 Leatt C-Frame Knee Brace

The Leatt C-Frame Knee Brace is an entirely new approach to further help prevent knee injuries for motorcycle, ATV and snowmobilers. No knee brace can prevent all foreseeable knee injuries but Leatt laboratory engineers and other medical professionals have come up with a radical departure in design to help further reduce injuries over what traditional cage type knee brace designs can do.

The C-Frame is based on three point force distribution, and has a super stiff C-arm mono hinge design for maximum force control. Having a single hinge, mounted towards the outside of the rider’s knee, means the rider can better grip the bike with the inside of their knee that is closer to the bike than other designs allow. A comfortable, low profile shin bone plate replaces traditional arms for better comfort and better rotation control. This plate also allows rider with larger calf muscles to wear a knee brace for the first time. InteliLink hinge with double pivot points, BioLink hinge ligaments and sealed bearings inside better replicate natural knee motion and have a very long lifespan. Vented upper leg plates eliminate the narrowly focused sideways forces on the soft tissues of the thigh. This increases sideways bending of the knee as well as helps reduce rotational forces. It also allows for better fitment on more shapes/sizes of legs without the need for expensive custom molds.

Leatt engineers also placed a comfortable CE impact certified protector onto a moisture wicking knee brace sock that is worn with the brace. This absorbs far more impact energy than traditional cups and better insures the knee protection is where it belongs.

Leatt C-Frame Knee Brace 4 5 1 1
As Reviewed on Newtonsride - great stuff This is the first knee brace that I have ever used and it is the first version of a Leatt Knee Brace they have made. I selected this brace for two reasons. 1 - I like the fact that they leave the inside of your knee free so you can feel the tank 2 - It's Leatt. They know protection. When I got the knee brace I was really excited - but then really confused. The brace looked a lot like it had already been used. Leatt Knee Brace with scratches out of the box I didn't return the brace to Revzilla where I had bought it, as I was leaving the next day and really wanted to try the brace out. I did however call them to see if perhaps it had been a returned unit. It was not a previously returned item. When they saw they pictures they gave me a partial refund once they knew that I didn't want to return it. Revzilla is the best place to buy Moto equipment in my opinion. The braces themselves were awesome. They are highly configurable so the event fit on my tree trunk legs. I rode with them for an 8 hour freeway day - then a couple of days up in the hills. I did not feel them on ... ever. They are super light anyway - but the lack of frame on the inner thigh allows you great contact with the bike. The result effect is that you don't even notice them. They made the fit of my AlpineStars Tech 10's a little bit difficult as my calfs are thick and they already put the Tech 10's to test. However they all fit together well. I was riding with no armor above the waist and having these on definitely instilled confidence, and at the same time made me feel like my elbows and shoulders were at risk. My only request (given the large calfs) would be slightly longer straps for the calf guards. Overall - this product gets 4 gears. January 5, 2015
