2019 Giant tcx slr 1 cyclocross bike

I bought this bike new a few weeks ago with the intentions of using it for winter training but after a couple of rides I've decided that it's not really for me and the money would be better spent elsewhere. The bike has covered around 50km and is in as new condition. I picked up a set of donnelly strada tyres to make it a bit faster on road and gravel so the bike will be supplied with these fitted and set up tubeless, the original maxxis all terrene tyres will also be included.
The bike is size M/L, I'm 6ft tall and it fits me fine.

The cost new for me was £1900 including the donnelly tyres so I am asking £1300, A good saving for what is essentially a brand new bike.
