What works well
Typically it’s hard for me to find knee braces that fit correctly. My knees fall somewhere in between size Medium and Large. This is where the Alpinestars Fluid Pro Knee Braces are perfect. They are easily adjustable to fit sizes Small through Large and any size in between (or XL to XXL for bigger guys) by adding the supplied ErgoFit spacers. To swap the spacers all you need to do is remove an allen bolt with the supplied allen wrench. The supplied directions do a great job of walking you through the process.
It is very nice to be able to custom fit a knee brace that you don’t need a prescription for. The Alpinestars Fluid Pro knee braces are very lightweight and the frame is flexible, which isn’t very common for knee braces. On top of the simple adjustability, the flexibility seems to aid in allowing the brace to form to your leg. The removable washable liner features built in ventilation that helps airflow while you ride. They are low profile compared to most knee braces and fit very well under almost any mx pant. All of these features create a brace that is as comfortable as anything else on the market.
The Alpinestars Fluid Pro knee braces come with hyperextension lockouts ranging from 0° to 20°. Changing the hyperextension lockouts is very simple, to remove the one that’s in place, push the little tab with a screwdriver and slide it out. To replace a hyperextension lockout with a different one no tools are necessary, all you have to do is slide it into place.
The knee cups are designed to follow your knee providing coverage when your knee is straight and bent. When your knee is fully bent, plastic shields that are attached to the liner protect areas that would typically be exposed. The coverage provided by the Alpinestars Fluid Pro Knee Braces is second to none.

What can be improved
The first thing that came to mind as a potential improvement is the fact that two of the straps are quick release and two aren’t. Why not just make all four quick release? Next, I may have chicken legs, but I can’t seem to keep them from sliding down on or off the track. A quality issue I noticed is that the elastic strap (the Alpinestars Fluid Pro has elastic straps that run from the top and bottom of each knee cup and are designed to hold the knee cup in place) that runs from the bottom of the left knee cup wore out after only 5 hours of use. An odd issue I’m having, that I have never had before is the insides of my knees bruising from gripping my bike when wearing the Alpinestars Fluid Pro. The last thing, that seems to be the norm with most motocross protective gear, is that it would be nice if the padding was beefed up, especially in the knee cup.
Final Thoughts on the Alpinestars Fluid Pro Knee Brace
The Alpinestars Fluid Pro Knee Braces may not be perfect, but I have never had a knee brace that was. The adjustability and flexibility are very nice features that help make the Alpinestars Fluid Pro Knee Brace a solid choice, especially if you’re in between sizes.
