CeramicSpeed OSPW Standard (Sram Force/Red AXS)

Unrivaled Efficiency.

The CeramicSpeed OSPW System is more than just an upgrade; it is a total transformation of your bike's drivetrain efficiency. Developed in collaboration with world-class aerodynamicists and professional athletes, this system is designed to save you between 2.4 and 4w (or more) compared to a standard stock setup. By reducing chain articulation angles and utilizing the world's most precise ceramic bearings, the OSPW system ensures that every ounce of your power reaches the rear wheel.

Whether you are chasing a podium on your Winspace SLC 5.0 or looking to perfect your dream build, the OSPW is the definitive standard in mechanical advantage.

Why the OSPW is the Professional Standard:

• Optimized Chain Path: The oversized 15T upper and 19T lower pulleys significantly reduce the "wrap angle" of the chain. This lower friction path minimizes internal chain link friction, providing a "free speed" sensation you can feel immediately.

• Hand-Built Ceramic Bearings: Every pulley wheel is equipped with CeramicSpeed’s Grade 3 Silicon Nitride balls, which are 400% smoother and 128% harder than steel. This results in a system that is not only faster but significantly more durable.

• Carbon Fiber Reinforced Cage: The bespoke cage is crafted from high-modulus carbon fiber, providing extreme lateral stiffness for crisp, snappy shifting while keeping the weight lower than most stock aluminum cages.

• Unmatched Longevity: CeramicSpeed bearings typically last 3 to 5 times longer than standard high-end steel bearings. This is a "set-it-and-forget-it" performance gain that pays dividends over thousands of kilometers.

• Bespoke Craftsmanship: Every OSPW system is hand-built in Denmark and tested to meet the most rigorous standards in cycling.

Technical Specifications:

• Pulley Material: Aluminum (standard)

• Bearing Type: CeramicSpeed Grade 3 Silicon Nitride

• Cage Material: Carbon Fiber Reinforced Polyamide

• Compatibility: 12Speed (Sram Force and Red AXS)

• Warranty: 4-year standard

The Alegro Verdict: The OSPW is the "crown jewel" of the drivetrain. While the watt savings are scientifically proven, the true magic is the silence. A drivetrain equipped with an OSPW and a high-quality wax (like Silca Super Secret) is hauntingly quiet. It represents the absolute pinnacle of what a mechanical bicycle can achieve.

Reduce Friction. Save Watts. Master the Road with CeramicSpeed.
