I ride an alloy 2013 Synapse. No complaints from me after throwing Conti II 4000's in 28mm on it. It's a soft bike, really it feels like most of the out of the saddle climbing mush comes from the RS10's, and not really the frame. Wheels feel noodlie, not the bike itself.

I'm keeping myself from spending any more money for awhile (or the next couple of weeks anyhow, right)? So I'll pretend the wheels are good to go.
