Created: July 18, 2025The reviewer provides a detailed analysis of the Yolio Alterara G21 gravel bike frameset, which is the third generation of their gravel frame. They discuss the updates from previous versions, including the addition of in-frame storage, a switch to a 27.2mm round seatpost for more compliance, full UDH compatibility, T47 bottom bracket with inboard bearings, and tweaked geometry to address toe overlap in larger sizes. The frame is made from T800 carbon, which the reviewer notes is durable though not the lightest, and is available in seven sizes.
