Product Highlights

Truncated airfoil tube shapes decrease drag markedly without adding weight or sacrificing stiffness.

Dependability and accuracy make this 11-speed gear setup an impeccable performer.

Consistent, powerful and reliable braking in all weather conditions, including the pouring rain.

Cannondale's loftiest grade of alloy makes the frame light, laterally stiff and robust.
CAAD13 Ultegra Disc Racing 900 Road Bike 2021
The CAAD road bike range revolutionised aluminium frame design, and the Cannondale CAAD13 is their best alloy racing machine to date. This Ultegra Disc model with Fulcrum Racing 900 disc brake wheels is optimised for speed, and the frame features truncated airfoil tube shapes, creating far less drag than round tubes. It's also highly versatile, offering space for 30mm wide tyres, mudguard compatibility and Speed Release thru-axles, so you can roll on any roads in all conditions. Ride quality and handling are excellent, with the layup keeping weight low and stiffness high for instant acceleration and efficient power transfer. Dropped seatstays bring compliance in the back end so there's no compromise on comfort.
Shimano Ultegra disc components provide powerful stopping on wet and dry roads and the mid-compact gearing configuration offers a wide range of ratios with smooth, reliable and quick shifting. Fulcrum Racing 900 alloy disc wheels are strong and stiff, rolling smooth and fast over a range of road surfaces. The bike is finished with a Cannondale handlebar and stem, HollowGram 27 KNØT seatpost and a Prologo saddle.
