Add a tucked, aerodynamic position to your road, gravel or time-trial bike with the PRO Clip-On J-Bend 65 extensions. The pronounced 65-degree J-bend lifts your hands into a comfortable, neutral wrist position, helping less flexible riders hold an aero tuck for longer without strain.

Highlights

  • High 65-degree J-bend raises the hands for a comfortable, sustainable aero position
  • Neutral wrist angle reduces strain on long time-trial and endurance efforts
  • Lightweight AL6061 alloy extensions at just 110g the pair
  • Works with both wired and wireless Shimano TT shifters
  • Part of PRO's modular clip-on system for a tailored fit

Comfortable aero, made accessible

The defining feature of the J-Bend 65 is its tall, sweeping bend. With 155mm of rise and 360mm of reach, it brings the grips up and forward so you can settle into an aggressive tuck while keeping your wrists relaxed. It is an ideal choice if you want the speed of an aero position but find a flat or low extension uncomfortable to hold.

Light, durable alloy

Formed from AL6061 aluminium, these extensions are light at 110g per pair yet stand up to the demands of training and racing. The 22.2mm tube diameter is the industry standard for aero extensions, giving you flexibility when fitting shifters and accessories.

Built for shifting

The extensions are designed to accept both wired and wireless Shimano TT shifters, so you can run electronic Di2 control right at your fingertips in the tuck.
