Rich Howlandwrote a review of Troy Lee Designs T-Bone Knee Guard on December 15, 2013
I have problems with knee pads putting unnecessary pressure on my knees, and making them uncomfortable while riding. This is especially true on my left knee which I had ACL surgery on in 2008. I am happy to say these Troy Lees don't give me any uncomfortable sensations while using them. I have tested them out on my downhill bike, also while out hiking and snowboarding. I like these pads because they slowly conform to your knee, making for more natural knee movement while still providing excellent knee protection. My mid-thigh size is 21 inches and I ordered the XL/XXL. If my thighs were any smaller I would go for the L/XL, but I am very happy with the XL/XXLs!
