SPP SUPERSIZED™ HD 6061-T6 36/28 HOLE 20/15/10MM QUIETLY INSTANT DISC REAR HUBS
DESCRIPTION
SPP Quietly Instant Rear Hubs represent the highest level of drivetrain efficiency in the SPP ecosystem.
Built around a precision one-way bearing system, these hubs deliver true instant engagement with zero lag and near-silent operation. Unlike traditional pawl systems, the one-way bearing eliminates engagement delay and reduces internal drag, allowing for smoother power transfer and increased efficiency under load.
Machined from 7075-T6 aluminum, these hubs are engineered for maximum stiffness and minimal deflection, especially when paired with Supersized™ drivetrain components.
Available in both 15mm (28H) and 20mm (36H) configurations, these hubs define the next step in BMX drivetrain performance.
FEATURES
Zero-Lag Power Transfer
The one-way bearing engages immediately with pedal input, eliminating delay between crank movement and drivetrain response.
Continuous Contact Engagement
Unlike pawl systems, the engagement surface remains in constant contact, removing indexing gaps and smoothing power delivery.
Load Spread Across Bearing Surface
Torque is distributed across the full engagement surface rather than discrete contact points, reducing wear concentration.
Ultra-Smooth Pedal Feedback
Delivers a fluid, uninterrupted feel through the drivetrain, especially noticeable under high cadence and sprint transitions.
No Backlash Under Re-Engagement
Re-engagement after coasting occurs without play or lag, maintaining drivetrain precision through rhythm sections.
Reduced Mechanical Noise Signature
Operates without the clicking associated with pawl systems, resulting in a quieter and more refined ride experience.
High-Torque Stability Platform
Engineered to maintain structural and engagement stability under maximum sprint loads and high-power outputs.
Advanced System Positioning
Represents the highest-performance engagement system within the SPP lineup, designed for riders prioritizing efficiency and precision.
