Altera G21 DB

The 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. They highlight the excellent packaging and included accessories, versatile build options, and competitive pricing.

The reviewer states the full name for the frameset is the 'Ulio G21 Alterara gravel frame set' and later refers to it as the 'Altera' and 'Alterara'. They describe it as UCI approved, robust and strong, though not the lightest frame available. Key features highlighted include the T47 threaded bottom bracket, UDH compatibility, two storage compartments, mudguard/fender mounts, and clearance for up to 53mm tires. The reviewer compares it to the older Yolio G21 model, noting differences like the round seatpost, updated bottom bracket standard, and added storage. They praise the quality of the threads, prep work, and included manual, concluding it is a good option for a durable, bombproof gravel bike for off-road enjoyment rather than serious racing.

The reviewer discusses the YOELEO Altera G21 DB Gravel Bike Frameset extensively, comparing it to its previous generation and highlighting improvements and remaining issues. They note that the new version addresses several quirks from the first generation, such as the short front end and steep head angle, which caused toe overlap. The reviewer praises the updated geometry, which now features a longer front center and slacker head angle, eliminating toe overlap even with larger tires. They also highlight the improved seat post system, now a twin-bolt design, and the inclusion of a UDH hanger with a spare provided. The reviewer mentions the robust construction and wall thickness, though notes it is not lightweight. They also discuss the frame storage bags, which are well-executed but too small for practical use. The reviewer appreciates the documentation and part list provided by YOELEO, calling it exemplary. However, they point out some remaining issues like the fork expander system and front brake alignment.
