Men Mountain Bottoms
What you wear on the bike changes once the terrain gets technical. Mountain bike bottoms are built around movement — the ability to stand, climb, corner aggressively, and slide back over the rear wheel without your shorts fighting you. That means roomier cuts, articulated panels at the knees, and waistbands designed to work with a pack or hip belt. Many riders layer a padded bib liner underneath; others prefer bib shorts with an outer shell aesthetic.
The men’s mountain bike bottoms at RA Cycles skew toward the premium end: Assos leads the selection with their Tactica line built specifically for trail riding, alongside Café du Cycliste, Yeti, Gore, and Pearl Izumi. The range covers MTB shorts, bib shorts, and riding pants — from warm-weather trail shorts to spring/fall bibs designed for cooler conditions. Sizes run from XS through 3XL.
