Switching to the Norwegian-designed Unaas X50 full carbon spoke wheelset, CT Yeh embarks on a high-spec wheelset performance showdown. The video begins with a detailed structural and craftsmanship review by professional technicians at 501 Bike Shop, followed by an invitation to the elite climber "Wei Wei," who has achieved a sub-two-hour Wuling (Hehuan Mountain) time, for a rigorous dual-sided power meter comparison on a climbing route. Beyond testing the stiffness and pedaling response of deep-section carbon wheels on steep gradients, the session continues with multiple extreme sprint intervals and high-speed inertia tests on flat roads. Can carbon spokes break the stereotype of heavy aero wheels on climbs? The high-tension real-world testing is full of highlights.
