Reviews & Ratings

The reviewer discusses the Shimano GRX RX610 shifter and RX400 brake as part of a gravel bike build. He notes that the 1x12s version is not available, so he recommends the 2x12s version, which requires using both shifters even though only one is needed, leaving the left lever as a dummy. He mentions that the Shimano shifter has a slightly better tactile feel and shifting quality compared to alternatives, but it costs more. He also comments on the durability of Shimano shifters, noting that they can develop play over time if not maintained, particularly the clutch mechanism.
