So there i was in 2010 getting an £850 Cube Peloton through CTW. Loved the bike, still got it as a matter of fact, but wanted to upgrade after a year or so to carbon fibre. Got a great deal on a light Ridley and proceeded to go no faster than I did on the Cube. Cut to 2015 and I've bought my retirement bike, a Cervelo R3 and guess what I go no faster than I did on the Cube. So with a stable of three which do I most enjoy riding. In truth, all three. The Ridley is a fine winter bike in good nick too. The Cube has seen better days, but is fine as a turbo bike and would still be an adequate bike to commute on. The biggest difference I noticed between the alloy and carbon frames of my first two bikes was in the way they absorbed irregularities in the road. Where I first noticed this was coming out of the village of Finchampstead. Wokingham Borough Council sought fit to put a 5m pinkish corrugated surface on entry/exit from the village which when crossed on the Cube almost threw me off, but was relatively unnoticeable on the carbon Ridley by comparison.
