Features: - High precision CERAMIC bearings with maximum precision and low friction that increase durability. - Progress cassette body option Shimano MICROSPLINE compatible made of CNC aluminum. Reinforced with 2 oversize bearings to resist high loads. - Rear hub with a very strong three pawl ratchet mechanism. Engagement with 3 oversize pawls and steel ratchet with 30 teeth’s. - A hub with Parallel Drilling technology ensures high precision 100% aligned bearing seats. Progress hubs and bearings are designed for light weight, long lasting and best running performance. - RS-1 Predictive Steering - Front wheel or hub compatible with RockShox RS-1™ Fork 110mm - LEFTY - Front wheel or hub compatible with LEFTY 2.0 and SL - Cannondale™ Fork - Crashed wheels! In case of bad luck, Progress supports you by offering replacement rims for half the regular price during 1 year after purchase. - SAPIM CX aero spoke is the choice of champions and many teams at the Pro-Tour. Made in Belgium with an aerodynamic advantage and unbelievably high fatigue test results. We build them into our lighter wheels to achieve durable and long lasting wheels which don’t need to be re-trued. Each Progress Wheel, hub and rim is designed with perfect spoke angle to release extra stress. - New Oversize hub body CNC made of AL7075 super lightweight. 3 cross straight pull for a 20% stiffer wheel and better aerodynamic performance. Super precis Japanese cartridge bearings with very low friction and bigger size for long lasting. 15mm CNC made Aluminium rear axle and free hub. Classical engagement with 3 oversize pawls and steel ratchet. New SRAM XD free hub with 3 bearings and Shimano with 2 bigger bearings, free hub Shimano and SRAM interchangeable without any modifications or adjustment. Road Nitro rear with 2:1 spoke lacing. - Boost hub 15x110mm front and 12x148mm rear. This technology has an enhanced flange distance. It has many significant advantages: flatter spoke angle and improved symmetry allow building a stiffer and stronger wheel. - Progress cassette body option SRAM XD compatible made of CNC aluminum. Reinforced with 3 bearings to resist high loads. - TLR Tubeless Ready We’re using most common rim bed design. Its advantage are excellent rolling resistance, fewer punctures and easy mounting tire. - As much as possible weight reduced. Not recommendable for riders whose weight is over 90 Kg. Lightweight wheels provide much better acceleration and climb.

Technology: Pal-Tech: - High precision aligned bearing seats with parallel drilling technology made by high-tech CNC 5-axis machine. - 100% parallel to the axis of the spindle. - 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. 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. Tire Width Recommendation: - For maximum aerodynamic efficiency on your wheels we recommend that the width of the tire does not exceed the outer width of the rim. Our AIR + PLUS rims are very wide with 27 to 30mm, opening the tire enough so that the tire and rim walls form a seamless line.
