Proven on the World Stage. Built for Champions.
At the absolute apex of bike trials competition, there is zero margin for error. A single millimeter of brake slip or a fractions-of-a-second delay in lever snap can mean the difference between a clean section and a world championship title.
We don’t just design hardware for everyday riders—we engineer components that survive the brutal, explosive forces generated by the world’s most elite athletes. ξ /ksi/ cycling brakes are being trusted on the global stage by our championship-winning riders.
🥇 Jack Carthy – 26″ (UK)
Jack Carthy is famous for rewriting the rules of what is possible on a 26″ trials bike. To launch up massive vertical walls and gap across obstacles with absolute precision, Jack requires an unyielding, rock-solid wheel lock that feels like an extension of the frame itself.
🥇Alejandro Montalvo – 20″ (Spain)
Alejandro Montalvo dominates the highly technical, fast-paced 20″ world circuit. His riding style demands a bike that is incredibly agile and perfectly balanced—delivering instantaneous braking power precisely when needed so he can focus entirely on his lines.
Build Your Champion-Tier Setup
You don’t need a world championship license to ride the best hardware in the sport. Because our slave cylinders feature universal hybrid compatibility, you can upgrade your current setup with the exact same high-end components used by Jack and Alejandro.
