Look at the forces that are coming from the rear wheel through the yoke and into the shock - there's not much structural support there for side loaded inputs. If everything is well aligned and the shock's approved it should be fine, but coil shocks are often not approved due to the thinner shaft.

So is this a yoke or a better design for side loading?

DVO and EXT coils are often ok in this case but i am still iffy about it. The new 2026 Fox coils have gone to a 12.7mm shaft so we'll see... quite a big jump from their old 9mm and 9.5mm ones.

I'm no engineer, but the shorter the yoke the better I would imagine.

My highlander runs a yoke of sorts which Formula didn't approve for their first gen Mod coil, but they now have a yoke approved one. Didn't even occur to me that it had a yoke because of the way it's hidden away:

Ultimately the bulk of the millions of riders on Specialized yoke bikes aren't destroying their shocks on their green flow trails.

Pretty sure for the most part it's not going to blow anything up immediately, but I guess a shock may wear out more quickly. Sending it with a non-approved combination may have different results.

Maybe it’s a grift for the Specialized service departments.
 
Not to be condescending @Jabubu but also consider that your riding style may or may not be generating a lot of ooooomph2. These sort of lateral forces are a more common issue high speed railing berms on gravity trails, landing your jumps off centre or still whipped out, ploughing rock gardens, plunging drops, and of course my specially...casing jumps. Throw in a bit of expecting an all mountain or trail bike to handle being ridden like an endruo or down hill bike as well and you start to see where these issues might be more prevalent.

That's fair :)

I'm more up and down than lateral.

Unless you're referring to my midriff!

It is my understanding from your posts that your riding style fits in with the all mountain or trail riding genre rather than entering the send zone?

That is correct, i don't really send it but I do the odd drop or Roost :)

That's better, as the little linkage keeps the chain stay controlled and wouldn't have much rotational force into the shock shaft. Longer free yoke are inherently unstable and then only made worse by rotational forces if the bearings are not perfect.

Ah...because if you were achieving roost in the sense that I know it, you must be driving an inhuman amount of thrust through those cranks! If you are, hit me up for some cranks that can survive your torque levels.
 
@Jabubu - I rbroke the shock bolt in my 2003 specialised enduro. The shock went down through the linkage and snapped the linkage. That shock was never serviced.
On the 2014/2015 enduro I stuffed 2 dbInline shocks, upgraded to the DBAir and had to get the shock rebuilt after every trip to the alpine regions. It used to eat seals. Actually reminding me of all of this has helped to me be ok with retiring the frame.
