Why spend a fortune on a disc wheel when a cover does the job just as well? This product is a game-changer—delivering noticeable watt savings, extra speed, and improved stability in high winds and crosswinds. I’ve used it in top races like Ironman Wales, Ironman Nice 70.3, Ironman Swansea 70.3, T100 London, and Challenge Wales. It performs exceptionally on both hilly and flat courses without adding any noticeable weight. Highly recommended for anyone looking to boost performance without breaking the bank!
