The downhill carbon rim is heavier weight due to the additional reinforcement. The thicker 4.5mm walls can handle heavier and more aggressive riders making this the best choice for freeride and downhill style riding. The increased volume allows you to reduce your tire pressure and get traction you've never had before.
