This results in superior modulation and a predictable, linear braking curve, allowing you to feather your speed with surgical precision. The caliper´s arms work in a coordinated, tweezer-like motion, applying balanced pressure to the rim for smooth, powerful, and consistent stopping power in all conditions. This advanced Rim Brake system ensures that your control is absolute, whether you´re navigating a technical criterium or scrubbing speed on a high-speed mountain pass.The main features of this caliper are centered on performance and compatibility. The direct-mount design increases overall rigidity and braking power by attaching directly to the frame, eliminating the flex associated with traditional center-bolt brakes. This solid foundation enhances the direct feel at the lever. The caliper also features an adjustable toe-in on the brake shoes, allowing for fine-tuned setup to eliminate squeal and maximize performance. Built for the modern road bike, it offers generous clearance for wider tires up to 28C and is compatible with contemporary rim widths from 20.8mm to 28mm, ensuring you can run the latest wheel and tire combinations for improved comfort and grip without sacrificing braking performance.
