Description

The WOLF TOOTH MKØ upper cup was developed for cyclists seeking a cockpit that is light, reliable and visually clean. Part of the MARKZERO range, it benefits from a premium design produced in small batches with a particularly refined CNC machining process. This approach delivers a distinctive finish while improving the overall performance of the component.

Thanks to its SLAMMED design, this upper cup features an extremely low stack height of just 4 mm, promoting a lower riding position. Compared to the brand's Premium models, this design achieves a 44% weight reduction without compromising robustness or durability.

Made in the USA at the Wolf Tooth workshop in Minnesota, it is machined from 6061 aerospace aluminium, renowned for its excellent strength-to-weight ratio. Its exclusive aesthetic highlights the CNC machining marks and the Shadow Gray finish, signature of the MKØ series.

Protection against the elements is ensured by several sealing technologies, including an O-ring around the fork steerer and a custom-moulded upper seal effectively protecting the bearing. The cup is supplied with an Enduro Stainless Steel bearing, an upper cover and a specific hollow bolt to ensure lasting, smooth operation.
