"What Our Gearhead® Experts Are Saying: ""I’ve swapped these onto a heavily used pair of knee guards, and it instantly brought them back to life. The new caps restore that solid, confidence-inspiring feel when things get rough, especially in rock gardens and bike park terrain. It’s a smart way to extend the life of pads you already trust."" Our knee pads take a beating season after season, absorbing hits so we can keep charging without hesitation. When those hard caps start showing their age, the Launch Pro D30 Knee Hard Caps are the easiest way to restore that original, bombproof feel. Built by Fox Racing, they’re designed to bring worn Launch Pro D30 pads back up to speed for another season of hard riding. Made from the same tough compound as the originals, these replacement caps deliver dependable impact resistance when casing landings, clipping rocks, or sliding out in loose corners. Simple to swap and built to last, they let us keep riding the pads we love instead of starting from scratch."
