TriRig Mini Arm Cups

The TriRig Mini Arm Cups are the compact, adaptable end of TriRig's arm cup range. The closed back version measures 127mm long, well short of the 200mm-plus TriRig quotes for its Carbon cups. Adjustable slotted holes let them work with all versions of TriRig's aerobars, and TriRig says they are also compatible with most other bars on the market.

That makes them the practical choice if you are improving comfort on a cockpit you already own rather than building a new one around the cups. TriRig designs the Mini cups with an expansive surface area, increased arm wrap for stability and a textured, perforated neoprene pad it describes as super-grippy, all aimed at keeping you settled in the aero position for longer.

The open back is the original Mini design. The closed back builds on it with what TriRig calls a patented closed-back shape, and TriRig says it gives the most arm wrap and surface area of any arm cup on the market. Both versions are intended for triathlon and time trial bikes, and each is offered with a replacement pad set. If you are fitting a cup to a bar from another brand, or you want the shortest cup in this group, this is the model TriRig builds for that job.
