I can add a bit more being on the design team for this bike. We can do a better job at calling out the "why" in the short press release. There will be upcoming videos talking about it, but here it is from the design side of things. As bike designers we are constrained by the shape of the motor and battery. We can't change these designs. Riders are wanting bigger batteries (800wh in this bikes case). We also have great demand to fit more shocks, from inline, to the largest enduro and coil shocks. We have to have fork...

Another analogy - trail data or rider feedback is like going to the doctor - they will ask you questions, measure heart rate and blood pressure - thats like data acquisition and finding the symptoms, but getting more answers needs something like blood tests or an x-ray. They might not tell you the actual cause but they give much more information about whats going on

A dyno is a machine to run standardised tests to quantify damper performance. It is not meant to replicate trail loads and doesn't as they load suspension in a very different way. Yes I know electromag dyno's can play back trail data but that's a party trick and not their day job. A simple hand tester is not a dyno because it doesn't measure anything. You can instrument them though and people have. Here's a video showing the scotch yoke end of my Laba 7 dyno in operation: https://www.instagram.com/p/DRis7JOlJme/ Mechanically they are very simple. It's literally a gearmotor turning a...

Thank you for the explanation. It makes all the sense in the world. Not hating on Charlie. I just didn't get it. Cheers, buddy! Mx

4X is DH, but w/ take outs as you weight the front end in less pads.

It is because there is no lift service at that point after the races. There is an episode where he did hike a bike, not sure what bicycle it even was maybe DH, and he said 'yeah never doing this again' They use e-bikes simply to climb the bill, in order to ride it. Maybe Reece can lend him that psycho 200/200 ebike he rides...

A lot of the cost difference on the frame set vs complete sport build is the Super Deluxe Ultimate vs the Suntour Edge shock. There's almost a $400 difference here. If the frameset shipped with the same shock as the Sport build, it would drop the price a good amount. The frameset being spec'd with the higher end shock because most people buying a frameset are looking for something a bit nicer.

Two Fridays ago I saw a Fezzari crew pedaling up the American fork canyon road (alpine loop) at 6am with a bunch of camera gear. I thought they were all on the carbon Timp Peak, but I guess at least one of them was on this thing.

Exactly this.

Oh and the data card at the back of the machine - Typical peak speeds are about 6-8m/s on downhill bike forks, and shocks will be up to around 2.5-3m/s. Most dampers "should" be fairly linear up to those max speeds - some aren't by design, but its rare for the ports to "choke" and start generating excessively high rates at those speeds (despite what some people think). It's more likely that high acceleration causes issues (so very high frequency but relatively low speed) which is why the linear actuator dynos exist.

The machine is basically a motor that turns a shaft, which is turned in to linear up and down motion. The software runs the machine faster and faster, and measures how much force the damper is producing at every point and speed in the stroke. My machine is a CTW "rotary" type dyno with 2 HP and one of the more basic, lower power machines on the market (I think about $15,000 USD today). CTW was born out of a company called Roehrig who pioneered workshop damper testing in the early 90's - many of the older racecar and motorcycle...

A 5 foot huck to flat could probably get you to an inital shaft speed of around 5m/s or 5000mm/s. Simple equation: time to drop = (2*height/g)^(1/2) so sqrt of 2*5/32 = .56s Speed at impact -> speed = time * acceleration or .56 g aka .56*32=17.92ft/s. You can do some more math to figure out how landing slope angle and head angle affect shaft speed, but it's not that important. If a huck to flat gets you to 5m/s i bet you can find bumps that do more. Another limitation of dyno charts: spiking occurs where exactly? Oh, off...

Hand dyno is basically just jerking off a shock. Need a load cell and velocity sensor to be able to generate graphs. The big flaw of the shock/damper dyno is it only tells you what it tells you, it's isolating things. So like in a real suspension system you have the chassis and the spring and those things interact in complex ways. If you watch video tours of fox R&D they seem to maybe dyno whole forks, but looks to be purely vertically which eliminates a lot of the side loading that happens in real life (actually loading the bushings...

Forks frequently see shaft speeds of 4m/s and in general up to about 8m/s (see this video by Vorsprung). Rear shocks see quite a lot slower shaft speeds in general due to two reasons: Leverage ratio and often not being the first in line for the hit.

Just printed a set in ASA. Got a trip next weekend to snowshoe. Gonna try them on the downhill bike, seems the best place for bar ends.

I think it’s just a reference to the fact that Ari has multiple suspension layouts with different aesthetics

What is the relevance of having a ”vertical shock”? Why does it matter? At some point I have heard a newbie say that he is looking for a bike and he had found a Santa Cruz, but he didn't like it because it has no ”vertical shock”. I laughed and explained to him that it doesn't matter so much in the grand scheme of things for a shock to be ”vertical”. Now I see this on my favorite MTB site. Is it a Pinkbike-ish ”wAtEr bOtTLe sPaCe iS sOmEtHiNG i LiVe aNd diE fOr”? Thanks, Mx

You're probably right, but there's no way the parts for a full build cost 800 fun tokens, so there's a disparity one way or another.

Frame only pricing is a psyop to make building your own bike less appealing/practical so you suck it up and buy the full build
