Hope’s RX4 Flat Mount Disc Calipers Apr 17, 2019

While these aren’t necessarily a new product in Hope’s expansive line of brake calipers and components but it’s new to me. I didn’t get a chance to shoot the Hope booth at Sea Otter, but I did see these Rx4 brake calipers, compatible with SRAM and Shimano brake levers. Have you used these yet? Are they as amazing as their MTB brakes?
