What does a PUSH tune actually mean and will it invalidate any warranty (not sure they still have one as 2.5 yrs old)?
Also will I notice it, I’m a reasonable rider (I could tell the difference between 34’s and old Float 32R’s) but not a suspension twiddler typically.
They change the shims in the damper to suit your riding weight and type of riding. I’ve had my 34 Perf Elite done, and it’s difficult to say whether the tune alone makes a difference but certainly the setup when I got it back with the PUSH tune and a “best guess” setup based on my weight / bike and riding were better than I’ve ever managed to get it just by incrementally fiddling because I’m not really a twiddler either. (There is probably some confirmation bias in the mix but it really does feel like it’s much better much more of the time). I suspect it makes more of a difference if you’re either much lighter or much heavier than usual. I’m, *ahem* not especially light, if you see what I mean.
They really are helpful, they can sort out a courier to pick up from home and return them (though I’m in France so couldn’t use that) so it works out quite cheap for UK based. Advice on the phone and the info sheet they send back with details of the condition and the setup they’ve recommended are top notch. I am in now way connected to them, just a happy customer.
