No offence taken here.
One other thing to note is that what you'll most likely smash on a rock is the link which is alloy. Not to say it's impervious to damage, but something to consider.
Transition Spire, in carbon, 35lbs with Boxxxer, and full fat CushCore, you’ll love it!
Swap to a Cascade link, and you’re running 180mm travel rear, with a slightly adjusted kinematic that is more sensitive off the top.
I’m game for a 73mm crank, i’ll change to that. But not happy with changing the wheelset as well - need it at 12x150 or 12x157 for the rear wheel (really happy with current wheels, plus a new wheelset means more money spent - the wifey’s gonna shoot me 😁 ). There’s 1 new model that covers everything there is to be covered, but they aren’t releasing it yet, not sure if it was covered here in this thread - the Trinity MTB. Current prototype is the V2, the V3 is supposed to be the series frame. But no release date yet!
So what is below the BB? Is it the linkage? I can't imagine it's the shock...
What we've seen from all the shots makes this quite plausible.
Could be something else entirely though.
Seems like (For the time being) 12x148 is the go to standard.
Depending on the hub you’re running, there are adapters to make things work. Or a quick visit to a machine shop for some spacers.
i feel like they are trying to make the bike Have a similar idea to the Stumpjumper EVO - where the wheel moves rearward for the first 30% of the travel but then suddenly moves forward... This would allow it to be "unloaded" and move rearward initially to help the wheel get out of the way but then move forward on the backside of the "hit" so it pumps really well. with little anti squat deep in the travel Itll give it a HP feel and not blow the feet off.
the way the bike rode in the video thats exactly what ive taken away from it.
Im no bike engineer by any stretch - i just study bikes like a NERD lol
the current demo uses a fixed lower arm while the shock it pushed by the upper linkage and in return requires a long FSR upper link to get full travel - this is why we have been seeing alot of linkage prototyping, they are changing the leverage etc.
However due to the long ass upper link and very long chainstay link which from what im roughing drawing out is a smooth transition from sag to 100% - which is obviously similar to the Enduro as that thing just plows aswell.
The evos wheel curve goes back then abruptly goes forward and its why the bike feels like it can plow but be super fast as it can be efficiently pumped - this comes from the short(er) upper link found on the EVO and the prototype demo.
this cant be simply applied to the current demo as would require a new rear design since that FSR link places a big role in leverage and overal travel control.
Im guessing the prototype is a "expanding rotating linkage" lower linkage that will be similar to the range but using the FSR short link up top to suddenly "pull the rear wheel forward" which in combination with low anti squat should remove the need for a idler, especially if using the ochain or WRP chainring setup.
The range uses a fixed upper arm design so it just feels dead the whole time while making the chainstay go super long and causes a heap of kick back meaning it needs an idler
however, in the end... if you want a DH bike to go fast without all the BS, get the session - I wont get into detail on it but its got some black magic going on by moving the top linkage forward and higher.(similar to the new slash) note the short rocker pivot compared to the old one
Stump Evo -2.5mm
Demo -4.5mm
I would hope the new demo gets closer to the -6 or 7mm and run an Ochain to combat the pedal kick.
As to the Session 'black magic', the only results of moving the upper link forward and up are decreased anti-rise and a more progressive leverage curve (in this particular configuration). Not sure what else you could be referring to, unless it's something like frame stiffness.
Forward axle path does not necessarily mean negative pedal kickback.
So due to the bb drop below the axle, the chain continues to grow even though the axle path is moving forward in the second half of the travel. So the wheelbase is always growing, similar to a HP bike, but just not at the same rate?
I find we get caught up in the numbers so much we forget to take a step back to recognize we are talking mm’s here, and just how small those actual differences are….
Shit, I’m gonna need to draw this to get it right in my head.
Front and rear travels doing different things throws a wrench into everything (keep the front extended, squat the rear and the wheelbase just might extend quite a bit actually).
And yes, millimeters, actually quite small
