SPINE TIRE INSERT

All you need is a SPINE !!!

The SPINE tire insert is designed to protect your rim and tire from impact and pinch flats.

The high-quality and density of the polymer provides the perfect balance between durability and weight. 

 

The insert is 45mm wide and suitable for rims from 30mm to 43mm and  for 26", 27.5", 29" rim sizes. 

 

The unique SPINE like design allows the insert to compress during the installtion and fit easily. 

The air flow through the slots allows the tire to compress and rebound in a more natural way without losing control and traction.

 

The SPINE insert has been tested for hundreds of hours in all conditions, the resoult was amazing! zero dents and no flat tire during the test.

DO NOT RIDE SPINELESS !!!
