I find pricing very very difficult. Mad prices appear and people pay them. Then lovely things sit there unsold.
My view is that if I am happy with the price and the buyer is happy then we’re all good.
I have advertised my 853 with aluminium Girvins for half what you are asking. I still have them. But the Carbon legs are very sought after - so I would say you are on the low side, and a buyer will be happy and you will be happy. That’s a Good Thing. It’s a lovely bike, and at 350 someone should smile when they get it.
