No -- we're not saying you should take the line around the lofty booter, but rather, toss on the right armor before you give it a go. That's what Troy Lee Designs built the 6400 Knee Brace for, after all. At first glance you might think they look like simple neoprene sleeves with a little padding, but these braces take protection to the next level, with bilateral support hinges that fight rotational blows, while molded termoplastic protects from hits on your patella, thigh, and shin. The brace is designed with targeted padding that does its best not to hinder movement on the bike, while offering protection in the event of a crash. It features upper and lower compression straps with Hypalon pull tabs that offer excellent grip when fitting, so you can get things dialed just right.
