The most versatile size in the Diamana line up, offering increased protection and tyre support. The new standard for Trail/enduro/Down country inserts. Using lateral channels to create a Ventri effect, meaning that air flows through the channels which increase speed and helps with rolling resistance. This design along with the new dimpled effect on the inserts helps to massively reduce tyre rebound and leaves the tyre at constant pressure on the ground during any impact. Tested by some of the best riders in the world in some of the toughest conditions, they offer performance at an amazing low weight of only 145g per insert.
