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.
Features:
- 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.
Compatibility:
- 1 1/8" top (straight 1 1/8" or 1 1/2" to 1 1/8" taper) steerer tubes only
Specification:
Weight (cap + bolt): 4.3 g
Material: Top Cap is 6061-T6 aluminum, bolt is 7075-T6 aluminum
Stem Cap Bolt Torque spec: 2-3 Nm MAX with light grease on threads only. Use a torque wrench.
