MARKZERO

MK0 items represent a refined approach to component engineering. All items are made in small batches and feature premium raw materials, labor-intensive CNC machining, and a new design language. The result is components with a refreshed aesthetic and increased performance gains.

A NEW PROFILE

MK0 Stem Caps feature a new design language and an exclusive color to match the MK0 headset. For this new aesthetic, each stem cap spends 3x extra time in a CNC lathe, before undergoing thorough QC inspection, anodizing in the new Shadow Gray color, and branding before it can be installed atop your stem.

Impossibly Thin

You've never seen a stem cap like this. The extra machining and new profile of the MK0 Stem Caps have meaningful gains. Compared to the non-MK0 design, these spend 3x the time in our machines for a weight reduction of nearly 50% without compromising strength and durability.

Stem caps are already one of the lightest components on a bike. The MKØ Stem Cap takes this a step further. These are painstakingly machined to reduce weight while maintaining the integral strength required of a stem cap. The spoked design with visible machine paths align with the complete MKØ collection of components, while being captivating enough to live on a bike independent of other MKØ items.
