I’d say £40 for a used headset even a ck is about right
40 quid for a CK is still low, you put that as the maximum of your suggested price range. Ive never seen a CK go for £30, and at £45 they get snapped up.
and £35 is about the going rate for a 27.2 Thomson post
it is, and again you put it as the maximum of your range.
So yes, as someone whos bought and sold loads of stuff on the classifieds (pretty much built my hardtail off it) I’m suggesting your valuing of his stuff is low, as even you are now admittng the prices you quoted as maximums are more like averages. Your Pro 2 valuation is bang-on, though, £150 seems to be the going rate with only small variations depending on rims.
Only posting for the same reasons you are, offering opinion based on experience to help the OP, but if someone listed a CK for £30 theyd get their arm bitten off. And it’d probably get re-sold on ebay for £50+.
