Progress Space Tubular Road Rear Wheel

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.Features:- Hand built: Extremely durable hand built wheel. High durability and high precision.- 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.- C.S.T Carbon stabilizer.The incredibly strong Cyanacrylat composite center is the backbone of our brake walls.Makes our clincher rims 90% stronger than regular carbon rims.- E.C.S Extra Carbon Strip. Provide extra stiffness on spoke holes. Ensure the rims will not be damaged if a spoke breaks and allows a better spoke tension. Our rims are capable of withstanding a spoke force of 300kg.- Ultralight: As much as possible weight reduced. Not recommendable for riders whose weight is over 90 Kg. Lightweight wheels provide much better acceleration and climb.- Freewheel: PROGRESS cassettes bodies can be easily removed and replaced with no extra adjustments. Switch quickly between Shimano, Campagnolo, or SRAM cassettes.- Nitro: 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.- 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.- Diamond: DPL Brake Surface, Diamond Polishing Treatment. We are using advanced machinery & Diamond Polishing Treatment (DPL) for brake surface, allows the brake pad to work directly on 3K woven carbon fibers. This new process eliminates ´´run-in´´ periods, improves braking performance in wet and dry weather conditions, and creates much better braking performance.TLR Tubeless Ready We're using most common rim bed
