Road Mountain Bike 1-1/8 Threadless Stem Extender

The stem riser is made of sturdy aluminum alloy, built to last and resist corrosion. It measures 160mm (6.3 inches) in total length, with a bottom (upper) diameter of 1 1/8 inch (28.6mm) and a steering tube diameter of 25.4mm (1 inch). This product comes in a sleek black color and is packaged as a single unit.

The key feature of this stem riser is its ability to increase the height of your bicycle's handlebar by extending the height of the rod. This simple installation process involves just connecting the riser to your existing front fork rod, making it an easy and convenient upgrade.

The working principle behind this stem riser is its unique locking mechanism. Once the core is inserted into the tube, tightening the screw rod causes the oblique nut and tube to become misaligned due to the oblique opening, resulting in an expansion that securely grips the inner wall. This sturdy, firm, and durable design ensures a reliable and long-lasting performance.

Suitable for most bicycles, this stem riser is specifically designed for use with 1-1/8 inch (28.6 mm) threadless steering gears. Its high-quality aluminum alloy construction provides a sturdy and corrosion-resistant solution that can be used for an extended period of time.

In summary, this stem riser offers a simple and effective way to increase the height of your bicycle's handlebar, making it a convenient upgrade for a wide range of bicycles. With its durable aluminum alloy construction, sleek black finish, and secure locking mechanism, this product is a reliable choice for cyclists looking to enhance the comfort and ergonomics of their ride.
