We hate to break it to you, but your knees will definitely come in contact with the ground at some time on the trails -- it's a given. Investing in a pair of Rage Hard Knee Guards is a great way to avoid buying boxes of bandages after every ride, and they're lightweight and flexible enough that they won't slow you down on the days you happen to stay upright. The Rage Hards position a protective cap and EVA foam cushioning over the patella to help absorb impact if -- or rather, when things get a little crazy. The trade-off for added cushioning is a sacrifice in pedaling mobility, but we think it's a small price to pay, especially on the downhills. Six Six One constructs the back of the guard out of stretchy, moisture-wicking mesh to lessen bunching while you pedal and to promote ventilation. Expect the knee guards to have a contoured shape overall that won't move around once you've pulled them on and secured them with the hook-and-loop straps.
