Designed for everyday

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.
