Alpinestars SX-1 PLASMA Cross Enduro Knee Protector Black Red Grey

The SX-1 PLASMA Knee Protector features a PLASMA Knee Protector integrated into a highly ventilated, semi-rigid construction for superior impact protection, while the Integrated Dual Gear System (DGS) promotes natural knee articulation.

Technical Data Sheet:

Main Features:

• Highly Comfortable: The Nucleon PLASMA Knee Protector is made of USDA-certified bio-based viscoelastic material. Designed for multi-directional flexibility, the protector molds to the knee for a snug fit, effectively dissipating impact energy to provide reliable protection.
• Dual Density Co-Injected Chassis for Unparalleled Support and Comfort: Designed with a hollowed-out lower rand made from a soft polymer blend to prevent pressure points associated with a hard edge that occur when the boot pushes against the protector. The same hollowed-out design is also applied to the upper rand, preventing the protector from digging into the skin and causing discomfort while riding.
• Controlled Natural Motion: Featuring the Dual Gear System (DGS) where both the upper and lower frames have integrated gear profiles that ensure a smooth hinge function to promote natural knee articulation.
• Ergonomic Frames with Versatile Sizes: The SX-1 PLASMA Knee Protector’s ergonomically sculpted frames feature strategically placed over-injected rigid and flexible shells, providing a secure yet adaptable fit for a wide range of leg sizes.
• Patellar System Protection: The Patellar System is designed to provide full coverage of the knee cup regardless of the degree of extension while the rigid outer shell of the Patellar System prevents injuries from handlebar strikes.

Construction:

• Lightweight knee protection with wide protective coverage.
• The upper and lower frames are constructed from a high-performance polymer for optimized levels of flexibility and strength, as well as excellent weight-saving properties.
• The double pivot hinge system integrated into the upper and lower frames follows the natural movement of the knee and keeps the protector well positioned while riding.
• The frames feature a slim ergonomic design.
• The double strap closure system features a hook-and-loop closure with snap buckles for easy on and off and a secure, customized fit.
