The reviewer purchased a BXT gravel bike frame for approximately £300 after searching for the cheapest options. They unbox and examine the frame, noting it arrived in 4-5 weeks. The packaging was basic but protective. The frame is a matte-painted carbon model called the 'Gravel 135' with a UDH rear derailleur hanger, includes a seat post, handlebars, fork, and all necessary accessories like a thru-axle, bearings, and seat clamp. They are generally impressed with the initial quality for the price, noting the carbon weave is visible, the frame feels solid, and it has 50mm tire clearance. However, they note minor issues like paint overspray, a questionable headset bearing measurement printed on the frame, and a potentially loose bearing fit. They plan to build it with parts from their current bike to test ride it.
