Cannondale Quick CX 4D, 21S - Text Review

At the core of the Quick CX 4D S1 is Cannondale’s SmartForm C3 alloy frame, engineered to deliver lightweight agility and long-term durability. The geometry offers a sporty yet upright riding position ideal for both speed on the flats and control on uneven surfaces.

The bold Acid Lime finish, clean welds, and sleek tubing design add a modern and athletic look. The frame also includes practical features like integrated mounts for racks and fenders, making it city-ready.

The Quick CX 4D S1 comes equipped with a 21-speed Shimano drivetrain, offering a wide range of gears to handle climbs, descents, and fast-paced fitness rides with ease. Shimano Tourney components and trigger shifters deliver smooth gear changes, keeping the ride steady and responsive.

The gearing setup allows riders to quickly gain speed on straight stretches while still offering enough low-end power for hillier terrain.

Comfort is a standout feature of the Quick CX series. The front suspension fork absorbs shocks from potholes, gravel, and uneven surfaces, giving a smoother, more controlled ride.

The upright geometry reduces back and wrist strain, while the ergonomic saddle and grips keep longer rides comfortable. The wide 700×40C hybrid tires add natural cushioning and better stability on mixed terrain.

With mechanical disc brakes at both ends, the Quick CX 4D S1 offers consistent stopping power across all weather conditions. The braking feels reliable and confidence-inspiring, especially during quick stops in urban environments or on sloping paths.

The wide handlebar and lightweight alloy stem provide stable steering, making the bike easy to maneuver through traffic or winding park trails. The suspension fork further enhances control on rough patches.

The bike rolls on robust 700C double-wall alloy rims, designed for strength and smoother rolling efficiency. The hybrid tires feature a tread pattern that grips well on both paved roads and gravel paths.

Cannondale’s comfort saddle is designed to balance support and cushioning, making extended rides feel relaxed.
