Troy Lee Designs built the Ultra Knee Support to provide added protection for those suffering with knee-related injuries. Built with input from the sports medicine gurus at Shock Doctor, it maintains the range of motion you need for pedaling, while protecting against lateral loads, as well as hyperextension. After all, there's nothing like riding when it comes time for recovery. Like most athletic knee protection, the Ultra Knee Support makes use of two dual hinges, which reduce side loading and lateral movement. As you already know, this type of protection is essential for protecting damaged ligaments from further injury. Additionally, the hinge locks at 180 degrees, to protect against hyperextension. The N-Tex fabric wicks moisture away from the skin and retains enough warmth to provide therapeutic heat, which is essential for retaining freedom of motion in swollen joints. The X-Fit lower strap is designed to provide a fine-tuned fit. Additionally, it benefits from an antimicrobial treatment, which helps to ensure that it doesn't get too funky in between washes. But if you're going to do it anyway, you may as well take precautions to minimize the chance of further injury, and the Ultra Knee does precisely that.
