Instant Stopping Power: Super Pocket Bike Hydraulic Kit

Mechanic's Note: Most entry-level pocket bikes use mechanical calipers that fade under heat. Performance Benefit: Switching to a hydraulic system like this one provides a "linear" braking feel that doesn't stretch or go soft during long sessions. Pro Tip: Before mounting, verify your Caliper Bolt Spacing—if your fork uses a 43mm or 60mm mount, you will need a Caliper Adapter Bracket to complete the install!
