SPP SUPERSIZED™ Cold Forged HD 6061-T 31.8mm Stem with Heat Treated Chromoly Hardware
The SPP Supersized™ 31.8 Stem is engineered to maximize the performance of today’s oversized handlebar standard. By increasing the interface between the stem and bar, SPP enhances rigidity where it matters most—reducing twist and improving front-end response under race conditions.
Using the Supersized™ design approach, material is strategically shifted to reinforce the clamp zone while maintaining optimal weight. This creates a stronger, more stable connection that resists flex during sprinting, gate starts, and aggressive cornering.
The result is improved power transfer and steering precision, allowing riders to maintain control and efficiency at high speeds. Built for modern race setups, the 31.8 platform delivers a proven balance of strength, stiffness, and responsiveness.
