The Aluminum Experts: Cannondale forged its legacy in aluminum and CAAD13's SmartForm C1 Premium Alloy is the lightest, most sophisticated aluminum construction available.
Fender up: Fully fender ready. CAAD13 is even smoother, thanks to the newly designed SAVE rear triangle, integrated seat binder and 27 KNOT seat post.
