PSG (Perfect Spoke geometry): - Every Progress Wheel is designed for his specific operation purpose. Our choice of rim, hubs, spokes and lacing pattern isn’t just a coincidence. - We strengthen rims at every spoke hole on each rim we develop. The spoke hole and nipple seat is perfectly aligned with hub and spoke angle. - This creates a perfect spoke geometry which allows us to use high spoke tension by an evenly and equal tension distribution. Releasing excessive stress from spokes we get long-lasting and high performance on every wheel. ORTF (Optimized Rim & Tire fit): - Progress offers a wide range of wheels which are perfectly designed for each riding style. Every rim shape we offer matches with the need of modern tires and their installation.If you follow our rim dimensions you’ll find extra wide tire fit. Wider tires roll better, improve handling and cornering. The appearance is a perfectly integrated tire and more homogeny. Please follow our Tire Width Recommendation.
