That depends on the spec / age / condition really; if looking at used stuff realistically I'd like a 2017 or later CdF 20 for ballpark £500; any more than that and I'd rather buy last year's model new for £1k as I've seen in one place. Asking prices for such bikes on
ebay tend to be £700-800 (and never seem to sell), while I passed one over at £675 (that sold) and missed another local to me (before I was too familiar with the model range) that went for about £450 and looked like a really good buy on the face of it.
I'd be happy to buy used as it would alleviate some of the anxiety attached to roughing-up a new one, but currently the prices really aren't offering me any incentive to do so. The problem with the new route is that I think "well, if I'm spending that much I might as well get exactly what I want" and talk myself up to the next model up (CdF 30) with its suitably lofty price.
I'd consider an earlier model but that would have to be a fair bit less as 2017 was the model year where the groupset changed to Tiagra 4700 so is a fair bit more desirable in my eyes.
Wow; didn't realise I was sitting on a small fortune!
I saw
this one on ebay with a buy it now price of £725
.
It is pretty much identical to mine, but mine has Shimano 105 groupset and I replaced the fugly original crankset. Oh, and mine doesn't "need to change the crank" (alarm bells are ringing in my suspicious mind). I think the seller might mean the BB anyway, so why hasn't he/she done that simple task?
IIRC, mine was available for about £800 NEW, but I bought mine second hand (on this site) for about half that.
Sadly for the OP, mine is definitely not for sale, but if it was I would probably have expected about £300 (prior to this good news!).
lol - don't worry, you're not
That's a perfect example of what I'm on about though; 4-5yrs old, old groupset, has evidently been to the moon and back and by the owner's admission will need some fairly significant work soon.. all for only around 25% less than you could buy a brand new, last-year's model for (which spec-wise is the same as the current one).
If it brings you down to earth a bit
this one is more realistically priced at £420; has been on there for a while having started at £450 and IMO sub-£400 would be more appropriate.
Here's another silly example - £800 for a 2017 CdF 20, when again you could get last year's model brand new for £200 more. That's been on there for a while too; clearly nobodys interested at the asking price, while generally these bikes tend to move very slowly on ebay but sellers aren't taking the hint on pricing.
They're not all silly mind; it's just difficult to find something in the right size, at the right price locally. Tbh prices are all over the place; I think probably because buyers generally don't do their homework so have less idea of realistic value..
