Purely on looks it feels like they've forced that idler in their existing frame a bit rather than designed around it . Strong team this year on Trek so the proof will be in the pudding 🙂
Yeah I agree, looks a bit bodged. But Trek do have plenty of experience with HSP systems as the original Session 10 had one.
Should've made it look like a Diesel. That'd look more bodged but much cooler.
The paintjob really draws attention to it.
I've never given treks a proper look over, have they always ben linkage single pivots?
looks like a pivot at/incorporating the axle.
Yup, think they call it ABP?
I think I can hear the distant cheers of their warranty department after they've given it a quick look and noticed a distinct lack of thru shaft on the shock. All eyes on the rest of the range to see if their prayers are answered...
Is it still a mule/test donkey? Production will surely be in swoopy sexy carbon and might look a little more finished.
It does look a little oddly proportioned but if its fast, thats all that matters.
Trek must be doing something right with it if they've managed to get vergier/vali/wilson to race on it this season.

Offered them a suitable pay deal...they are unlikely to be that picky about what they ride if the money is good...
(I've no idea if that is true - I'm in my armchair soapbox and just having a moan in prep for becoming a grumpy old man as after yesterday's bike ride, I reckon that can only be days away!!!)
I had a Session 7 back in the day and I think it was made out of dark matter.
“ have they always ben linkage single pivots?

From a pedalling, axle path and leverage curve perspective it’s a linkage driven single pivot but from a braking perspective it’s a true four bar.
My five year old had me doing some drawing with him at the weekend - he was drawing an exciting scene featuring a blue whale and a selection of dinosaurs, whilst I was trying to sketch out a high main pivot with concentric axle pivot suspension design like this, because I’m convinced it’s the best way to make a DH bike suspension system.
I’m glad to see that Trek were already on the case!
A normal linkage driven high single pivot is great apart from the brake squat being super high, so the suspension hugely stiffens up under braking. I’ve seen some attempts at a high main pivot four bar (is it a Horst link, really?) but they have a much less rearward axle path because the instant centre is so far forwards compared to a single pivot.
With this design you get the rearward axle path of a high single pivot but the braking behaviour of a high pivot four bar, so you can dial down the brake squat to that nice 80-90% range instead of being more like 150%+.
The other way to do it would be a floating brake mount on the Commencal etc designs - maybe we’ll see that but I suspect marketing may stop them trying it in the open...
I loved the old Session 10, I wonder how it would ride these days with a -2* headset, offset shock bushes, etc and modern suspension and parts? It had a very up to date 64* seat angle if IRC (LOL)
Rode a few, always wanted one, always too poor.
Looks like it’s had a big hit on landing, squashing the top tube/seat stay junction down.
