Shimano GRX FC-RX610-1 HTII cranks

The FC-RX610 cranks offer all the features of the higher-end RX820 series, but also impress with their excellent price-performance ratio. Due to the slightly simpler choice of materials, they weigh a few grams more, but their stiffness and functionality are at the same high level. The workmanship is also of very high quality and tailored to the intended use, so the cranks will be your faithful companion for many kilometers.

Rooted in simplicity, reliability and adventure, the new 12-speed GRX kit provides more shifting options along with unrivaled ergonomics. So riders get the most out of every "non-asphalt" adventure, no matter where it is.
Product features
Optimal gear combination for different terrains and riding styles
The cranks are designed for 12-speed shifting systems.

SK Dobry den, na tomto Marine su osadene neznackove kluky. Je potrebne si pozriet aku hrubu os maju. Ak je 24mm tak mozete pouzit tieto kluky bez vymeny stredoveho zlozenia. Ale az pri montazi zistite ci nebude potrebne podlozit misky stredoveho zlozenia aby sa dali kluky dotiahnut bez vole a boli vycentrovane voci ramu.
