MK0 Seatpost Clamp

What Our Gearhead® Experts Are Saying:

"I spec'd the MK0 Seatpost Clamp across three builds this season, and the titanium bolt alone justifies the upgrade over a standard aluminum clamp at this price point. Torqued to spec with a 4mm hex, it hasn't budged on any of them, and the 13.5mm clamping height gives me confidence on carbon seat tubes where I'm always a little more careful about even clamping force."

The seatpost clamp sits at a structural junction that riders rarely think about until a post slips mid-ride, and the MK0 Seatpost Clamp from Wolf Tooth Components approaches that responsibility with the same obsessive engineering the MK0 line applies to every component it touches. Spending three times as long in the CNC lathe as the standard Wolf Tooth design, the result is a 19% weight reduction that comes from intelligent material removal rather than compromised wall thickness or reduced clamping surface.

The clamp body is machined from 6061-T6 aluminum at Wolf Tooth's Minneapolis facility, while the barrel is cut from 7075-T6 aluminum for added strength at the bolt interface. The M5 titanium bolt is the detail that sets it apart from aluminum-bolted competitors at this weight, delivering a corrosion-resistant, high-strength fastener that torques cleanly to 6 Nm with a standard 4mm hex key and stays there. Shadow Gray anodizing provides a durable surface finish that integrates with the MK0 headset and stem cap for riders building a unified cockpit spec.
