightly bent inwards and the axle of the lever has been moved upwards. This improves ergonomics and at the same time reduces the necessary hand force. In addition, the reach of the brake lever can be individually adjusted so that bikers with smaller hands can also ride safely.
The BR-RX400 flat-mount brake calliper improves braking performance and modulation under all conditions. Maintenance work, such as bleeding or changing pads, is also easy to carry out. The L03A brake pads with cooling fins help to keep brake temperatures low, especially on long descents.
