rear shock

Postby Pesky Jones » Wed Sep 26, 2012 11:52 am

I have recently bought a second hand orange patriot 7+ and am slightly concerned about the rear shock, i have a elastic band round the shock which will get pushed to a half an inch away from bottoming out without any major drops etc, is this normal?

Also first time i have ridden full suspension and was surprised by the whooshing sound the shock makes when compressed...once again, normal?

Cheers

What type of shock? Has the spring/air pressure been set to give you the right sag?

Wooshing sound is probably damping of some sort.

the shock is a manitou 4 way swinger air, and no the air presure has not yet been set, i havnt got a shock pump yet so am unable to set the right pressure. Hoping this is the reason!

Set it up first, you risk damaging it riding it with that much sag! (In fact it may already be too late).
As the damper is doing more work than designed due to what is probably a lack of air pressure, a whooshing sound isn't unexpected.

ok, i have only ridden it once or twice and no heavy riding since i bought it, so fingers crossed not too much damage has been done. I need to get my hands on a shock pump it looks like!

From what i have read, the basic procedure is 2/3rds of my weight in psi into both valves? am i right?

On a side note having a shock called "4 way swinger" is plain hilarious.

I'm not sure i can handle that level of double innuendo outside the crudcatcher.

Nope.

The basic procedure is as much air as is required to get the sag right.


Followed by whatever noodling around the rebound and compression and platform controls need.

I'm not sure if i correctly described the issue, the sag is only about 1/4 - 1/5 of the travel... the elastic band reaches a half inch away from bottoming out after a reasonable drop (1 footish) but this is not a huge drop so i was worried on a bigger drop it may be close to bottoming out...

If the sag is correct, that sounds normal to me. But make sure the sag is actually correct because you may be measuring it wrong. Maybe you're landing a bit rear heavy or the forks are set too firm and aren't taking the correct proportion of the force relative to the rear.

Sorry could you just clarify what the correct way of measuring is? because im just assuming the sag is 1/4 - 1/5 of the visible travel if you know what i mean?

Correct about 20-30% of the full length of the shock stroke, and you should measure it stood in the attack position with ALL your riding kit on, otherwise when you put your full riding kit on you will weigh more and sag more during the ride. Also make sure when you get on to measure it you dont compress the shock past where the sag will be otherwise it'll show more than it actually is (common sense but some do get it wrong).

Dont really understand this bit, I was going to roll the band right up the top, then sit on the bike, then measure the distance between the top of the shock stroke and the band, giving my sag which im hoping is a third or less than my total stroke length?

think he means when you get off the bike to measure the sag, be carefull about compressing the shock even further

if I can possibly say this seriously in a discussion about a 4 way swinger, you'd end up with the rear end being too stiff

first things first download the manual and read it before you damage the shock.

Does it have SPV? is that pressure in tolerance? if it is not you WILL damage or have already damaged the shock.

I spoke to the preivous owner who weighs the same as me, and he said he had it at 250 psi??? sounds a little high?
