Chinese BikesSource-based editorial review; no hands-on testing.
A convincing aero-gravel shell with 53 mm rear clearance, but its gravel-race geometry and flagship price keep it from being a literal aero-road answer or a value choice.
Best for: premium gravel racer, wide-clearance race buyer

The owner found disappointing paint-finish defects right out of the box, especially around the brake mounts, threaded inserts and down-tube storage hatch, and opened a claim with the seller and Winspace.
Calls it a phenomenal value aero gravel bike for about US$5,200–5,400: 58 mm front and 53 mm rear clearance, internal storage, UDH, T47 and a road-capable look. One niggle: the supplied caliper spacing was set for 140 mm while a 160 mm rotor was fitted, with no note explaining it.
ConfigurationSize L complete bike with SRAM Rival XPLR 1×13, Gryper 2 D45 wheels and 40 mm Michelin Power tires; 8.88 kg with pedals and the included frame bag.
