Profile Design Supersonic Ergo+ 35slc Extension

Mount a Supersonic Ergo+ 35slc Extension from the Profile Design brand on your triathlon bike or your time trial bike!

The Supersonic Extender (formerly known as J5) is the first and best model in the new generation of Profile Design mounts. It offers easier adjustments and a greater adjustment range than anything before it.

Pairing this support with the ergonomic armrest provides industry-leading adjustment options and greater comfort. With the 35c extensions, this aerobar is suitable for runners who want to adopt an aerodynamic arrowhead hand position.

35c extensions provide a 35 degree ski shape. This facilitates a slightly downward-rotated wrist position to create a simplified hand position. They are 400mm long and can be cut to fit almost any rider. They are drilled for rear output cable routing.
