The PRO Clip-On J-Bend 65 is an aerodynamic extension designed specifically for less flexible riders who require a higher, more upright hand position to maintain comfort in the aero tuck. Featuring a pronounced 65-degree J-Bend curve and a substantial 155-millimetre rise, it enables a neutral wrist position while reducing strain on the back and shoulders. Constructed from lightweight yet durable AL6061 aluminium, the extensions weigh 110 grams and offer a 360-millimetre reach. Their 22.2-millimetre clamping diameter ensures full compatibility with the PRO Clip-On Clamp and PRO Adjustable Armpads + Mount, as well as Shimano’s wired and wireless time-trial shifters. Suitable for TT and triathlon bikes, as well as endurance-focused road, gravel, and mountain bike setups, the PRO Clip-On J-Bend 65 creates a stable, ergonomic, and aerodynamic cockpit for long-distance performance.
