Steel coil.

Size 8.75x2.75.

Anyone know the weight? I have been searching but can't find anything. I want to know how much difference it will be compared to a DHXAir (450g).

 

[bear]

dunno about that size, but the 7 7/8 x 2 1/4 that I have, with a 650# steel coil (manitou coil) weighs in at 2 lbs 10 oz. The shock body by itself was 14 oz.

 

[William42]

I'm sorry I don't remember the exact weight of mine, but I think it was in the range of 960g for 8.75x2.75 with a 450lb marz steel spring.

My 7.8 x 2.25 with 300# ti spring is 1/4 lb heavier than my DHX air.

Oh man, I hate imperial measurements. I much prefer metric.

We moved away from those in the UK long ago! Although we still use them in certain senarios.

According to the fabulous wikipedia;
There are 16 ounces in a pound.
A pound is 453.59g.
An ounce is 28.3495231 grams.
A quarter pound (or 4 ounces) is 113.398093 grams.

So if the shock body is about 14oz, that is about 396g. Which sounds about correct.

Lakesnake says his ti spring puts his shock a quarter pound more than the DHX Air 5.0, so that means his shock total should be about 450g+113g=563g (so the Ti coil weighs about 166g).

William42 says his shock with a steel coil comes in at about 960g so the steel coil weighs about (960g-396g) 564g.

Does that sound right?
It says on shop websites that Titanium is about 1/2 of the weight of steel, but these calculations (sorry guys, based on somewhat unreilable data) say about a 1/4 of the weight.
'IF' there is a lot of difference between steel and titanium coils. With a going price for a Ti coil at $200, sounds like a good idea to me!

Except lake snakes is a 7.8x2.25 and the ti spring isn't the right weight, length, size.

yeah, after a quick search through the various Ti vs Steel debates it seems that there is little point to getting Ti.

I might just swap over the DHX air for XC rides and then go to the Roco TST-r for DH days.
cheaper and will work out lighter. (just have to pump it up to stop it sagging to much)

I am still waiting for mine to arrive (been a month now, the shop sent to the wrong customer and should arrive this week), although I need to get the mounting pins as well.

Good thinking on the Ti spring.

But the coil is much better in ALL aspects to the DHXa on that bike, including climbing and XC.

The web is your friend when imperial measurements are not:

I get to try my new Roco tomorrow on the Enduro. :thumbsup:

I am still waiting for mine to arrive, been a month now, the shop sent to the wrong customer! Should arrive this week. The shop is giving me an Easton CNT bar for the delays!

need to get the shock mounting pins, I just asked this question in a new thread, but do you know the size I need for the enduro?

fwiw, i now have same-length roco air tst and coil version.

the coil version is PUSHed, and works fab.

the air version is as built, and shipped, on a Knolly Endorphine.

both now serve on my Quasi-Moto. 2.95:1 average leverage ratio.

i've ridden a ton of miles on the coil, and have only been riding the air for a month or so after I got it from Lakesnake. I have experienced no disagreeable behavior on the air shock, nor any reason to go back to the coil *yet* - but for one reason or another it hasn't been TRULY stress tested (not like the DH-day the coil got in Los Alamos in sept), but AZSF is coming....

FWIW, on my bike, the DHXa suxors. The air pressure has to be soo high for proper sag (280psi for 30%) and it blows through travel quite easily. The Roco runs much better psi for same sag (165psi for 30%) and seems to run very, very well.

Those #'s sound right on. There is a huge difference in steel vs. Ti springs in terms of weight. I bought two ti springs on E-bay. 275# and 300# for $25.00 and $60.00 respectively. Progressive suspension was selling a ton of them. I ride a Knolly Endorphin with a low leverage ratio of 2.4 and I weigh 140#, so I think the lower spring weights were easier to get a deal on. I was the only bidder for the 275# spring. After riding the coil, there was no going back to air, and a weight penalty of 4 oz.over a DHX-A is well worth it.
