CYSKY Bike Stem Riser for Mountain Bike, Road Bike, MTB, BMX

The bike stem extension you're considering is an integral unit, not equipped with a separate spacer. The steerer tube diameter it's designed for is 1-1/8'' (28.6mm).

For an aluminum steerer, the recommended torque specification is 8N.m. Simply tighten it enough so the stem doesn't move when riding. No additional spacers are needed - it's an easy installation.

This handlebar stem raiser is crafted from sturdy, rust-free aluminum alloy using 3D forging. The integrated molding results in a smooth, glossy surface and clean, tidy appearance without excessive text or accessories. The simple construction makes it convenient to install.

The package includes the stem riser, a hexagon wrench, and the necessary bolts to attach it to the star nut. The extender body has a glossy finish, simple design, and sleek look. Two bolts are provided to securely tighten the base onto the stem, with a torque recommendation of 8 Nm.

Three size options are available: 120mm, 150mm, and 180mm. Comparison images show the differences in length and weight between these variants. All share the common 1-1/8 inch (28.6mm) fork stem diameter.

In addition to this stem riser, the store offers a variety of other bike stem styles, including 7-degree, 25-degree, 35-degree, 0-60-degree, and 0-90-degree options. Customer reviews for these products range from 4.4 to 4.9 out of 5 stars.

This stem extender is compatible with most mountain bikes and road bikes with a 1-1/8 inch (28.6mm) threadless steerer. The 3D forged 6061 aluminum alloy construction ensures it's sturdy, corrosion-resistant, and high-toughness without deformation.

Installation is straightforward - simply insert the extender into the fork steerer tube, tighten the top bolt, and then attach your stem. This can help elevate your handlebar for better posture, reduced back, neck, and wrist strain, and improved overall comfort while riding.

If you encounter any issues during installation, the manufacturer encourages you to reach out to them for assistance. CYSKY is dedicated to producing high-quality, easy-to-use bicycle accessories.
