Race designed, everyday training.

Cross is hard on the budget, but it’s true that better equipment makes for better racing. Like all Rolf Prima wheels, the ECX Disc wheelset is built by hand in Eugene, Oregon to give riders a high quality build at a more modest price point. Available in either a tubular or clincher configuration, the rim profile offers precision cornering, descending and overall ride comfort.
