I heard/read this too.

I've been eyeing up the 2011 Allez Comp for quite a while now (now that I know my budget won't stretch to a Madone 4.5), but I've recently discovered I can purchase a similarly specc'd Ribble carbon for the same price (£1100, full 5700 105) so I don't know any more :/ People who know what they're talking about at my club keep pressuring me to get a carbon, but considering I've never ridden either an ali or a cabon, I really haven't a clue which to choose! Power transmission is what I most care about, really....
