Please don't think I'm being obtuse but, even at a tenner for the springs (which is less than I paid) this is a £10 pair of forks (after postage)..
They are quite tidy (cosmetically) and bounce as I suspect they should.. they aren't being peddled as NOS or awesome condition or even rebuilt.. they are a cheap set of forks that, imo, look quite cool and kinda retro.
Twisting the knobs didn't undo anything and the tools I would need (spanners, I suspect) are packed in readiness to move house
