YOELEO has launched a brand new technology of their G21 gravel body known as Altera. In comparison with the earlier technology, which I had the chance to check and nonetheless personal, it presents a number of enhancements.
The G21 Altera now has two hidden storage compartments to stash instruments or extra gels. In fact, it’s also possible to use extra bottle cage mounts for those who choose bike packing or endurance biking.
Regardless of the compartments, the body is barely lighter. I estimate 50g decrease weight in the identical body dimension. Along with the brand new YOELEO NxT SL2 gravel wheels, it can save you over 200g on the entire bike.
One other distinction is within the geometry division. Altera has a slacker headtube angle, an extended wheelbase, and a shorter stem. This could result in higher stability and management on tough terrain, and you must keep away from the toe overlap.



YOELEO additionally jumped on the UDH (common derailleur hanger) wagon, which is much less liable to bending than a regular derailleur hanger on affect.
When it comes to driving traits, the G21 Altera must be extra snug due to the brand new seatpost, which offers higher flex and, due to this fact, absorption of driving vibrations. The seatpost is spherical with a 27.2mm profile, so if the unique one doesn’t fit your needs, you possibly can simply exchange it, in contrast to the earlier technology’s D-shaped seatpost.
The underside bracket is manufactured from bonded aluminum and molded into the body. This could guarantee “good alignment, improved sturdiness, and a lighter general construct.” Nicely, we’ll see.
The next desk summarises the principle technical specs.

Sadly, the value elevated a bit. It jumped from $1136 to $1420. Is that this value bump justified? What do you suppose? Let me know within the feedback and keep in mind to hitch my Fb group the place we talk about all the things about Chinese language carbon.
