PROGRESS Sonic Road Rim

Progress now offer the latest revolution - a wide U-shape rim design using ultra-strong lightweight DYNAMAL aluminium. The SONIC DISC exceeds the aero performance and weight of many carbon wheels on the market giving you the flexibility of choice! 21mm tyre bed is the perfect size for modern tires from 25 to 32mm enhances aerodynamic, grip and increases rider comfort. On these wheels you can also find our NITRO Ceramic Disc Center Lock Hubs straight pull with high precision low friction NITRO CERAMIC bearings which we’ve been testing over the last 2 years with excellent results and riders feedback.

Less friction more speed and longer bearing life. 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.
