SHIMANO GRX 810 groupset 1x11 | 11-42 teeth 175 mm 42 teeth - SPECIAL OFFER
With the GRX, Shimano launched the first gravel-specific groupset on the market. Since then, the range of applications and the range of gravel bikes has expanded significantly. Shimano has responded to this development by expanding the range of the GRX groupset. With 11 sprockets on the rear wheel and the option to choose between a 1x and 2x setup, you can adapt your drivetrain even better to your needs. You can get the GRX 810 complete groupset here at R2-Bike.com at an absolute top price. Simply buy, install and ride off.
Shift-|brake levers SHIMANO GRX ST-RX810-LA / ST-RX810-R + brake caliper BR-RX810 Flat Mount
The upper humps have been raised to prevent you from slipping forwards on rough surfaces, while 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 of the GRX series offers outstanding ergonomics. The crisp shifting operations 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 forces. The reach of the brake lever can also be individually adjusted so that bikers with smaller hands can also ride safely. The 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.
The left lever also gives you the option of operating a height-adjustable seat post. This means you can always position yourself optimally in any riding situation.
Brake rotor SHIMANO Deore XT / GRX Center Lock RT-MT800 | 160 mm + 160 mm
With Ice-Tech cooling technology, the RT-MT800 brake rotor ensures constant braking performance even on long descents. The brake rotor is characterized by a three-layer sandwich construction. The stainless steel flanks with an aluminum core offer significantly improved heat dissipation. This allows the temperature to be reduced by around 100 °C.
In addition, the FREEZA aluminum cooling fins reduce the system temperature by a further 50 °C due to their increased surface area. The increased heat dissipation means that smaller brake discs can be fitted than usual. The service life of the brake pad is also significantly extended.
As is typical for Shimano, the rotors are suitable for the Center-Lock mount, which enables quick and easy installation, provides a secure hold and ensures a clean and compact look. A lighter aluminum carrier saves a few grams of weight compared to the previous version.
Crank SHIMANO GRX FC-RX810-1 | 1x11-speed | 42 teeth | Q-factor 151 mm | crank arm length 175 mm
With its chainline of 51.1 mm, the GRX 1x crank creates space for wide tires in the frame and positions the chainring optimally to the 11-speed cassette. Nevertheless, the Q-factor has remained pleasantly narrow at 151 mm.In conjunction with the compatible Shimano 11-speed cassettes with 11-40 or 11-42 teeth, the GRX drivetrain gives you the option of choosing between a maximum range for the steepest ramps and a narrower gear ratio for flatter terrain.
Rear derailleur SHIMANO GRX RD-RX812 Shadow+| 1x11-speed
The RX812-SGS rear derailleur is specially designed for the GRX 1x11 drivetrain with Shimano's 11-42 cassettes. There is a risk of the chain jumping off the sprockets, especially on bumpy surfaces. Shimano Gravel rear 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 another. 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.
Cassette SHIMANO Deore XT cassette CS-M8000 | 11-speed 11-42 teeth
The XT 11-speed cassette impresses with its outstanding shifting performance, low weight and high wear resistance. With the wide 11-42 tooth gradation, it is specially designed for 1x11 and 2x11 drivetrains.
The intelligent mix of materials increases the service life while reducing the weight of the cassette. For example, the base body (spider), the lockring and the largest sprocket are made of aluminum to save weight. The remaining sprockets, on the other hand, are made of steel, which not only reduces wear, but also generates more rigidity so that the entire power can be converted into propulsion.
Chain SHIMANO Deore XT | Ultegra / GRX CN-HG701-11 | 116 links with chain lock
Thanks to the adapted geometry of the chain links, the directional Shimano HG710 chain guarantees outstanding shifting performance in every situation. Even mud and dirt have little chance of attack thanks to the sophisticated design.
In combination with SIL-TEC, Shimano's new surface coating, ultra-low friction is generated and system performance is improved thanks to the use of embedded fluorine particles. The coating also reduces wear, driving noise and sliding friction, is dirt-repellent and abrasion-resistant, which significantly increases the durability of components treated with SIL-TEC.
