Why doesnt Jan tell me these things :angry:

So if im running my 8.5x2.5 shock with the eccentric adjusted so the shock bolt is in the 3-4 o'clock position how much travel am i getting

W? You mean bottom out bumpers? That isn't progressive, it adds a ton of spring rate at a certain amount of travel, but it won't really allow you to start off with a lower spring rate, at least not to the extent as you can with a pnuematic-valved SPV shock. Plus, with a 5th you can adjust the progressiveness rate, if it isn't quite to your liking you can tweak it,if you want it different for different conditions, you can do that as well. Putting a bigger bottom out bumper on there (like fox did with some of theirs) is a drop in the bucket compared to what you can do with a 5th, which makes it a much better choice for a single pivot type bike.

I'm sorry, I tend to forget most people need bandaids for simple or poor suspension designs. My mistake. In those cases having more tuning options is needed.

If you saw the pic of the bump stop on my proto Push shock you'd know that there is more than just a sudden harsh ramp-up in travel possible with bump stops. That thing was like a second spring for 60% of the travel! If I lived closer to Push I would have pursued more fine-tuning of the bump stop, as I never touch any adjustments on my suspension once dialed. And I never plan to use a shock pump on a non-XC/trail bike, period. Like I said, just my opinion/preference.

assuming its 3-4 oclock when looking at it from the drive side, then you should be getting a little less than full travel, maybe 220mm or so

anyway, remember the old 2000 disco used a 2,25 stroke shock, the newer ones use a 2,5 stroke shock so thats a 9% difference, it never did much for leverage ratio anyway, the bigger effect is that it allows for a shock with more oil.

thats important and relevant to this thread because THE problem with fox shocks was always that the shock is so small and has little oil and is a bit flimsy and is easy prey to sideloading because of its size, not really because of quality or design.

so saying that the push fox is "an avy in fox clothing" is a bit redundant because there never was such of a big difference between a fox and an avy anyway, its just that craig valves them to the rider and can valve them much more aggresively (hence you normally drop the spring rate since the damper is doing more work) because the avy is structurally a lot more powerful and has a LOT more oil in there to dissipate heat and it has a lot bigger damper piston cope with the extra force.

in the end the push fox is indeed like a smaller avy only that the avy is in large part as good as it is because of the size, as ohio says the most interesting part is to see the long term performance of those shocks, how quickly they degrade etc etc.

anyone who has seen how dirty the oil inside a fox rc comes out after just half a season of race use, compared to how the oil inside a jefe or avy looks after even several times that use, will understand what i mean.

id be looking at how the pushed fox`s on flexy, high leverage singlepivots work for the quickest answer to if the push thing is THE suspension upgrade to get, maybe it just plain works!

I had both new links on my Disco back when they first came out in late 01. The first 02 links were not adjustable, thats why the change in early fall to the longer (current) link.

brian, there are three upper links and also three lower links, the latest front end is a bit different from the 02, the latest upper link is actually the same length as the army link but with a slight curve to it.
the 3rd gen lower link is 65mm center of axle to center of axle, depending on what combination you are running, you can use the adjuster with the second generation upper links.

when you had the non-adjustable setup, did you use chainring bolts or rotor bolts on the lower axles?
