FORCE Basic S4.6 Stem 31.8mm | Reliable Aluminum Road Bike Stem

Upgrade your road bike´s cockpit with the FORCE Basic S4.6 Stem, a component engineered for reliability, precision, and a perfect fit. Designed for the discerning road cyclist who values performance and durability, this stem provides the solid, dependable connection you need between your handlebars and fork. Whether you´re looking to fine-tune your riding position for greater comfort on long endurance rides or seeking a more aggressive, aerodynamic stance for competitive events, the S4.6 offers the versatility and strength to elevate your cycling experience.

Crafted from a robust aluminum alloy, the FORCE Basic S4.6 strikes an ideal balance between strength and weight.

The sleek, minimalist design is finished in a modern matt black, allowing it to seamlessly integrate with the aesthetics of any road bike, from classic steel frames to contemporary carbon machines. Its compatibility with the industry-standard 31.8 mm oversize handlebars and 1 1/8” fork steerers ensures a straightforward installation on the vast majority of modern road and gravel bikes. At a length of 70 mm, it offers a quick and responsive steering feel, ideal for criterium racing or navigating technical routes. Despite its solid build, it maintains a competitive weight, ensuring it won´t hold you back when the road points uphill.
