GRX BR-RX810 + Di2 ST-RX815 Shimano disc brake set - safe braking and electronic shifting


The Shimano GRX BR-RX810 BR + Di2 ST-RX815 disc brake set (front + rear) helps to get more brake control on mixed terrain. The GRX BR-RX810 brake calipers with Ice Technology ensure perfect heat distribution. In addition, there is the simple one-way bleeding and the uncomplicated hose connection system. The design of the brake calipers is flat mount, which has been established in the Road bike sector for several years now.
The Shimano GRX Di2 ST-RX815 electronic shift/brake levers provide more grip and confidence on rough surfaces and descents. Their higher grip humps have a positive effect on hand position when riding Gravel. The ST-RX815's higher placed brake/shift lever axle increases braking power and reduces fatigue on long journeys.

Technology:

STI Dual Control
Shimano Total Integration (STI) means the combination of braking and shifting functions in one lever, which increases safety when riding. By refining the technology, it became possible to make shifting so smooth at the front and rear that they can be triggered with just one finger. Shimano calls such levers Dual Control Levers (DCL).

Digital Integrated Intelligence (Di2)
Di2 systems are the electronic shifting systems from Shimano. They are based on the SEIS, the Shimano Electronic Intelligent System, which takes over the index shifting function from the mechanical components, only via power cables or radio signals and not via a Bowden cable. Shifting is done by simply pressing a button. This has the advantage that no great effort is required, your concentration on the ride is not disturbed and operation is easy even with cold hands. In addition, the electronic gear changes are very fast and highly precise. There is also no risk of a defective circuit due to dirty cables or other problems. You can adjust individual settings via the E-Tube Project, such as adjusting the shifting speed, the number of shifting operations per button press or the Synchro or Semi-Synchro shifting function. Shimano offers an app for this purpose. Gear maintenance and firmware updates are also done via E-Tube, with the bike connected to a PC running the appropriate E-Tube software for more extensive workshop work.

Servo Wave
Shimano Servo Wave technology optimises the travel of your brake levers. During the braking process, the brake pads are guided quickly to the brake rotor with very short lever travel. The greater part of the lever travel is reserved for the actual braking force. In this way, you can apply your braking power in a more targeted manner and use it more effectively.

One Way Bleeding
One Way Bleeding is a technique used on Shimano calipers that facilitates brake bleeding. The hose routing has been optimised so that no air bubbles remain in the brake calliper. In combination with the funnel, the brake can be bled cleanly and easily.

Bremskörper wie Ultegra, die aktuellen Bremsbeläge sind spürbar besser als die Vorgänger. Die STI bringen im direkten Vergleich zu den Dura Ace einen deutlichen Performancegewinn im Gelände. Das Bremsen in den Hoods ist spürbar erleichtert, die Bremskraft in der Handhaltung besser zur Wirkung zu bringen. Die Griffe liegen definierter in den Händen, gerade im ruppigen Gelände ein wesentlicher Vorteil gegenüber den hübschen aber eben auch sehr kleinen Hebeln der Rennradgruppen. Für Cyclocross und Gravel aber auch für Tourenrennradfahrer die mehr in den Hoods als in Unterlenkerposition fahren eine absolute Umrüstempfehlung.
