200LBS/IN coilspring or less wanted for my modified Girvin ODS front shock - anything considered. (I currently have one from a rear Smartshock)

THIS WILL BE THE LAST TIME I POST THIS ADVICE!!!!
Go to your local "spring" place,take your old spring,they will wind whatever you like at a good price too.

hi Kiwi - THANKS [smiley=diaper.gif] [smiley=nod.gif]
[smiley=beer.gif]
As ya know I do all my bike mods on the cheap so I am a little dubious about getting one made custom, when someone in the UK might have one for under a £10. Surely to have one made it would be nearer £30. (since new speed springs used to cost £40 - well from memory I think this was the cost).
Anyway - won't find out unless I check it out so cheers, will let you know how I get on - now where to look. hmmmmmm

??? Your local spring place ???
That's where I go to get fresh H20... Never heard of such a thing in this part of the world.
I'll have to check into that as well :o

i found my Local spring placewhen op sent our trans pacific crosslink with a couple of springs of unknown rate.I looked in the yellow pages and found there was a spring manufacturere just down the road from my work place.He measured and maybe weighed my(OP's) springs and gave me two printouts.At that time he said he could wind anything even a progressive.It may be more than 10 quid but dont forget you are cutting out probably two middlemen AND you are getting exactly what you want.He will even wind what he would call overated(prolly all mtb springs are overrated and save some weight!...
-
Kiwi,
Hat's off to you. Sure enough. There's a spring winder right here in town.
Minimum order is $80 USD so I'll pass. Couldn't I just get a spring from some aftermarket folks for less that that? There must be a way...
-
yeah will somebody somewhere will have just what you need....the trick is to find it.Measure your springs,ie id,wire thickness,length,and number of coils,or at least know the id,length and rate and start looking...and try another spring place,,,sheesh 80 us....
-
Hi all,
$80 - wow - £50ish for a spring?!! man that is more not that far off the price I paid for my frame alone! I haven't had any luck finding a place here in the south of England. Doh!! [smiley=diaper.gif]

Dear Kiwi, or anyone else who might know...
Does a 200#/in spring compress 1" under a 200# load?
Is this what is referred in shorthand as a "200lb" spring?
Thanks,
Will

No.
The 200lb refers to the amount of force required to move it,
if a spring is marked 200x1 this means it requires 200lbs of weight to move it and to be used with a shock with 1" or less of shaft travel any more travel and the coils would bind together before full stroke is achieved (very bad).

-
ummm i thought that the spring rate was expressed in lbs per inch,so to me a 200 spring would be 200 lb per inch..simon does have a point though the spring travel must suit your shock,which is why you need to take your old spring to the winders(if you did go that route)Correct me if i am wrong tho simon!
-
I thought I was right but I must admit you have put doubt in my mind,did find this in mbuk,though even they can get things wrong,

Whhhhhaaaaaat?
They have the sag reference all wrong. If the travel is 1.55 inches(39.37 mm) and the sag is 51 mm, then the sag would blow right through the travel.
Phew, had me perplexed for a while.

,did find this in mbuk,though even they can get things wrong,
See what I mean [smiley=laughing.gif]they also got the amount of turns wrong on the preload but thats another story.

Hi all,
wow - I probably should make sure I have the right lb spring, etc.
I am around 15 stone (210lbs), and running a Vector setup with Girvin crosslink legs (see gallery).
I have an ODS shock on the front and have modified it to take a 350LBS coil spring from a rear smartshock.,
Will a 200lbs x 1 spring be the one to go for? Would a progressively wound one be a good idea too?
dan [smiley=beer.gif]
ps cheers Si for the numbers - will check em out. Anyone else want to do a bulk deal (see if we can get a discount?)
-
the great k2 spring charts suggest a 225 for 190-230 lb rider,although it seems to be accepted that those suggestions are a wee bit stiff......praps a 200 225 progressive would be cool,but of course with a custom spring you could say give me a 212!
-
Hi
Thanks Kiwi [smiley=beer.gif]

found this list online which I'll check out.

Red Alert!
I'm almost the same tonnage as you Dan, and my brand stinkin' new Noleen ELT has a "200" written on the pretty yellow spring. However, when I climb aboard, my static sag is about 50% of the travel!
I think a 225 of 250 pound spring will work way better. Now if I could only find one... ( and a 350 for the back!)

Listen to KIWI!!
I went to the "local spring factory" and got a terrific education in springs along with a catalog and free swag.
The general manager actually had some samples he made for a California bike builder he gave me on the way out... (He couldn't remember the name of the company, but they are tapered, progressive springs. Very cool!)
Here's a guideline on spring labelling - at least for us Yanks: If the spring says 200#, that means it takes 200# to compress the spring 1". I actually got to test a few springs on a massive digital press.
Funny story: I had a spring that I estimated was 200# by standing on it with hard soled shoes. When my 200ish pound bulk squished it about an inch, I thought it was close. The actual measurement was 194.73#. The spring factory guy actually does this out on the plant floor for quick checks! Apparently, it's kind of like wine tasting. He can spot weak spots and poor material this way.
Anyhow, the Diamond Wire Company has a great online catalog and spring calculator. Very interesting stuff - for us geeks. Try http://www.diamondwire.com/
Cheers and beers to you Kiwi.

hi all,
my first response was Simpsons springs and pressing Ltd, who have quoted £45 minumum, most likey more to make me a 225 in/lbs spring! Will keep looking. [smiley=yawn.gif]
cheers,
Dan [smiley=beer.gif]

not getting any cheaper - two more responses.
NEIL SATUR/COIL SPRINGS - "1 SPRING WILL COST £60+VAT/DELIVERED BY POST IN UK .15
WORKING DAYS FROM RECEIPT OF CHEQUE" [smiley=redface.gif]
Craftsman springs - "these springs will cost you #60.00 a pair + VAT #10.00 + VAT 3-4 days
delivery on receipt of your payment". [smiley=upset.gif]
anyone wanna go havles on a spring if I go for the pair from craftsman springs?
-
Junkster why not ask some off our friends on this site if they could assist in sourcing a spring in there neck of the woods on your behalf,or source one yourself from abroad, bound to be a much more reasonable price even with postage especially with the current exchange rate,
Simon.
-
It's not the prettiest solution, but...
Right now I'm using a calibrated die spring on the back of my 856. There are a few pix in the gallery if you want to check it out.
The difference is that it's a rectangular cross section and it's a little heavier than a typical bike spring.
Another difference is that it was very inexpensive. You can get these from any tool & die supply house.
Still trying to find that SPV shock for < $100. Not too likely I suppose.
-
Hi Simon,
yeah, Colin has kindly been looking into it. He is looking into the possibility of a titanium version.
I'll let you know the outcome as he did mention the possibility of getting a bulk discount if anyone else is up for it here on the site.
Nice work on your gallery recently btw. Do you ever have time to go down the pub or spend time with....ahhh what dy'a call them......ahhh family. [smiley=laughing.gif]
cheers, Dan [smiley=beer.gif]

Dan is this any help.
http://www.chainreactioncycles.com//Models.aspx?ModelID=3156
they have a lot of different sizes and weights at a reasonable price.
Simon.

Hi Simon,
cheers, checked this out before but neglected to put the link on this site. Unfortunately I already have the lowest rated spring they do, (350). I am after a 200. Good price for those who want replacement springs though.
cheers,
Dan
