About this product
This UNO Mountain Bike Stem is a 0-degree ahead stem made from aluminum, designed for various mountain biking disciplines including cross-country and downhill. It features a 31.8mm clamp diameter for handlebars and a 1 1/8 inch steerer tube diameter. The stem comes in a 35mm or 45mm length option and is compatible with Shimano components. Manufactured in China, it includes a 1-year manufacturer warranty and is available for $19.49.
Our take
When looking for a new mountain bike stem, this UNO aluminum option seems like a practical choice, especially for the price. The 0-degree rise is ideal for a more aggressive riding position, common in XC and DH. The aluminum construction should offer a good balance of strength and weight. Just make sure your handlebar is 31.8mm and your steerer tube is 1 1/8 inch to ensure compatibility. The 35mm or 45mm length options provide a little flexibility, but it's a relatively short stem overall. The 1-year warranty is a nice touch for a component in this price range. At $19.49, it's a very affordable upgrade or replacement.
