A May 2026 first look at a borrowed size S X-LAB RT9 complete bike with Dura-Ace Di2 and Branta carbon-spoked wheels, covering a weigh-in, a wheel swap, sizing, the component-swap policy and an early frame-finish problem. It is an international complete build, not the mainland China frameset package recorded here.
CADE Media · 2026-05-06. CADE Media borrowed the size S bike and says it was not paid, did not keep the bike and X-LAB had no control over the video. The description names Garmin as a channel sponsor.披露依据.
要点
实测0:59The borrowed size S complete bike, with Dura-Ace Di2, in-house Branta 50 mm carbon-spoked wheels and 28 mm Michelin tyres, weighed 6.39 kg as shown; the presenter thought that a little above X-LAB's claim.
发布时价格2:18At publication X-LAB sold it as one complete build at US$9,150, well below a top-spec Specialized Aethos or Scott Addict RC, and said framesets would follow with prices unconfirmed.
骑行感受3:08On rough roads and patches of gravel the presenter found it the harshest bike he had ridden. Letting air out from 60 psi did not help, and he blamed the Branta C50 ULR carbon-spoked wheels (hooked, 50 mm deep, 22 mm internal).
骑行感受5:22With alloy DT Swiss wheels and tubed GP5000 tyres the same frame rode much more smoothly and handled well; he would replace the stock wheels, and a second rider also found the Branta wheels very uncomfortable.
适配检查6:33Only four sizes, XS to L. The XS suits smaller riders, but the largest is about the size of a 56 cm Specialized Aethos; X-LAB said XL or XXL tooling depends on demand.
售后支持7:16Stock cranks are short and bars narrow. X-LAB said RT9 and AD9 buyers can swap cockpit and crank sizes free of charge after ordering the stock bike.
做工与问题10:00The first-batch frame finish marked from a tap with a pump and even a fingernail. X-LAB first called it the intended finish, then said newer frames use a more durable regular clear coat; the hosts expect that to affect the frame weight.
