How much would be a good price to sell this bike in used but very good condition in the UK?

It's a 2015 Canyon Nerve AL Frame (now called Neuron in newer models). It's in basically flawless condition and has been upgraded a lot. The wheels are almost brand new, the fork is a 2020 160mm travel, and SRAM GX Eagle drivetrain. The rockshox reverb also doesn't have sag.
