The PRO Clip-On Carbon Ergo is an aerodynamic extension designed for flexible to moderately flexible riders seeking maximum comfort and efficiency in an aero position. Constructed from T700 carbon, it pairs a 45-degree bend with a flattened ergonomic hand section and a moderate 115-millimetre rise, making it suitable for a wide range of riding styles and body positions. At 105 grams, the extensions are lightweight, and their 400-millimetre length can be trimmed for a personalized reach. With a 22.2-millimetre clamping diameter, the PRO Clip-On Carbon Ergo is fully compatible with the PRO Clip-On Clamp and PRO Adjustable Armpads + Mount, as well as Shimano’s wired and wireless time trial shifters. It can be integrated into triathlon/TT bikes or used to build an efficient endurance cockpit on road, gravel, or mountain bikes.
