Shock pressure for heavy rider

[matthieup]

@Droo,

 

thanks a lot. I shall definitely plan a stop by next time i'm in the area. I'll PM you know to get details

I am also a heavy rider 125kg and often even more.

 

I have Fox front and back, back though is the Dyad pull shock and front 34 mm stanchions, both 130 mm travel.

 

I have always only set up the shocks on sag, 15mm, and then I monitor it with the ring on my rides, to see how much of the travel I use. Full travel is good, then I know I did some proper riding. I have never felt heavy bottom outs, and I do try to be an adventurous rider. We are after all, naturally down hill fit. 

 

My shocks used to be serviced by the ex Fox brand manager, and he was the one who suggested I do it in such a way. I do however stay within the shock's max pressure limit though. If you do bottom out a bit heavy though, you can ask the Fox guys to add a little extra oil, this changes the rebound a bit more, over and above your normal adjustments. 

 

Hope it helps.

Nope. There is no formula, especially not for shocks. Too many variables - linkage curves, leverage ratios, weight distribution, etc etc.

 

Sag setup. The end.

It will work fine on the OP's Bike. I did give him the PDF for Sag Setup.

Ballpark means starting point eg (Ballpark tyre pressure for car tyres  is 2 Bar)

 

And anyway, I wasn't talking to you.

 15% too high

Oh. I always think that the recommended settings are too low. Or maybe I'm fatter than i think I am.

Lol - you know Stoke (droo) is one of the leading (if not the best) suspension set up guy in the country?

he once set up my hardtail to have the most awesome rear suspension ever ... and this all over the phone ... oh wait, that was the other Andrew from Stoke ... and he sold me a Banshee Spitfire Frame

Was that the special "Heavy Boned" limited edition?

is there any other edition

TBH we've never had an issue we couldn't solve with a sag setup. 350PSI in a shock is a LOT of air.

 

When it's outside the parameters on the printed chart on the fork leg - I dunno. The best thing to do with those is peel them off and throw them in the bin. The pressures on those are generally at least 15% too high, probably to prevent damage by bottoming from underinflation plus a massive safety margin, cos America.

Its when the 350 PSI comes out all of a sudden that all of the fun starts. Thats a lot of pressure.

 

Not being a smaller rider myself and having to get my rear shock up to some high pressures has anyone seen a good high pressure rear shock pump?

 

Something with a bit more swept volume that stops me from having to pump about a zillion strokes to get up to pressure.

Specialized makes a track pump that has a nozzle which can be used to pump shocks, which can handle really high psi. Blerry expensive though....

Lezyne make a floor standing shock pump. Possibly my favourite tool. Only does 300psi, but to top it off with a HP version like Rockshox make won't take forever - it's when you've taken the sleeve off to fit spacers that that first 200psi is a real pain in the scrotum.

Weight, like age, is just a number.

 

Except when you bottom out and crack your chainstay.

I call BS when I see it to stop it from propagating.

What have you really contributed to this thread ? "Nothing"

At least I gave him the PDF which by the way if you read it it's quite self explanatory.

I also gave him a Starting Point Which is not "bull****" As you put it.

It's widely used as a starting point.

Suspension Setup is actually not "Rocket Science" and quite easily done if you follow the manufacturers setup instruction on PDF document or Hard copy.

Setting SAG and Rebound is something that all riders should learn to do themselves as most of the cycle shops really have no clue. The answers are all in the documentation that comes from the Manufacturers of the Suspension.

I find that too, did a ride on Sunday running 70psi ( I weigh 70kg) and that was hella soft so promptly pumped up to 90psi
