Product information

Alpinestars Fluid Tech Carbon Knee Guard Left. Made of a new, advanced carbon polymer compound for greater resistance and performance, the Fluid Tech knee guard reduces the risk of knee injuries by preventing excess torsion forces transmitted in the event of a fall. Thanks to its innovative design, the Fluid Tech is ultra-lightweight and affords a secure, high custom fit, whilst improving the directional articulation of the knee when riding.

  • Fluid Tech kneepads are EN 1621-1 (K type B) certified. They are extremely lightweight and resilient and are made from a new advanced high performance carbon polymer that maintains resistance and performance levels even at extreme temperatures.
  • With DEFT (Dynamic ErgoFit Tech) design that makes these kneepads a very light and ergonomic protection.
  • The innovative knee pivot system has a built-in polycentric hinge system for tool-free fast and easy pin stop change (0, 5, 10, 15 and 20 degrees) for preventing hyperextension injuries. Pin stops are included and provide postoperative support. Leg movement can be reduced from between 0 and 20°.
  • Ergonomically sculpted, ventilated knee cup in semi-rigid TPU for greater durability with high performance protective PU memory foam backing, affording exceptional impact protection.
  • Highly vented channelled padding and mesh areas for superb breathability.


  • Ergofit spacer kit (included). These spacers allow the regulation of knee width (1mm, 2mm and 3mm on both sides) affording a precise and fully custom fit. They have been anatomically optimised for improved directional articulation performance and position stability.
  • Elastic straps on the upper and lower parts of the knee cup ensure a correct positioning, allowing for multi-directional freedom of movement and preventing pressure points on the knee cap.
  • New and gentle double strap system provides a secure fit to the knee in all driving positions and includes a combination of buckle and Velcro® closures for fast and easy fitting.
  • With new side padding to avoid pressure points and to afford greater comfort.
