PROGRESS Space Disc LTD road wheel set Black / Copper, 12 x 100 / 12 x 142 mm

AIR Wind tunnel test 7,4 Watt air resistance by 45Km/h High speed technology which was developed for time trail and Ironman now the SPACE is successfully worldwide race proven and tagged with gold medals and many podiums. GRAPHENE is the world’s strongest and lightest material which offers a totally revolutionary rim technology. New Optimized rim design Air+Plus with improved aerodynamic efficiency. Lateral wind is no longer a problem anymore thanks to the new Air Plus U‐Shape rim design with 28mm external width. This allows the use of wider tires without negatively influence on the wind flow. Lightweight construction for hard race courses. Featuers: - These wheels are one of the fastest with best aerodynamic performance you can find. Check AIRBUS Wind Tunnel test in progress technology. - GRAPHENE is the world’s strongest and lightest material which offers a totally revolutionary rim technology. Graphene-enhanced full carbon rims are 50g lighter and 20% stiffer. - Rear hub with a very strong three pawl ratchet mechanism. Engagement with 3 oversize pawls and steel ratchet with 24 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. - High precision CERAMIC bearings with maximum precision and low friction that increase durability. - 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. - AIR+PLUS High speed technology with optimized aerodynamic efficiency and less drag. Lateral wind is no longer a problem anymore thanks to the new 28mm wide U-shaped carbon rim. This design allows the use of wider tires without negatively influence on the wind flow, more tire volume, lower rolling resistance and better handling in crosswinds condition. The AIR+PLUS is successfully worldwide race proven and wind tunnel tested. (Check AIRBUS GST results) - Rod Hub’s with 12mm thru axles. - Crashed wheels! In case of bad luck, PROGRESS supports you by offering replacement rims for half the regular price during 1 year after purchase. - PROGRESS cassettes bodies can be easily removed and replaced with no extra adjustments. Switch quickly between Shimano, Campagnolo, or SRAM cassettes. - TLR Tubeless Ready We’re using most common rim bed design. Its advantage are excellent rolling resistance, fewer punctures and easy mounting tire. - 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. - Extremely durable hand built wheel. High durability and high precision. Specifications: Rims: - Graphene multilayer carbon fiber. - Super lightweight disc brake design. - Carbon UD and 3K spoke holes. - Air+Plus High Speed Technology. - Under clear coat transfer graphics. - ERD: 469mm - Profile: Profile: 80mm - External width: 28mm - Hubs: Nitro Road Disc Ceramic Center Lock Spokes: - SAPIM Aero CX‐RAY 20 Straight pull. - Hand Built with alloy nipples and secure lock. - Quick release/axles: 12x100 / 12x142 - Weight: Set Clincher: 1.810 gr - Set Tubular: 1.550g Limits: - Recomended rider weight limit: 110 kgs - Recomended tyre sizes: 23mm to 28mm Options: - Shimano HG cassette body compatible - Campagnolo cassette body 10/11S compatible - Sram XDR cassette body 10/11S compatible Technologies: AIR+PLUS High speed technology: Why is aerodynamic so important to your wheels: - When you race 40km/h your wheels are spinning double 80km/h, hard cross winds are capable to throw you from the road. - With our wheels lateral wind is no longer a problem anymore thanks to the extra wide and latest U-shaped design. - This design allows the use of wider tires without negatively influence on the wind flow, more tire volume, lower rolling resistance and better handling in crosswinds condition. 23 to 28mm tires are seating totally integrated into the rim shape and do not offer extra friction. - This shape has high aerodynamic efficiency in accordance to latest scientific findings from wind tunnel testing’s. - Comparing to regular V-Shape rims we reduced drag and crosswind drag coefficient by more than 30%. 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. 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. - Clincher or tubular tires from 23mm up to 28mm are perfectly integrated into our AIR + PLUS rims. - As a reference we have tested the air resistance of the APRIME in the wind tunnel with a speed of 45km/h with different tires.
