Adjustable Bicycle Stem for Road, Mountain, BMX Bikes

The stem is only suitable for 28.6mm (1-1/8") fork diameter. It is NOT suitable for GIANT bicycles with 31.8mm (1-1/4") fork diameter. Please confirm your bike handlebar diameter is 31.8mm (1-1/4") or 25.4mm (1'') before placing your order.

Depending on the thickness of your handlebar, you may need to install a shim. Be sure to use glue on the threads if any loosen up. The stem is made of Aluminium Alloy and has a handlebar diameter of either 25.4mm (1'') or 31.8mm (1-1/4"). The fork diameter is 28.6mm (1-1/8") and the adjustable degree range is -40° to 80°, with length options of 95mm or 110mm.

The stem is easy to install, simply connecting to the original front fork tube. The four-bolt bar clamp holds the handlebar securely in place. Using this adjustable bike stem can help achieve a more comfortable riding position, as the pain in the shoulders, arms, and back caused by the original setup can be corrected.

The stem is sturdy, well-designed, and easily adjusted, making it a preferable alternative to removing the handlebar stem and exchanging it for one with a different angle. This solution allows you to sit more upright on the bike, which is better for your back.

In summary, this bike stem is a practical and effective solution for improving the comfort and ergonomics of your bicycle. Its adjustability and secure clamping mechanism make it easy to install and customize to your needs. However, it's important to ensure that the stem is compatible with your specific bike model and handlebar diameter before making a purchase.
