About This

• UPGRADE YOUR RIDE Upgrade your ride with the Juin Tech F1 Cable-Actuated Hydraulic Disc Brake Caliper Set. If you ride a modern Road, Gravel, or Cyclocross bike and want the smooth, powerful feel of hydraulic brakes without replacing your expensive mechanical STI levers, the F1 is your perfect solution. HOW IT WORKS The Juin Tech F1 utilizes a closed hydraulic system actuated by a standard mechanical brake cable. When you pull your brake lever, the cable pulls a lever on the caliper, compressing the internal mineral oil and pushing dual pistons simultaneously against the rotor. This results in phenomenal stopping power, superior modulation, and even pad wear. WHY CHOOSE THE F1? Cost-Effective Upgrade: Keep your current mechanical drop-bar levers and shifters. A massive upgrade over standard mechanical disc brakes like the TRP Spyre or Avid BB5/BB7 Road. Sleek Flat Mount Design: Engineered specifically for the Flat Mount standard found on modern drop-bar bicycles, offering a clean and aerodynamic look. Maintenance-Free Installation: The closed system comes pre-bled with mineral oil. No messy bleeding kits or complex procedures required during installation. PRODUCT SPECIFICATIONS Model: Juin Tech F1 Brake Type: Cable-Actuated Hydraulic Disc Mount Type: Flat Mount Piston: Dual-Piston System Fluid: Mineral Oil (Pre-bled) Weight: Approx. 142g per caliper Compatibility: Road, Gravel, CX (Flat Mount frames and forks only) NOTE Please verify that your bicycle frame and fork use the Flat Mount standard before purchasing. This caliper will not fit Post Mount or IS mount frames without specific adapters.
