I have been using the EVS RS7 for a few months now. There are a few things to note: These are really bulky braces. On long rides of single track trail(we are talking 40+ miles) the straps dig into my skin, and leave rashes and bruising. The RS7 braces offer lateral support, and some protection from hyperflextion, rather than side protection from being skewered by your kick starter. I have bad knees to start with so I can atest to the fact that wearing a brace is better than knee guards. Again for lateral support and hyper flex protection. I would reccomend going with a wrap around type knee brace if you are looking to protect your leg.
