Goldtec/Mavic fixed rear wheel

Hi all,
Up for sale is a fixed rear wheel I won't be using after aiming to use it in a track frame, only to find out that it's axle is set up for road bike use and can't be respaced without buying a new axle...
The rim is a de-stickered Mavic Open Pro SSC (with older decals judging by residue left by them) and it's laced to Goldtec fixed/fixed hub. Mechanically, everything is in excellent condition and the rim has had no brake wear due to only having been used fixed. There's an unbranded cog fitted and the tyre is a Vittoria Zaffira Pro one. All threads are good. Besides the missing decals, the only thing to mention is that one of the Goldtec specific track bolts has had its end noticeably scuffed, but of course this doesn't effect function. The hub is set up for standard road bike compatibility (130mm OLN) but there's the option of buying Goldtec track sized (and other) axles for £30, since it's not possible to respace the axle in the normal way...
The price is £50, but I'm also willing to consider a part-ex with cash deal for a nice track 1/8" 144bcd chainring.
Collection will be from NW London (Hendon) or I can post at cost.

Also looking to trade the wheel for a nice track/flip-flop rear with standard track bike spacing or the ability to respace the axle. Or I'd also consider a pair of wheels where the rear one meets the above criteria, for a straight trade or part-ex with cash either way. Any offers considered, except for hugely deep rim efforts or those wheelsets with the coloured rims etc...

No interest on here so will be listing on eBay when I get a chance. Thread closed.
