Price?
Just my 2p worth, but you might be best to simply advertise this as a sale rather than a swap.
Only saying that as TT bikes are somewhat of a niche, and while I can see someone wanting to buy one, I can't really see a swap on the cards TBH.
Good luck though, great looking bike
PS: are they the pig to ride that everyone says they are? I've always fancied a go on one but I know I'd never do one justice TBH
