SR Suntour 6200 is prolly the stock shock on the Specialized Hardrock
steely that you picked up (?)
X 3 .... Upgrade needed ! I don't think i would even bother overhauling an
inexpensive shock like that.
Classic steely hardtail =
.... But, before you spend any more $/time
on it, make sure frame is good (no small cracks) and bottom bracket
bearings are smooth.
If you've got a good
LBS, let them know what you need ....
sometimes they will hook you up with a used part before it gets listed on
CL or ebay.
Cheap/used/damaged steel Stumpjumpers are rare, but if you can find one
that's the same vintage as yer Hardrock, it could make a good parts bike.
Steel is real !
