PRO Clip-On S-Bend 30 Alloy Extensions

The PRO Clip-On S-Bend 30 Alloy Extensions provide a lightweight and aerodynamic cockpit upgrade that supports a low, efficient riding position for time trials, triathlons, and long-distance efforts. The 30-degree S-Bend shape and 80mm rise position your hands to reduce drag while maintaining control, helping you hold a consistent aerodynamic posture over extended rides. Built from AL6061 alloy, the extensions balance low weight with structural strength, making them suitable for both race and endurance setups across multiple bike types.

Key Features and Benefits:

• 30-degree S-Bend extension profile: The defined S-Bend shape positions your wrists and forearms in a natural alignment that supports a low aerodynamic posture. This reduces upper body strain while maintaining stability, allowing you to hold an efficient position for longer periods without loss of control.
• 80mm shallow rise design: The moderate rise lifts the hand position slightly to fine-tune fit without compromising aerodynamics. This creates a balanced cockpit setup that supports comfort while maintaining a streamlined frontal profile over long distances.
• AL6061 alloy construction: The use of high-grade aluminium delivers a strong and fatigue-resistant structure while keeping weight to just 92.5g. This ensures long-term durability and consistent performance without adding unnecessary mass to the front end of the bike.
• 345mm extension reach: The extended length provides ample adjustment range for precise rider positioning. This allows you to optimise your fit for power transfer and aerodynamic efficiency, resulting in improved consistency during sustained efforts.
• 22.2mm clamping diameter compatibility: The standard clamp size ensures seamless integration with PRO Clip-On Clamp systems and Shimano time trial shifters. This simplifies setup and ensures reliable control when shifting under load.
• Multi-discipline compatibility: Designed for TT and triathlon bikes, with the flexibility to fit road, gravel, and mountain bikes. This allows you to adapt your setup for aerodynamic gains across different riding styles and conditions.

A stable and efficient aerodynamic position is key when maintaining speed over long distances. The S-Bend profile works with the 80mm rise to support a controlled upper body posture, reducing unnecessary movement and helping you sustain power output. The lightweight alloy construction keeps the cockpit responsive, while the extended reach allows accurate positioning that aligns with your flexibility and riding style.

This setup gives you a practical way to refine your cockpit for improved efficiency and control. It integrates cleanly with existing PRO components and Shimano shifters, making it a straightforward upgrade for riders looking to improve aerodynamics and long-distance performance.
