This. Your crank is fine. A nice set of wheels make a big difference. If you really feel you need a new crank, just jump on eBay and get a Force crank. Funny that Cannondale did that. They used to do a Force crank on the bikes with Rival. But then again, they also have a habit of putting rubbish wheels on their lower level bikes.
