Control, comfort, and Bernard Kerr&';s signature touch Developed with the creators of the Unno bike brand, the AMS RISE set a new benchmark for mountain-bike grips. Designed in Barcelona, it blends precision and all-day comfort for riders who demand total connection with their bike. The AMS X BK Bernard Kerr Signature RISE Grip takes that platform and gives it a distinctive identity, with a custom BK lock collar and a Sand colorway that stands apart from typical gravity grips. Bernard chose the RISE because it delivers the balance he wants: control, support, and confidence when the riding gets fast and rough. Its micro-diamond texture ensures confident traction in every condition, while ribbed pads and internal ribs add cushioning and control where it matters most. Finished in the unique Sand marbled tone with the custom BK collar, this signature edition brings together race credibility, proven performance, and a strong visual identity.
