There's a front spinergy mtb wheel in Bike Workshop, Bristol. Personally I'd never ride spinergys - they known for dangerous and dramatic failures. Only for display, I reckon.
Have a NOS set of SPiN's but won't part with them for less than $800. Where on a bike on a display in a store for years and then removed and put back in the original cartons which I have.
I know a shop who has a front spin that has been hanging around for a while. Let me know what you wanna pay and i'll see if it still true etc. It i new and not been used i think
