I bought one in November and it is the best road bike I have owned or ridden. Really comfortable and responsive when acclerating hard on the cranks.
Can’t reccomend it enough to be honest. For the monet I think you would have to go some to beat it. I also looked at the Ribble Grand Fondo but opted for the Planet X on the basis I have nothing but good experiences with On-One, scandal frame, inbred frame, clothing, carbon forks etc.
Go for it!
