With a layup featuring high strength resin and 100% unidirectional carbon fiber, BOX one trail rims provide increased impact resistance and durability in an extremely lightweight package. Each rim includes externally reinforced nipple seats that significantly decreases the likelihood of rim failure due to a spoke pulling through, and a flat seat for the valve that creates a positive seal between the valve lock ring and rim (so water and debris cannot enter the rim cavity). Optimized for tubeless systems using sealant, box one trail rims are fully compatible with traditional inner tubes as well. Lace them up to any 28-hole MTB hub of your choice.
