Riding a bike over uneven terrain means that it is impossible to hold the wheel straight. It bounces, moves, you correct your direction to pick the best line, but you do not want to slow down. This means that your front wheel will not spend much time facing the direction that you intend to travel. The Venn Var 40 TCD carbon rim was developed to make you go faster in real gravel conditions, not in a tunnel. The rim’s spoke hole strength is 100% higher compared to other carbon rims in the market. This ensures that you can use your wheels in any condition without fear of damage.
