Decrease rate of spring.

If you could actually do this, wouldn't the diameter shrink as you stretched it out?

You will also ruin the spring temper if you heat it enough to stretch it.

Not all spring wire is tempered, but I'm 99% sure that coils like this are.

Thanks after rethinking it i'm just gonna roll with it and maybe get a spring later.

What is the free length and stroke? I have a few older air shocks that might work.

If the shock that you have is a 165 × 35 mm (6.5 × 1.38 inch), I have an old Fox Float that was working fine when it was taken off a cracked frame. Yours for free if you want it. Pick up in Flemington.

I can probably think of like 6 different ways once i start browsing the shop. But off the top of my head. Wedging stuff in the coils then heating it. Hanging weights from it, 2 gear pullers. Put it around and pipe and use the gear pullers on the ends of the pipe and heat it up? Weld crap to the ends then just figure it out as i go. The iron shiek is dead i would have asked him to just pull it apart.

It's this shock. I just needed something to get buy and i guessed it would work. I'd rather use what i have rather than buying new things and throwing stuff out.


With the spring barely seated it's still too stiff. My rebound is fully open


I suppose this is more of a physics question. If you lengthen a shock with a certain amount of coils and diameter, does it get softer?

lol, cheap Chinese shock is not plush, will someone please alert the media 😂

I think you would be better served giving everyone on the forum all the facts. Bike name and type, the original shock info(shock length and stroke) ,bike travel and rider weight.

There are tons of spring calculators on the inter weds, reducing a springs rate on a spring is similar to making a steerer tube longer by cutting it. Springs are just heat treated rods that are twisted into a coil.

Ok the bike is 60lbs i'm 230 but i tell people i'm 210 so not sure if that changes anything.

I never researched spring rates i just bought the middle weight. The shock is going to outlive the frame that's why i wasn't too worried about the quality.

Ok, looks like a racer x, had one…. Had a 7.78x 2.0 shock ….. a shock size that will fit on the medium is a 205x55( don’t know about other sizes)…. A Quick Look and I found this, not sure if you will have piggyback clearance… but it’s a much better shock

I would recommend you loose the the cobbler special and pick up something like this….
