Knox Scaphoid Protection System | Explained

Knox Motorcycle Gloves

British impact protection specialist, Knox, has developed a dual compound version of its patented, the Scaphoid Protection System (SPS).

Constructed from a combination of LDPE (Low-density Polyethylene) and TPR (Thermo Plastic Rubber), the new version offers more flexibility, extra cushioning and comfort and provides superior sliding ability, increasing protection of the vulnerable scaphoid bone.

Experienced motorcycle racer Ian Lougher, who not only has 10 Isle of Man TT victories to his name but also won the NW200 nine times, is one of many riders to experience the positive benefits of Knox SPS first hand (pardon the pun):

Ian Lougher says: “The Handroid gloves are something else, fantastic to wear, and with their specially built in plastic skid patch on the palms helping to lessen the risk of a broken scaphoid. If you’re unfortunate enough to suffer a highside from the motorcycle, they really do work.

“I must admit I was very sceptical initially when I was first told about this, but when it happened to me at the Ulster GP, where I came down from a great height landing on my hands, I am sure the gloves saved my wrist after such a huge highside.”

A fractured scaphoid is one of the most common wrist injuries and is usually caused by a fall onto an outstretched hand. Motorcyclists are particularly vulnerable to scaphoid fractures, due to the “grab” effect: the gloved-hand contacting the road surface and dramatically slowing, allowing either compression or hyperextension of the wrist. Painful and notoriously difficult to heal, a broken scaphoid can put a rider out of action for weeks.

The patent protected Knox Scaphoid Protection System consists of two low-friction pads positioned on the palm of each glove, developed to eliminate the ‘grab’ effect of traditional leather-palmed gloves. The SPS allows the hand to slide forward at the same speed as the wearer, reducing the risk of breaks and fractures.

Knox’s innovative new Dual Compound SPS uses both LDPE (Low density Polyethylene) and TPR (Thermo Plastic Rubber) to increase protection and comfort considerably. The new dual compound structure has several benefits, with an increased ability to slide – LDPE has a self-lubricating property which helps reduce friction and it’s also resistant to heat and is able to maintain structure up to 95 degrees Celcius – giving constant protection even during long, high-speed slides. The TPR section offers more cushioning and the softer edges means they are more flexible and less stressful on supporting seams and materials.

The new Knox Dual Compound Scaphoid Protection System is now available for OE fitment. Knox’s range-topping Handroid glove is expected to be the first in the market to feature it.
