Kalloy Uno 822 Adjustable Quill Stem

This stem is designed for a standard 22.2 mm quill-style steerer tube. It is compatible with both 1-inch and 1-1/8-inch threaded headsets, provided your bike uses a quill stem setup rather than a threadless system.

The handlebar clamp diameter is 25.4 mm. Please verify that your current handlebars match this measurement before purchasing, as this is a standard size for many vintage and city bikes but will not fit oversized 31.8 mm bars.

The stem offers an adjustable angle range from 0 to 60 degrees. This allows you to significantly raise your handlebar height for a more upright, comfortable riding position or lower it for a slightly more aggressive stance.

The four-bolt faceplate makes swapping handlebars much easier than older single-bolt designs. It provides a more secure, even clamping force across the bar, though you should always tighten the bolts in an 'X' pattern to ensure the pressure is distributed evenly.

Yes, the stem includes the integrated quill bolt and wedge assembly required to secure it into your steerer tube. You will only need standard hex keys to complete the installation and make your angle adjustments.
