As far as I can remember every coil shock except DHX2 has a 1/2" shaft or bigger, EXT is 14mm and Push has a specific shaft for yoke mounts and E-Bikes.It seems like all versions of coil shocks that came with the "Sidearm"/2nd-gen Kenevo (that is, the RockShox Super Deluxe Coil Select and the Marzocchi Bomber CR) from Specialized have been equipped with 1/2" shafts.
First ride review: 2020 Specialized Turbo Kenevo Expert – more capable than ever, but is it more fun? | E-MOUNTAINBIKE MagazineThe new Specialized Turbo Kenevo is all about having fun on the descents. It's got a new frame, new motor, much more robust spec, which promises to be even better for those big hits and demanding descents – but will everyone benefit? We found out!ebike-mtb.com
Perhaps the potential shock side-loading of a given suspension system and the side-loading tolerance of a given shock are things the industry/MTB-media need to do a better job educating lay consumers (and the lay masquerading as shop wrenches) about... and make the requirements/abilities more obvious. For example, I was also trying to find the shaft diameter of the Öhlins TTX22M that was equipped on the first-gen Kenevo and some "Sidearm"/2nd-gen Stumpys... but to no avail. It's strange that something as simple as this dimensional spec is not made more readily available. (Not to say shaft diameter is necessarily a be-all-end-all indicator of side-loading tolerance... but at least suggestive.)
Even in the absence of industry cooperation (I mean, nobody wants to admit that their suspension design requires a heavier-duty shock construction), more education about this issue from the MTB media might help lay consumers (and again, the lay masquerading as shop wrenches) think twice before throwing a thin-shafted shock onto a suspension design that has apparently always come from the factory equipped with burlier shafts.
I mean, you can install a Rock Shox SID fork onto a Kenevo... but I don't think anybody would think that to be a good idea nor expect the resulting machine to live up to the duty level the Kenevo ad-copy suggests. And that's because we consumers have been well-educated about stanchion diameter as a proxy for a fork's duty level.
