The YOELEO Altera G21 DB gravel frameset is widely praised for its robust T800 carbon construction, excellent tire clearance, and practical features like T47 bottom bracket, UDH compatibility, and internal storage. However, it is not the lightest option, with measured weights ranging from 1,170g to 1,400g depending on size and accessories, and some riders find the ride quality lacks engagement. Overall, it offers strong value and premium feel at a competitive price.

Reviews & Ratings
16:56The Yoeleo Altera G21 DB frame is praised for its high-quality paint job, excellent packaging, and thoughtful details like internal storage and a round seatpost. The reviewer notes it feels like a frame over twice its price, with a weight of 1.33 kg (without accessories) and a complete build weight of 8.78 kg. The frame offers ample tire clearance and is built for durability, though the weight is not groundbreaking. The reviewer plans to race on it in major gravel events.
22:49The 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.
23:02The 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.
21:12The 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.
21:40The reviewer provides a detailed analysis of the YOELEO Altera G21 gravel frame set for 2025. They highlight its revamped design, noting it as YOELEO's flagship gravel frame set with significant improvements over previous models. The reviewer is excited about building it up and praises its thoughtful features, quality, and attention to detail throughout the video.
20:33The reviewer discusses the Yolio G21 Altera gravel bike frameset extensively throughout the video. They highlight that this is the updated version of Yolio's gravel bike, featuring a silver champagne color and several key updates. The reviewer praises the frameset for its internal storage options on both the top tube and down tube, upgraded T47 threaded bottom bracket, UDH (Universal Derailleur Hanger) compatibility, and revised geometry to prevent toe overlap. They also mention the frameset's compatibility with up to 53C tires and its 27.2 round seat post. The reviewer notes the frameset's high-quality fit and finish, comparing it favorably to premium Western brands.
53:30The reviewer discusses the Yolio Altera G21 DB Gravel Bike Frameset extensively throughout the video, highlighting its features, build quality, and performance. They mention it as a redesigned, very capable gravel race endurance bike with a UDH hanger, T47 bottom bracket, and clearance for up to 700x53C or 650Bx2.1 tires. The frame has multiple mounting points for bottles and storage, a nice paint job, and comes with an integrated handlebar system. The reviewer also notes the frame's weight, warranty options, and compatibility with various components.

The reviewer finds the Yoeleo G21 DB Pro gravel bike to be a capable and easy-to-ride machine with a decent weight, relaxed geometry, and ample tyre clearance, but criticizes it for lacking rider engagement and feedback, resulting in a 'dead' feel that reduces confidence in corners and descents. It is described as 'middle of the road' and best suited to riders who view the bike merely as a tool rather than seeking a strong rider-bike connection.

The reviewer states that the YOELEO G21 Altera is an improved version of the previous G21 frameset, highlighting several new features and sharing their positive experience building and riding it.
