What Our Gearhead(R) Experts Are Saying: "When I want knee protection that doesn't slow me down, I grab the Speed Pro Knee Guards. The slim design stays put thanks to the silicone cuffs, and the D3O(R) impact protection provides confidence without bulk. Perfect for long days on the trail."We demand knee protection that moves with us, not against us. The Troy Lee Designs Speed Pro Knee Guards provide CE Level 1 impact protection in a lightweight, pedal-friendly design, so we can focus on the ride ahead. The D3O(R) Diablo(TM) insert absorbs impacts without sacrificing flexibility, while TLD Air Channels on the back panel enhance airflow to keep us cool. A silicone-infused cuff at the top and bottom ensures these guards stay put, even during all-out sprints and technical descents. With a slim, contoured fit that disappears under riding pants, the Speed Pro Knee Guards are our go-to for trail and enduro adventures.
