PRO Clip-On J-Bend 45 Alloy Extensions

The PRO Clip-On J-Bend 45 Alloy Extensions are aerodynamic clip-on extensions designed to deliver a stable, comfortable hand position with efficient airflow for sustained efforts. The 45° J-Bend with a 100mm rise supports a neutral wrist angle and slightly higher hand position, helping reduce strain while maintaining speed. A lightweight AL6061 alloy build keeps weight low without compromising strength, making them suitable for long-distance use across multiple bike setups.

Key Features and Benefits:

• 45° J-Bend with 100mm rise: This specific bend angle and rise position your hands slightly higher while keeping wrists neutral. This reduces pressure on joints and tendons during extended efforts. The outcome is improved comfort and sustained control when holding an aero position for longer periods.
• Neutral wrist positioning: The extension shape aligns your wrists in a natural angle rather than forcing rotation. This lowers fatigue in the forearms and hands. The result is more consistent power delivery and reduced discomfort over long rides.
• AL6061 alloy construction: The use of high-grade aluminium provides a strong yet lightweight structure. This ensures durability under repeated load without adding unnecessary weight. The outcome is reliable performance with minimal impact on overall bike weight.
• 350mm extension length: The extended reach allows precise adjustment of hand position to suit your fit. This supports better weight distribution and body alignment. The result is improved aerodynamic efficiency and stability across varied riding positions.
• 22.2mm clamping diameter compatibility: This standard diameter ensures seamless integration with PRO Clip-On Clamp systems and adjustable armpads. It also supports Shimano wired and wireless TT shifters. The outcome is straightforward setup with broad system compatibility.
• Multi-discipline versatility: Designed for TT and triathlon bikes as well as road, gravel, and mountain bikes, these extensions adapt to different riding styles. This allows you to maintain an aerodynamic position across multiple platforms. The result is consistent performance and comfort regardless of bike type.

Holding a stable aero position for extended periods depends on comfort, fit accuracy, and reduced strain. The 45° J-Bend profile combined with the 100mm rise supports a more natural wrist angle while keeping your upper body aligned. This reduces fatigue build-up and helps maintain steady output over longer distances. The lightweight alloy construction and adjustable reach further support a balanced, efficient riding position.

For riders refining their cockpit setup, these extensions provide a clear balance of comfort, compatibility, and aerodynamic function. Their adaptable design and low weight make them a practical upgrade for consistent performance across varied riding conditions.
