Disc brakes are recommended for virtually all riders. The weight penalty is now under 200g, and the benefits — consistent stopping power in all conditions, better modulation on long descents, wider tire clearance — far outweigh the small weight increase. Rim brakes make sense only for riders building the absolute lightest possible bike for hill climb events where braking is minimal, or for riders with existing rim brake wheelsets they want to keep.
