Clip-On, J-Bend 45, Alloy, Extensions Only

The PRO Clip-On J-Bend 45 is an aerodynamic extension engineered for moderately flexible riders seeking a comfortable, efficient, and neutral wrist position in the aero tuck. Featuring a 45-degree J-Bend curve and a 100-millimetre rise, it supports a slightly higher and more ergonomic hand position without compromising aerodynamic performance. Constructed from durable AL6061 aluminium, the extensions weigh just 97 grams and offer a 350-millimetre reach. With a 22.2-millimetre clamping diameter, they are fully compatible with the PRO Clip-On Clamp and PRO Adjustable Armpads + Mount, as well as Shimano’s wired and wireless time-trial shifters. Suitable for both dedicated TT/triathlon bikes and endurance-focused setups on road, gravel, or mountain bikes, the PRO Clip-On J-Bend 45 provides adaptable aerodynamic performance for long-distance comfort.
