Wolf Tooth Components Premium IS Upper Headset

This headset is designed specifically for frames using an Integrated Standard (IS) 41mm upper bearing cup. You should verify your frame's headset specification—often found on the manufacturer's website or the frame itself—to ensure it matches the IS41 standard before purchasing.

The three-tier sealing system creates a robust barrier against mud, grit, and water, which are the primary enemies of headset bearings. By keeping contaminants out, this design significantly reduces maintenance needs and prevents the gritty steering feel that often develops over time.

Yes, the Enduro stainless steel bearings are backed by a lifetime warranty, which covers failures related to defects in materials or workmanship. While it doesn't cover damage from improper installation or neglect, it provides peace of mind that these bearings are built for long-term reliability.

The stack height options—7mm, 15mm, and 25mm—allow you to fine-tune your handlebar height without needing to cut your steerer tube further or use multiple loose headset spacers. Choosing the right height helps you achieve your preferred riding position while maintaining a clean, integrated aesthetic.

The ultralight stem cap is designed to work with most standard threadless stems. Its integrated spacer and O-ring seal create a secure, weather-resistant interface with the steerer tube, ensuring smooth rotation and protection from the elements.
