Hmm, interesting that it showed up on the “New Products” page and not on the main page, but anyway, as mentioned above, it’s there, and available if you want to buy it from Serpent CN direct:

I like the fact that they went with the wide stirrups front and rear - those tiny ball bearings held by only c-clips were a liability. The “flex-bridge” system they added looks interesting, as is the updated servo mount/receiver plate, although I have to admit that I still miss the weight management options the ‘21 had, even if some holes are effectively useless in the rear if you have an ESC for Mod racing.

Looks like this will be an easy upgrade for a ‘23, despite the sting of buying a new chassis.
