SRAM has recalled some of the Red WiFli rear derailleurs. We’ve had some of our customers call us about this situation. None of the Cannondale road bikes sold at Infinite Cycles had any of the Red WiFli derailleurs come installed from the factory. Unless you made an aftermarket upgrade to your bike to add the WiFli wide range cassette and derailleur, your Cannondale is in good shape.
Click the link from Bicycle Retailer below for more information on the SRAM recall.
The short (standard) and mid (WiFli) rear derailleurs are pictured below to illustrate some of the differences. The prominent visual difference between the two sizes is the distance between the two pulleys.
