The All Carbon Series is a very cost-effective pair of wheels. It uses T800 full carbon rims, hard ceramic bearings, and two freehubs to choose from: Shimano and XDR. Whether in speed or stability, ideal for riders using rim brakes. High Performance Wheelset The rim utilizes the second generation of automated plastic winding technology and also references enhanced toughened epoxy resin material to strengthen the rim's impact resistance, increasing the rim's impact resistance by 16%. Superteam Large Flange Center Lock Hubs In order to improve the tension of the spokes on the non-driven side of the wheelset, as well as to improve the stability of the wheelset, Superteam has adopted a large flange design on the driven side of the CX22 carbon spoke wheelset, which is better suited to the angle of the spokes, and can effectively increase the driving force arm to improve the driving efficiency of the wheelset. Integral Rim Brake Surface Design The rim features a one-piece hollow rim design with an integrated braking surface for enhanced structure and performance. You don't have to worry about the braking surface peeling. The K-line brake edge dissipates heat and drains water, eliminating the risk of brake lock and reducing the braking surface temperature. Freehub Body The S-All Carbon series has two different freehub bodies: 1. The Shimano freehub body is made of high-quality materials and has good durability. It also uses high-quality bearings and engineering design to provide riders with a smooth ride. 2. SRAM XDR is a special freewheel body standard designed for road and mountain bikes. Its design allows for larger diameter bearings, so it can provide higher rigidity and stability, this means that the XDR freewheel body can provide better transmission efficiency and reliability in high-speed riding and high-torque situations.
