Alpinestars - A-Line Knee/Shin Protector (Bicycle)

Looking for a lightweight, high performance lower leg protector? Make a bee line for Alpinestars' A-Line Knee & Shin Guard. Specifically designed for Downhill, the A-Line's tough outer PP shell is backed by soft Biofoam padding for extra comfort.


In a serious pickle between which knee and lower leg protector to choose from? Start investigating the Alpinestars – A-line Knee/Shin Protector. This high-end performance knee/shin guard is specifically designed for Downhill Mountain biking and BMX to provide protection against rocks, shrubs, footpegs, and the occasional low hanging tree branch. Although it is designed for Downhill and BMX, this top of the line Alpinestars – A-Line Knee/Shin protector is also a candidate to be a competing accessory for the motocross protective gear Alpinestars has to offer. This is just one of many BMX accessories and mountain bike accessories that Alpinestars offers to their customers, but what separates the Alpinestars – A-Line Knee/Shin Protector from the rest is that it has guards that are engineered to have a streamlined and asymmetrical profile for a perfect fit. Key features of this highly-flexible mountain bike gear consists of a multi-material knee and shin guard constructed of a durable poly-fabric foam to increase impact protection, a 3D stretch mesh to ensure a snug fit, ventilation system that makes it breathable yet sturdy, and a soft inner Biofoam padding for unbelievable comfort. Along with the outer 3D stretch mesh, the Alpinestars – A-Line Knee/Shin Protector is equipped with a triple Velcro system that ensures you will receive a customized fit that is securely fastened to your body. If the stretch mesh and Velcro system is not enough for you, this strategically manufactured BMX gear and mountain bike gear is lined with a silicone printed inner knee sleeve to ensure that this Alpinestars – A-Line Knee/Shin Protector will not budge on the most demanding trails you can ride.



  • Highly flexible, multi-material knee and shin guard constructed from durable poly-fabric outer, breathable laminated impact foam and 3D stretch mesh.

    Comments about Alpinestars - A-Line Knee/Shin Protector (Bicycle):

    Got them on sale, and they are good for that 24% off. But not sure if I would be as happy if I paid full price.
