Lightweight Carbon Frameset With a focus on cutting-edge, technical, and stylish engineering solutions, the blend of three carbon composite materials has produced a fast and lightweight frameset. The revamped frame design shifts the rear brake underneath the bottom bracket. This new position has allowed De Rosa to boost braking power, give the frame clean lines and to remove the seat stay brake arch. This design enhances rider comfort but without sacrificing the performance.The integrated fork, steering tube, and frame axis are designed to improve overall aerodynamics. Wiggle Prepared and Quality Checked Rest assured that each frame is fully prepped by Wiggle's team of qualified bike mechanics to ensure it arrives in perfect condition.
