The 24685 is the professional alternative to heavy, old-fashioned clamp-on hubs. By utilizing a splined interface, the carrier is mechanically locked to the axle's rotation. This eliminates the risk of the brake hub spinning on the axle under heavy braking loads, ensuring that the driver has a firm, predictable brake pedal every time they enter a corner.
Detailed Technical Specifications
1. High-Tolerance Splined Interface
-
1.5" Precision Bore: Broached to exact tolerances to match 1.5" splined axles. This "zero-play" fit prevents the "clunking" and mechanical wear often seen in keyway-style hubs.
-
Axle Preservation: Unlike set-screw or clamp-style carriers that can scar or "burr" the axle surface, the splined design distributes braking torque evenly across the entire circumference of the axle.
-
Easy Positioning: Allows the racer to slide the brake assembly to the perfect lateral position for caliper alignment before locking it down.
2. Lightweight Billet Engineering
-
6061-T6 Aluminum: CNC-machined from solid billet for maximum structural integrity. The "spoke" design is engineered to shed every possible gram of weight without sacrificing the strength needed to handle high-heat braking cycles.
-
Reduced Rotating Mass: In the Junior Sprint class, reducing the weight of the rear axle assembly is the fastest way to improve acceleration and throttle response.
-
Heat Dissipation: The aluminum body acts as a heat sink, helping to pull warmth away from the brake rotor and preventing "brake fade" during long feature races.
3. Universal Compatibility
-
Standard Bolt Patterns: Designed to accept the most common lightweight racing rotors used in Junior Sprint and Micro Sprint racing.
-
Slim Profile: Engineered to provide maximum clearance for the brake caliper and nearby chassis bracing, even in the tight confines of a small-displacement racer.
