Men Triathlon Bottoms

Men’s triathlon bottoms at RA Cycles covers the full range of race-day lower-body wear — from standalone tri shorts and run shorts to full one-piece trisuits and speedsuits. Every product in this collection is designed with the demands of triathlon in mind: quick-drying fabrics, minimal chamois construction that works on the bike and the run, and streamlined fits that don’t slow you down in the water or on the course.

The collection spans brands including Assos, Orca, 2XU, Cervelo, and more. Whether you prefer the flexibility of a separate tri short or the aero efficiency of a full skinsuit, you’ll find options at multiple price points suited to training days and race day alike.

About Men's Triathlon Bottoms

Triathlon-specific bottoms differ from cycling shorts in a few key ways: the chamois is thinner and designed not to retain water during the swim, the fabric dries quickly, and the fit is streamlined for the run. One-piece trisuits and speedsuits offer the advantage of a single garment for the entire race, eliminating a top change in T1. For shorter races like sprint and Olympic distance, a trisuit is often the fastest choice; for long-course events, some athletes prefer the flexibility of separates.

Assos tops the lineup with the Triator speedsuit for riders who want a premium race-day garment. Orca offers tri shorts at multiple price points through their RS1 and Core lines. The 2XU Dark Shield trisuit and Cervelo Ego 2.0 skinsuit round out the one-piece options, while Oomph! speedsuits and Asics run shorts give athletes more choices for race formats and budgets.
