Love the look of that front triangle!
First time I've seen reference to the I-track patent on a Norco. Also, I wonder when these wheels are coming out?
Anybody know the release date of the new dreadnought?
They said be on the lookout for it in an email sent out today. Would assume this week or next... gotta compete with those new Norco high pivots!
Stoked for Hugh, back in early 2000's and I was in a mIRC Aussie mtb group chat and he was coming up with suspension ideas back then, we were all thinking he was a lunatic but here we are. Dude is switched on as hell.
How do I get on this email chain? Haha
15mm axle on that Push inverted fork
Astounding
It's probably been stated and I missed it but their is a countdown clock on Push's fork page. Nine One - PUSH Industries
Looks like tomorrow is the day.
stoked on the podcast/video we'll have tomorrow w/ darren. should explain any/all questions. (edit...yeah right...this is tech rumors, you'll have 4,000,000 other questions/observations no matter what : )
Just as an aside, congrats to Hugh McLeay (the i-Track guy) now that a brand as big as Norco is licensing his tech on two of their most popular models (Devinci and Trek can skirt around it, as the idler is still mounted to the swingarm).
Instinct tells me next week will be a busy one for new releases.
Do we know when the era wheel are going to be released
Product page currently 404s: https://www.pushindustries.com/products/nine-point-one
I don't have any idea when it's going to be released, but a friend was at a shop who sells them and has seen it (pics, geo charts, etc). He said he's pissed he sold his v1 as v2 looks like it's quite a bit different. Said sizing is weird (med is shorter than v1 and large is longer?). Said they've switched to a four bar design to be a pedal better, but possibly at the cost of dh performance.
I don't know anything about anything, but he seemed pretty bummed about it. I guess we'll see?
Can anyone give me a little TLDR about this iTrack patent thing? What it does and why its a big deal?
I'm not an expert, but as I understand it iTrack is the idler position at the pivot rather than on the swingarm or main triangle. This is important because the idler then stays in a fixed position relative to the pivot throughout the suspension travel.

This idler pulley is attached to a member of the suspension linkage, so that it moves relative to the bottom bracket and the rear axle, as the suspension is compressed.
Thanks for clarifying that!

Front page has something, guessing more onto the actual product page later today

I hope sizing isn't weird. Current reach at 462mm is pretty good for a medium. I'm 5'10 and usually between sizes so hopefully medium doesn't shrink..
TL;DR: idler on one of the suspension links, applicable for 4 and 6-bar suspension designs. i-Track does not cover idlers on the main frame or the swingarm of a single pivot.
That's why Norco has it (chainstay of a 4-bar), ditto for Intense and Forbidden doesn't have it (single pivot). Kavenz had a similar layout to Norco and moved the idler to be concentric with the pivot of the chainstay, thus idler being 'mounted to the main triangle' (not moving relative to it), thus skirting the patent.
yea, i don't get it either. but that ship has kinda sailed unfortunately. at least it looks like there is a substantial surface area on the face where the hub will interface, ala SRAM torque caps (are those even still a thing?)
Present on all Rock Shox forks, but now there are screw on spacers for standard hubs included in the box.
It's now gone from the front page too, guessing it's permission issues w/ the site...

Ya that weight is tough. I get its coil, but my EXT might as well be coil and its significantly lighter. I'm willing to bet a Zeb or 38 with a coil conversion is significantly lighter too.
yea, i had a bit of knee-jerk reaction to that weight before i realized it was coil (which was kind of dumb of me). a fox 40 is about an ounce or 2 heavier.
