The last pair i bid on ebay went for £75, but they were all bar new. I think some sold on here for £50, but again tbh, slightly better condition.
The xc pro stuff seems more popular, but even then there's a lot of chancers on ebay asking stupid money....and NOT getting it

. Like £600 for a pair of xc11 bear traps.
Last xc pros i bought were a bit tatty at £45....i would humbly suggest these are worth £40 ish, plus a bit of post to the right buyer?
Just my thoughts though......
