A bit high on the price side maybe (£ 985) but I've just got myself a Focus Cayo 105 compact. Seems very fast, commuted to work on it today and shaved 13 minutes of my previous best commute time (34 mile round trip) and that was with a couple of stops to fine tune mech limit screws.
Full carbon fibre frame, 105 shifters, brakes and mechs, FSA Gossamer Crank set, 8.6 Kg without pedals.
It just made me want to go faster, weird sensation, really encouraged me to put the power down even when my legs were screaming on the hills. Strangley it was the uphills in particular where if felt faster, maybe I had no choice but to put more effort in as the gearing doesn't go as low.
Only available from Wiggle in the UK but you do get a 7 day trial period during which time if you don't like it or it doesn't fit you can send it back FOC. They've also got a buy now pay in a year's time finance deal as well, costs an extra £ 25 but spreads the pain.
Got good feedback on some roadie forums, good frame and components, just the wheels that let it down apparently, I'm still getting top grips with roadie stuff.
