Add a little bit of stability to that pesky knee with the Troy Lee Designs 870 Knee Stabilizer. Built in cooperation with the fine folks at Shock Doctor, it adds compression and stability, adding some protection to your knee to reduce the risk of further injury. The 870 Knee Stabilizer is the stripped down alternative to Troy Lee's more protective 875 Ultra Knee Support. It forgoes the dual lateral hinges, and opts instead for flexible side stabilizers. The cutout in the knee provides compression and support for your patella, and N Tex fabric blends moisture wicking properties with heat retention, providing therapeutic heat that enhances joint mobility. And the antimicrobial treatment keeps bacterial growth at bay, so it won't turn into a petri dish just because you skip a wash or two. Granted, this isn't an alternative to knee surgery, and it can't prevent all injuries. However, if you're dealing with a nagging injury that doesn't warrant surgical intervention, this knee stabilizer can be exactly what you need to ride with less pain and fewer injuries.The Troy Lee Designs 870 Knee Stabilizer is available in five sizes, from Small, to XX Large, and in the color Blackgray. Please note: The 870 Knee Stabilizer is sold individually.
