DID I BUILD ULTIMATE GRAVEL BIKE?!

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.
