Product Description

Designed for rides on rough roads, through gravel and mud, so you can get comfortable and stress-free wherever you want to go and achieve that unique feeling of performance. The first group of components developed by Shimano for gravel rides. Instead of telling gravel riders what they need, Shimano developers asked them what they wanted. Shimano has listened for two years and spent countless hours talking to Gravel enthusiasts from around the world. They drove on dust and gravel roads and narrow tracks, crossed streams and mountain passes to imagine what a Shimano Gravel group could look like. The result of all these trips and also new friendships? First the Shimano Gravel Alliance and now the Shimano GRX - the world's first series with components designed specifically for gravel.

The goal is not to dominate the Gravel scene or change its direction. Shimano did not want to reinvent the wheel. The engineers at Shimano love Graveln as he is. Shimano simply wanted to give you and your friends the opportunity to ride the bike the way you want with a new group of components. And the GRX does just that.

And last but not least, the developers envisioned a Shimano GRX group that delivers top performance in gravel racing while offering options that make it affordable for cost-conscious drivers. By setting these design goals, Shimano has developed components that are also suitable for cyclocross, bike adventures and almost every similar type of bicycle diszplin. Simply put, the Shimano GRX is the world's best way to move freely and discover new territory on the Gravel bike.

The HG-EV cassette is used for gradation and cadence management adapted to the driver. Shimano offer the optimum gear ratio for 11-speed shifting systems. You can choose wider or narrower increments to suit your needs. With the HG-EV cassette, you get an 11-speed switching system without compromises in robustness and improved HYPERGLIDE switching function.

The concept of the HOLLOWTECH II technology was aimed at the production of an optimized crankset that minimizes the driver's effort for the drive. The high rigidity of the crankset ensures the efficiency of the power transmission when pedalling, while its low weight relieves the driver, especially over longer distances. The crankset was developed with a view to achieving an optimum ratio between stiffness and low weight. HOLLOWTECH technology allows extremely light, hollow crank arms to be produced using SHIMANO's exclusive forging technology to achieve maximum stiffness. In addition, with the HOLLOWTECH II crankset, the right crank is fixed to the bottom bracket axle, achieving an optimum balance between maximum rigidity and minimum weight. The external bottom bracket offers better weight distribution and stability for more efficient power transmission. The HOLLOWTECH II crankset has been designed with an optimum balance between stiffness and rotation efficiency as well as low weight and attractive appearance in mind.

High-quality precision seals
The HOLLOWTECH II crankset also features high quality precision seals in the bearing area to extend durability and maintain excellent rotation efficiency over time.
