Whether we are mountain biking to gravel riding, wearing a bib liner can improve our comfort on the bike. The Rapha Trail Liner Bib Shorts are designed to go under our trail shorts and incorporate a chamois pad for comfort. The mesh leg panels provide airflow, and the stretchy design allows for enhanced freedom of movement. Two rear cargo pockets allow us to take along the ride essentials, and silicone leg grippers help to keep the bib liner from moving around as we ride.
