The Wolf Tooth Quick Release Seatpost Clamp allows for easy saddle height adjustments. An ergonomic lever on the side of the clamp opens and closes the clamp, which is held together by a bolt with a bronze bushing that lets the rider set the torque. It is friendly with carbon, steel, alloy, and titanium frames. 

Machined from 6061-T6 aluminum in our Minneapolis facility, the Wolf Tooth Quick Release Seatpost Clamp is available in six sizes.  

• Bronze bushing for smooth lever action

• Low-profile ergonomic lever

• Stainless steel bolt with spherical washer

• CNC machined 6061-T6 aluminum

• Secure, precise clamping 


Clamping Diameter:
  • 28.6mm/29mm
  • 29.8mm/30mm 
  • 31.8mm/32mm
  • 34.9mm/35mm
  • 36.4mm
  • 38.6mm/39mm

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 Ibis carbon bike frames.


The seatpost clamp should match the diameter of the seat tube on your frame and not the diameter of the seatpost itself.
