Reviews & Ratings
The BXT-SL-115 is a lightweight carbon fiber road bike frame purchased primarily through AliExpress/BXT Official Store. Users report frame weights around 962g (size 52cm) with derailleur hangers, and complete builds weighing 8.08-8.8kg. The frame features chameleon paint that changes color based on lighting, integrated handlebars, and a T47 bottom bracket. It accommodates various groupsets (Tiagra, 105, Ultegra) but requires careful component compatibility. Delivery typically takes 18+ days with additional shipping fees. The ride is described as stiff and responsive, though steering can be twitchy with a slammed stem. Tire clearance is limited to approximately 32mm.
