The Wolf Tooth MK0 Seatpost Clamp sets the industry standard for weight, security, and performance. When approaching the design of the MK0 Seatpost Clamp, we needed to improve upon already-high marks.
These seatpost clamps require more time in the CNC machine for a new look that saves weight, while also aligning with the overall design language of the MK0 product line. With the milled design and titanium bolt, these save 19% of weight without compromising strength, security, and durability.
Machined from 6061 aluminum in our Minneapolis facility.
Clamping Diameter:
Frames may vary slightly from the nominal diameters due to tolerances and paint thickness. Clamps will fit on frames that are within +/- 0.5mm of specified size. For example, a 34.9mm clamp will fit frames with a seat tube measuring from 34.4mm to 35.4mm in diameter.
Clamping height: 13.5mm
Not compatible with older Ibis carbon bike frames that use a proprietary curved seat collar. Compatible with new carbon Ibis frames that use a conventional seat post clamp including Ripley V5, Ripmo V3, DV9 V2 and HD6.
Note: The seatpost clamp should match the diameter of the seat tube on your frame and not the diameter of the seatpost itself.
