Crafted from high-quality forged 6061-T6 aluminum, this stem offers an optimal balance of strength and lightweight performance, making it ideal for serious cyclists seeking reliable bike handling.

Materials and Construction

Made from aerospace-grade 6061-T6 aluminum, the Dimension 31.8 Stem ensures excellent durability and corrosion resistance. The fully forged construction provides increased strength where it's needed most, resulting in a secure and stable connection between your handlebars and fork steerer tube.

Performance & Engineering

Engineered for precision, this stem features a 100mm length with a versatile +/-7 degree adjustable angle, allowing fine-tuning of your riding position for comfort or aggressive riding. With a stack height of 41mm and a clamp diameter of 31.8mm, it offers a low-profile fit that improves steering responsiveness and overall bike control.

Components & Technology

The stem utilizes a 4-bolt handlebar clamp system, ensuring a secure grip on your handlebars while evenly distributing clamping pressure. Compatible with 31.8mm handlebars, it can also be used with 26.0mm bars when paired with optional shim (SM5317). Designed for quick installation and reliable performance, this stem is the perfect choice for mountain biking, road cycling, and trail adventures.

Style & Use Case

Finished in sleek black, the Dimension 31.8 Stem complements any bike aesthetic, from aggressive race machines to rugged mountain bikes. Its versatile +/-7 degree angle provides customizable reach and handling, making it suitable for a wide range of cycling styles and terrain. Whether you're conquering climbs or descending technical trails, this stem enhances your bike's handling and rider confidence.

Innovative & Differentiating Features
