TriRig Carbon Arm Cups

The TriRig Carbon Arm Cups are TriRig's longer carbon arm cups. At a total length of over 200mm, they are intended for riders who want more support under the forearm than the shorter Mini cups give, and TriRig describes them as building on the success of its Mini Open Back cups. TriRig says the carbon is durable and lightweight.

Both versions use TriRig's textured neoprene pad for grip and cushion. The open back is intended for riders who want a balance of aerodynamics and comfort over long distances, and its pads come pre-installed. The closed back adds substantial arm wrap and extends behind the elbow. TriRig says that gives it more surface area than any other production arm cups, and it is intended for high hands or upward-tilt aero positions, where the added support is meant to keep you locked in while your upper body relaxes.

TriRig's reasoning for both versions is the same: the more comfortable you are, the longer you can hold the aero position. The Carbon cups are for triathletes and time trial riders who spend long hours on the bars and want a longer platform than the Mini offers. Each version is offered with a replacement pad set, and a closed back or open back can be chosen to suit your hand position.
