Alpinestars unveils B2 Carbon Knee Brace

Alpinestars has entered the knee brace market with its B2 Carbon model.


The B2 Carbon Knee Brace reduces the risk and severity of knee injury by preventing excess torsional force transfer to the knee in the event of an accident. Constructed from an ultra‐lightweight carbon fiber composite, the B2’s innovative design provides protection while still allowing the full range of normal knee movement while riding.
