Looks interesting. Read about it on enduro magazine and I don't understand what they wrote about the susp. Need to find some time to see if vital is more clear about what moves where and how. Still it's a nice looking bike and it needs no bateries

In hell. Welcome!
The main pivot slides up'n'down on those Fox-made-unicorn-dust-coated rails, that's the new magic, right? I see bushings and seals in that awful video, there's likely to be oil inside that complication, too. Will it have to be serviced every 30 hours like other Fox products? :stosh:

Hey guys-

Thanks for the interest and opinion; I love it when guys aren't afraid to just throw opinions out there - takes balls.

Anyway, there's no oil in there, but we do recommend servicing it with some light grease every 40 hours or so through the grease fittings on the switch mechanism. Total maintenance time takes about 90 seconds.

Regarding mud/crud, and wear issues, a few things to consider:
1. What you essentially have are FOX shock seals and stanchions. How often do you replace your shock seals? Once every year or two (at most) for me, and usually a lot less frequently than that. Considering the seals on our mechanism are only tasked with keeping the elements out (and not also required to keep pressurized oil/air IN as on a fork/shock), we're really comfortable with the design.

2. Our test mules ran 3 years with much more rudimentary hardware and seals, we did a grand total of zero maintenance on them during that time, and there were literally no failures with the mechanism.

3. FOX did some ridiculous testing on this, including one experiment in which they actually submerged it in the grittiest mud we could find and cycled it something like a million (!) times. No failures.

Finally, we experimented with several different shrouds and sealing mechanisms to completely encase the entire area, but unless we added a ton of weight by incorporating some elllaborate labyrinth seal system, we came away with the impression that it's better to just leave that area open and let debris move through. The other option would be to potentially trap gunk inside and have a little pebble rattling around in there, driving you nuts.

In the end, I think you'll be happy with the durability of Swith Infinity.

to be honest once i read "rails" i was turned off.. but with that easy grease port, and the 500+ test hours and such; i say :thumb:

sleek as fuk lookin too

So what exactly is this supposed to accomplish? Or rather-what crappy quality of my current non switch bike would go away?

So if this was in development before the original switch was being sold, does that mean that they were knowingly selling an inferior product just to replace it with this one when it was ready?

Thanks for the reply John.

Is it possible to know in which part of travel what happens to the pivot point? Is it upward till sag and then downward? Wouldn't there be a very rapid shift in chain tension?

Mostly it just makes your schlong bigger and women want you more.

Oh yeah, there's all this crap, too:

From pinkbike:
"What about the Switch Infinity system? Well, its transition from upward to downward movement was seamless, providing a good platform for standing up and sprinting, while also having travel in reserve for the bigger hits. There were no harsh bottom outs, even when using all of the travel on larger jumps and drops. "

From Bike Mag:
"During my first rides on the SB5c, I intentionally sought out some of the steepest, rockiest, most thankless climbs I know to see how it would pedal, and I was absolutely blown away. Regardless of whether I had the Fox Float CTD rear shock in ‘Climb,’ ‘Trail’ or ‘Descend’ mode, the pedaling was precise, and the rear wheel hugged the ground like a mother re-united with a lost child."

From NSMB:
"I was riding like a tool (does this not happen to all of us on the first day out on trails and surfaces we don’t know well?) but the bike was bailing me out."

How does it compares with the Yeti 303 rail system? heavier? stronger? easier to maintain? a 303 Enduro would be really cool IMO.

No more than Apple is selling you an inferior iPhone when they're working on something that's 2 or 3 generations more advanced than the 5S you're using.

We're a tiny company and we get this stuff to the market as fast as we can. Ask almost anyone who's ridden the original SB, and they'll tell you it's one of the best bikes they've ever ridden. The 5c is just better than that.

¡Mira, una ardilla!
EDIT: Just read all JohnP's answers he posted in the time I wrote my previous post. A lot of what I inquired about was answered there, so I'm cleaning my post for thread's sanity.

I get the part where chain tension can be kept perpendicular to the rails/rods in order to minimize chain feedback now. But I still think it looks too steampunk to me.

are you at liberty to tell us if a 140mm+ travel and slack headtube version is in the works?
No, I'm not at liberty to talk about any future projects, but we'd be nuts not to transfer this technology across a variety of models, right? The coming months will be pretty exciting.

Well, considering in real muddy conditions it's normal to go through a set of BB bearings in a day, in the location those are mounted, I'd imagine fairly frequently (not to mention fox tends to have some of the poorest lubrication/seal systems).

MOTO foam and lots of it may be the answer,

looks like it should work well so il give it the usual year to work out the 1st gen bugs.

You go through BB bearings in a day? :eek:

Regardless, I think a BB bearing seal is pretty crude compared to most suspension seals - and while I'm not sure about this particular application, Fox has been using SKF seals on a lot of products recently, which I've found to be quite good.

What's the axle path of this thing? I cannot imagine it being way too different from the SB75.

Btw. why "infinity"? I do not want my schlong to have infinite length if that's what the bike does for me.

I think they meant "depth" so you can disappear in Rabbit's hole if you want.

It's a pretty fancy single pivot.

Let's see an actual axle path graph and the leverage ratio graph.

but HOW MANY SHIMZ?!
Since we know the value can't truly be infinity, we must find the asymptote of the equation f(x) = (frame travel)^2 + (enduro shoe size)*(# shims)*(frame travel) + pi, as the enduro shoe size approaches 13. This will give an asymptote as a relationship of frame travel and # of shims. From there, take your desired frame travel to get the appropriate # of shims required to make it infinitely enduro.
