Sunlite Adjustable Quill Stem

This stem is designed for bikes with a 1-1/8 inch quill-style steerer tube. Before purchasing, verify that your bike uses a quill stem rather than a threadless system, as they are not interchangeable.

This model is compatible with handlebars that have a 25.4 mm clamp diameter. Please measure your current handlebar center to ensure it matches this specification.

The stem offers an adjustable angle range from 0 to 50 degrees. This allows you to fine-tune your riding position from a more aggressive, aerodynamic stance to a relaxed, upright posture.

Yes, the two-bolt clamp system is designed to provide reliable stability for commuter use. It keeps your handlebars securely in place, though it is always good practice to check the bolt tension periodically as part of your regular maintenance.

While the adjustable angle helps you achieve a more upright position, the primary function is changing the angle of the bars rather than adding significant height. If you need to raise your bars substantially, you may also need to adjust the insertion depth of the quill or consider a stem riser.
