Heavier yes. More expensive maybe, depends on how the lugs are made. If they can be made cheaply enough, I could imagine the final production price to be fairly similar to welded frames. As you don't need a welder, don't need to straighten the frames during heat treating, don't need to heat treat them, etc. The production process could potentially be a lot less energy intensive, at least the assembly of it (if the parts themselves are produced energy intensely). FYI, aluminium cars are bonded, not welded.

Sorry, I posted in the wrong thread. Chilcotin will be the next Knolly to get the Gen 6 treatment. Not really a rumor, but 🤷🏽‍♂️

Impacted by heat and impacted by heat a significant amount are different things though. That's a pretty tight spread (looks like single digit percentage difference at bottom of travel) besides the slowest curve which looks like it could have something interesting going on with negative air spring crossover. When you look at how a bike like the Enduro with a mullet yoke would compare to a plain Enduro, the 6% increase in shaft speed is would be comparing 125 mm/s to 133 mm/s. You're going to have essentially the same curve. I would put money on the difference between 125...

Air springs are absolutely affected speed/frequency and adiabatic compression, especially going from very low speeds around 5mm/s up to 75mm/s. This plot is of a DVO Topaz at 100psi and damper removed @ 25, 75, 125 and 254mm/s but didn't have a lower speed run which was a shame because the most change is at those very slow speeds. Bear in mind your shock is under 75mm/s around 50% of the time you are riding! Also important to note that most spring testers use a fixed speed which is simultaneously too fast for pure isothermal compression but not fast enough...

Spring rate isn't really going to vary due to compression speed. The common example of a process that's assumed to be adiabatic is compression in the cylinder of an engine, which can be on the same order of magnitude as a bullet. You'd be hard pressed to create a leverage curve that was so different than heat transfer during compression was notably different between the two. That's not to say heat doesn't impact air shocks, though. Heat building up over time is very real though. Even on a 3min lap during the wet season by the time I'm at the...

@CascadeComponents Thanks for that response! Specifically, what I’m wondering is if the enduro from that post might feel less poppy because, with the higher leverage ratio/lower motion ratio, the adiabatic spring rate would be lower for the compression speeds that the bike normally sees. In your first graph, at 30% sag, the shock would be moving about 6% slower (if...

Take this with a grain of salt because this is a generic spring curve I came up with for an air can. To make the impact of leverage ratio very apparent, this is comparing a 170mm bike that is 30% progressive to a 170mm bike that is 60% progressive. The 30% line happens to be a V2 Megatower. The 60% line is a crazy progressive V2 Megatower. In all cases I am comparing a set up with equal amounts of sag. To be clear that would be crap because the spike at end of travel is unreasonable, but the exaggerated...

@CascadeComponents I was reading your post about the Enduro mullet yoke yesterday in the Tech Rumors thread and what you were saying regarding the non linear change in damping got me thinking about how significant the impact of the reduced shock compression speed would be on the adiabatic spring rate if they were running an air shock. What are your...

I hope the bias in my conclusion was glaring, because I tried to spell it out as clearly as possible. I had an expectation for the Deviate and, to my surprise, that expectation wasn't met when I rode it. I'd love to ride it with an entry level shock to see how the axle path feels with less damping and more suspension bob.

Not at all, they're openly marketing this bike to smaller sized people. Knolly also says this is the first bike to pave the way for their 6th gen designs, meaning we'll likely see the release of bikes that include XL sizing and full 29" wheel options.

I had a guy at work tell me, ironically mere moments after I had read ferrintino’s piece on NSmB https://nsmb.com/articles/the-thief-of-joy/ anyways this coworker drops: what’s wrong with Strava? It’s just like racing whenever you want? as a former racer who worked really hard to achieve my goals and develop a race craft (I still suck) I found this comment sickening. Like it made me sick. Sickening. Like racing is actually lining up. Strava is not racing, and for those that think it could be, goactaully race. Xc, enduro, dh —Fucking race dh people. That’s racing. Strava is masturbation. and now...
