They’re not worth anything like 800 quid so that has you out initially as someone who bends the truth
They’re white. White massively reduces the market open to you.
They’re an older model rim.
There’s a ding in the rim, on the basis of the the value being stretched, I’d not necessarily believe your comment about it sealing OK.
No actual weights are mentioned. The Olympic rim is aimed at people interested in how much their wheels weigh.
I don’t think including the tyres and or cassette really adds and value or appeal. I’d pretty much see them as freebies, as again, your limiting them further to someone who might want those tyres.
It all comes across to me as a bit of a mish mash with a very limited target market.
And they’re 26er.
That said, its eBay and the real bids and value increases will only happen in the last few seconds.
