ULTRON 85 + ULTRON DISC
the ultimate race setup for athletes focused on pure speed.
The ULTRON 85 front wheel combines a deep aerodynamic profile with predictable handling, helping maintain speed while remaining stable in changing wind conditions. At the rear, the ULTRON Disc minimizes aerodynamic losses and delivers maximum efficiency where airflow around the bike is most complex.
Together, they create a complete aerodynamic system designed for long-distance racing, high-speed courses and athletes who want to turn every watt into forward motion.

RON Wheels
I’ve used them for 2–3 days, including one day of competition. The feeling is very good. They seem very fast to me and really help at high speeds. On the competition day, they performed very well.
