Wolf Tooth Components Headset

This refers to an Integrated Standard (IS) headset where the bearings drop directly into the frame. The 52 indicates the 52mm outer diameter of the bearing, and the 40 indicates it is designed for a tapered 1.5-inch to 1-1/8-inch steerer tube.

Black oxide bearings are treated to be more resistant to corrosion and wear than standard steel bearings. This makes them a reliable choice for riders who frequently encounter wet or gritty trail conditions.

With a stack height of only 1mm, this headset is extremely low-profile. It is designed to maintain your current handlebar height and steering geometry without requiring adjustments to your stem or spacers.

Wolf Tooth engineered these seals in-house specifically to balance low friction with high protection. They are designed to keep mud, water, and trail debris out of the bearings more effectively than generic off-the-shelf seals, extending the life of the headset.

Yes, this is an integrated headset designed for frames with integrated cups. As long as your frame is built to the IS52/40 standard, this headset will fit, but always verify your frame's specific headset requirements before installation.
