The CAAD8 is an aluminum framed road bike, with carbon forks, and a BB30 bottom bracket. The equipment on the bike is a mix of Shimano Tiagra 4600 and Cannondale C4 parts. With Maddux RS3.0 rims and Formula RB-51 Hubs. This triathlon bike is stock with the exception of the Garmin Edge 500 cycle computer and I’ve changed the stock clip and strap pedals for some Time RXS Speed clipless pedals.
