Best Knee Braces for the Price


These TLD knee braces have been incredible. They've saved me numerous times while riding. They're extremely durable and worth every cent that I paid. I would definitely recommend these to anyone who rides hard and wants great protection for their knees.


Lawrenceburg, IN


Just a great product by TroyLee


Love this brace! Just dont feel i´m using it! Amazing! For sure would buy it again!


Rio - Brazil




Came down hard on my right leg wearing these today, wasn't rocking the velcro pads as they fall out (the velcro was stuck to the box rather then on the brace when I got them) I thought I had torn a major ligament in my knee as when I put weight on it I could feel it popping to the right, however an x-ray showed no major damage so they seem to have done the job. The damage could be from lack of those pads holding it firm in place so watch them, have to go back to the docs in a couple days when the swellings gone down. I do think that I would have snapped my leg at the knee without them.




The most comfortable brace I have used


I have gone through a number of top brand braces over the year and each time they have been really uncomfortable, didnt fit right, broke on long rides etc. Luckily I managed to recoup a bit of money, but it has been an expensive learning curve. I now have the TLD Catalyst X braces, and without a doubt the most comfortable best fitting, no slipping braces I have owned. I rode a 2 hour race the other weekend and didnt even feel like I had braces on. Awesome product.




these are great all around knee brace


these are great all around knee brace had them for about 2 months now and cant say nothing really negative about them yet. at first they felt a little odd but after a few rides i wont ride without them. they don't rub or pinch and doesn't take up much room in your gear or boots.

Excellent Product


These knee braces are very comfortable, lightweight, and appear to be well made. They do not snag on the liner while putting on my MX pants. What amazed me the most is that I don't even notice them when I ride or even while walking around between motos. I highly recommend these knee braces.


Farmington, NM


Light weight and low profile, great deal


Was using a donjoy from a acl surgery on my left. Wanted a matching pair to protect my right as well. Decided on the Troy lee because it is constructed like the CTI of old and had the same hinge as the donjoy. The knee cup and brace eliminate shin knee guards that are bulking in the boot. Now the donjoy is very light and low profile, the troy lee is the same, very pleased. Be sure to follow the strap procedure and leave #5 for last and unhooked. The only negative would be plastic degree stops, jonjoy and other braces have cast aluminum or steel.


Suffolk, VA


TLD braces


I've been riding with the Fox knee and shin guards. These took a long time to get used to and still rubbed in some spots. I received the TLD Catalyst braces and put them on the first time at a practice session. The braces were immediately 100% more comfortable than the Fox guards. As a matter of fact just walking around getting the bike ready I forgot they were even there. Once on the bike these felt sooo much better than my old guards it was amazing. Fit was perfect for my measurements. The only thing I would have like to see included with the braces is instructions how to adjust the flexion and extension stops. BTW, my wife is a PT and was impressed with the quality, light weight and adjustability of these braces.
