Is a carbon fiber racing helmet worth the extra cost?

For serious racers who train frequently, carbon fiber is worth the investment. The weight savings of 50-100g compared to composite shells reduces neck fatigue during long training days and can improve head position at speed. For racers who only compete occasionally, a composite-shell FIS-certified helmet provides the same safety certification at a lower price. The protection level is equivalent — carbon fiber's advantage is weight, not impact absorption.
