Wolf Tooth Seatpost Clamp

The precision-engineered Wolf Tooth Seatpost Clamp secures your seatpost and looks good doing it. At the heart of this seatpost collar is our custom self-aligning bolt and anchor. The M5 bolt includes a spherical washer and mates with a cylindrical anchor barrel. This means that threads are always perfectly aligned, preventing binding and ensuring consistent clamping force.  Machined from 6061 aluminum in our Minneapolis facility, the Wolf Tooth Seatpost Clamp is available in seven sizes. Compatibility Clamping Diameter: 28.6mm/29mm 29.8mm/30mm  31.8mm/32mm 34.9mm/35mm 36.4mm/36mm 38.6mm/39mm 39.7mm/40mm 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.
