Knox SPS / Palm Sliders

Here from Social media? This is what our post alluded to:

Breaking your Scaphoid can result in loosing usability of your thumb. Fractures can, at best, take between 6 and 12 weeks to heal with casting. Some of these fractures can, however, take 6 months or more in a cast, and some may not heal at all. The scaphoid has an unusual internal circulation pattern. It receives its blood supply primarily from its far end or distal pole. Knox SPS (Palm Sliders) help prevent breaking, or fracturing of the Scaphoid.

In 2004 we started selling our Scaphoid Protection System (SPS) technology to glove manufacturers; So when Knox took up the gauntlet to create our own glove range which became known as hand armour we had the technology in place from the start to eliminate Scaphoid and hyperextension injury.

What are palm sliders? SPS?

Knox SPS (Scaphoid Protection Systemworks by adding two ‘skids’ [sliders] to the palm of the glove, one of which covers the general area over the scaphoid and the second slider acts as a bridge and stops the grab and twist effect.

This system protects the hand from compression fractures and hyper-extension, caused by the grab effect when a leather palm grips the road surface and forward momentum carries the rider’s body over the hand.

Knox Handroid’s with a set of SPS that has done its job during an off.

The basic principle is that SPS allows the outstretched hand to slide along at the same speed and remain in front of the rider’s body.


Knox SPS is becoming increasingly popular as riders and racers begin to understand and appreciate its real world benefits. SPS is fitted as standard throughout the Knox range of Hand Armour for motorcyclists and MTB riders and is widely used by other brands, including Weise, Racer, RS Taichi, Richa, Gimoto, Spyke, Polo, Teknic, Scorpion, Evolution, Lookwell, Damen, Drenaline, RedLine and many more.

Knox SPS Technology was also imitated by other brands on the market.

“If it doesn’t say Knox, it’s not Scaphoid Protection” says Knox Managing Director Geoff Travell.
