The Matter one20five wheel is made for 3 x 125mm setups. This setup is fast, very fast, but also gives you more footprint to the asphalt for better push and grip. It is lighter and requires less bearings which again results in less friction and weight. Add to that the well known and technically superior Matter Urethane for maximum rebound and speed. A 3 wheel setup also enhances control due to the centre of gravity being put on the middle wheel, making it easy to apply your favourite push technique.
All this makes them ideal for highspeed and endurance skating with thousands of strokes.
