I'm currently riding a full carbon BMC with Sram red 10 speed and mavic cosmics for about 500 quid. Bargain huntings my thing, I'm not gonna spunk over a grand on an off the peg tiagra bike.
Caad12 framesets now just over 400 from last year so might go that route.
I just wanted a disc caad bike that would take more than 28c. Shame
