Valuation pls? Planet X Pro Carbon full bike

Hey
Bought this 8 years ago and ridden it about 20 times due to kids, injuries, etc. The usual excuses.
Looking to move it on but unsure how much I should ask for it. If this isn't cool in the forum, feel free to delete.
Thank you!

£300-350

I’ve never got less than £500 for even the crappiest full carbon bikes, you could get at least £600+ I would have thought

If your looking to get into racing and on a budget this would be spot on. Buy this add some decent wheels and you would have a no nonsense racing bike. You might want to sell parts separate and you might get a bit more. (I would be interested in the Planet x calipers!) I would say £500

Thank you. Ebay sold prices seem to bear that out I think

Thanks for the advice.
Never stripped a bike for parts but would be open to it if I knew I could shift each component and not be left with random bits (if that makes sense)

Let me see how I get on with the full bike sale and if it drags on, I'll be in touch!

£400 in the current market if in great condition

Admittedly the second hand market has 'gone stupid' but 105 11sp and even Ultegra 11sp (6800) can be had for commonly for 450-550 at the minute, often with 'upgraded' wheels.

£450 sounds fair

Do you have any photos of the bike? I've got a friend who's after something similar, he might be interested pending photos and price!

Going to give the bike a clear later today so will share some then. Cheers
