The CushCore Pro Tire Inserts Set allows you to push your mountain bike tyres to the limit. The CushCore Pro insert is specially designed for rocky surfaces where good and controlled damping is very important. The CushCore Pro insert provides more stability and damping while riding, so you'll be faster and more confident on crosscountry trails. Extra protection and improved handling If you often ride hard and aggressively over rocky terrain, the CushCore Pro will protect your rim from damage thanks to the improved damping. The CushCore Pro also increases stability and cornering speed by preventing the tyre from rolling sideways. Same for the straight stretches on rocky terrain, you'll notice that the CushCore Pro improves handling as the tyre is less jumpy and will therefore feel more stable. Additionally, the rolling resistance is reduced by the CushCore Pro inserts, so your forward momentum will last longer and you can continue to perform at full speed. Moreover,with CushCore it is possible to ride with a lower tyre pressure, without experiencing most of the adverse effects associated with low pressure tyres. Including valves The set also comes with sleek and green coloured CushCore valves. These are specially designed for use with all CushCore inserts. The air comes out at the side instead of the top, as with normal valves. As otherwise they would be blocked by the CushCore inserts.
