[Closed] Sorry - Valuations please?

2 bikes I'm not using. What is a reasonable price to ask for them please?
Planet X Full Monty gravel / CX bike. Nearly new, got a brand new pair of Mavic Crosside wheels, tyres and cassette.Has 11 speed shifters, but running as 1x10 speed as the wheels wont take an 11 speed cassette. Used for 5 CX races, and has sat in the shed since.

Carrera Titan carbon framed rigid MTB. Exotic ally forks, Hope hubbed 26" wheels, disc braked, hope at the front, alixir rear, 2x9 ,pretty lightweight, had loads of use (my lockdown bike). Around 10 years old, still rides lovely. I think the value of this may not be worth selling it.

Thanks.
