Kalloy Uno Stealth Stem

7050 T6 aluminum is a high-strength alloy that allows for a thinner wall thickness without sacrificing structural integrity. This material choice is what enables the stem to be exceptionally lightweight while remaining stiff enough for high-performance riding.

By using CNC machining to vary the thickness of the stem's internal walls, the design removes material where it isn't needed and reinforces areas under high stress. This optimizes the strength-to-weight ratio, ensuring the stem is stiff where you need it for handling and light where you don't.

Yes, provided your handlebar has a standard 31.8mm clamp diameter. This is the industry standard for most modern road, gravel, and mountain bike bars.

Yes, upgrading to titanium bolts will shave approximately 9 grams off the total weight compared to the stock stainless steel hardware. While it is a minor reduction, it is a popular choice for riders looking to optimize every gram on their build.

The 7-degree angle provides a more moderate, versatile position suitable for most riders, while the 17-degree angle creates a more aggressive, slammed position. Choose the 17-degree option if you are looking to lower your handlebar height significantly for a more aerodynamic or race-oriented fit.
