Shimano GRX RX610 2x12k WITHOUT BB

Two-piece cranks with a fixed axis designed for 12-speed systems. They ensure smaller jumps when shifting, which makes it possible to maintain rhythm and cadence.

Rooted in simplicity, reliability, and adventure, the new 12-speed GRX kit provides more shifting options along with unrivaled ergonomics. Thanks to this, riders get the most out of every "non-asphalt" adventure, no matter where it is.
