SHIMANO GRX rear derailleur RD-RX812 Shadow+ | 1x11-speed
Gravel bikes are becoming increasingly popular among cyclists. The advantages are obvious. They have a more comfortable geometry than road bikes, are excellent off the beaten track 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 gear groups especially for this type of bike.
Especially on bumpy surfaces, there is a risk of the chain jumping off the sprockets. Shimano gravel derailleurs can prevent this from happening. A built-in stabilizer reliably prevents chain slap and keeps everything in place. This can also be switched off when riding on asphalt roads.
As you would expect from Shimano, shifting is quick and precise with little finger force. Even under adverse conditions, the chain shifts reliably from one sprocket to the next. In order to be able to adjust the rear derailleur optimally, it has its own adjustment screw on which the tension of the Bowden cable can be set.
Thanks to the compact Shadow design, the rear derailleur sits closer to the frame. This slim low-profile design not only cuts a fine figure visually, but also protects the rear derailleur from damage or branches reaching into the path in the event of a fall.
