Closed Back High Side EVO Arm Cups: Maximum Containment for Ultimate Stability

The TriRig Closed Back High Side EVO Arm Cups are built for athletes who want the most secure and supportive aero position possible. Constructed from carbon fiber and formed with an ergonomic 3D-tapered profile, these cups provide a locked-in feel with a high-wall design that cradles the arms for unmatched stability.

With a fully closed-back shape, the EVO cups increase surface contact and containment, helping prevent arm drift and reduce fatigue during long efforts in the aero position. The medium-snug 95mm arc diameter delivers a comfortable yet supportive fit for a wide range of riders. At 625 grams per pair, they offer exceptional rigidity and support while maintaining a race-ready weight.

Designed for precise fit customization, the Closed Back High Side EVO Arm Cups feature a versatile 3×5 bolt hole pattern with elongated mounting slots for maximum adjustability. This allows riders to fine-tune reach, width, and arm positioning to suit both aggressive race setups and comfort-focused endurance configurations. Their carbon fiber construction ensures long-term durability while maintaining a sleek, low-profile appearance.

The Closed Back High Side EVO Arm Cups provide a major ergonomic upgrade for riders seeking superior arm containment, improved fit adjustability, and a more confident aero position—so you can stay stable, comfortable, and focused when performance matters most.
