TriRig Signature Arm Cups

The TriRig Signature Arm Cups are, by TriRig's account, the most affordable arm cups the company has made. They are built from ThermoPlast, a material TriRig describes as ultra-strong and lightweight, and they are where TriRig starts for anyone who wants purpose-built triathlon or time trial arm cups without stepping up to the carbon models.

Adjustability is what TriRig stresses most. The Signature cups have additional mounting points and slotted bolt holes for an increased adjustment range, and TriRig calls them the most universal cups on the market. That matters if you are fitting them to an aerobar they were not designed around, or you are still working out your position.

Both versions use TriRig's textured neoprene pad, which TriRig intends to balance grip and cushion so you can stay in the aero position longer. The closed back adds support behind the elbow. It is intended for riders on high hands or an upward-tilt setup, where TriRig says the extra wrap keeps you locked in while your upper body relaxes. Closed back sets arrive with the pads pre-installed, and each version is also offered with a replacement pad set. For a rider who wants comfort and fit range in one cup, the Signature is the model built around exactly that.
