Nice lovely frames those I reckon thats got to be worth £350-£400
They are nice, and still very very quick as far as short travel XC bikes go, but that pricing is a bit optimistic I think…
These tend to go for between £200 and £500 as full bikes depending on condition and spec.
I’ve seen and XT/XTR’d top level one go for £650, but I’ve also seen a basic deore spec’d one with a worn shock sell for £150.
I’m pretty sure the last of that design Scalpel were 2007/2008, not sure what year that one is, but even assuming it’s on of the last (paintjob suggests it is) it’s still a 7-8 year old frame, of a very specific nature/intended use, and for an obsolete (in XC 😉 ) wheel size. I’d still have one though at the right price and in my size!
So make of that what you will, as usual depends on condition more than anything.
