Shimano GRX FC-RX810-1 crankset - 1x11-speed for mixed terrain

The Shimano GRX FC-RX810-1 crank offers you optimal performance on mixed surfaces and riding styles. Narrower gear increments allow you to keep the pedal rhythm on any terrain. A chainline further out ensures compatibility with wider tyres. The single chainring features Shimano's Dynamic Chain Engagement technology so you don't have to worry about the chain dropping. Of course, the FC-RX810-1 crankset is also based on the Hollowtech II system, which has been tried and tested for years.

Lightweight cranks reduce the total weight of the bike and above all the rotating mass which is decisive for acceleration. The challenge is to reduce the weight of the cranks without compromising stability and load capacity. Shimano's state-of-the-art forging technology offers an ideal solution with the Hollowtech cranks. Just like a high-quality frame tube, the hollow crank arm is extremely stable and resilient at a very low weight.

Hollowtech II
Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.

Die Kurbel sieht und fühlt sich sehr hochwertig an, wirkt auch bei hohen Belastungen stabil und geräuschfrei. Nach mittlerweile über einem Jahr Benutzung habe ich keinerlei negative Aspekte gefunden - würde ich definitiv wieder kaufen.

Stabil und entsprechend etwas schwerer. Einfache Montage. Kein Knirschen oder Knacken.
