The best place to find the correct seatpost clamp size is on your bike manufacturer's website. Be as specific as possible when searching on the manufacturer's website or on a search engine — include the bike's year, model, material, and other key identifiers. If information can't be found, you can find the correct diameter by using a caliper on the frame. The seatpost clamp should match the diameter of the seat tube on your frame — not the diameter of the seatpost. Another method is to print our Wolf Tooth 1:1 Seatpost Measurement Guide at 100% scale. This guide was designed for both Wolf Tooth Seatpost Clamps and QR Seatpost Clamps. It includes a measuring tape as well as a size diagram that can be used with your existing seatpost clamp. Wolf Tooth machines seatpost clamps in six different sizes and nine anodized colors. Learn more about seatpost clamp measurement and installation below, or click here to shop now.  

1. Gather these materials: This includes grease (or carbon paste/copper paste if you have a carbon or titanium frame), your seatpost, a 4mm hex torque wrench, and your new Wolf Tooth Seatpost Clamp. NOTE: Here we are using carbon paste because the Otso Cycles Voytek is a carbon bike. We recommend carbon paste for carbon bikes and copper grease for titanium bikes.

2. Once you've prepped your seat tube with grease (or carbon paste in this case), you can install the seatpost clamp on your bike. Be sure to line up the slots on your frame to the slots on the clamp (if available). Some frame slots are on the front of the seat tube, others are in the back. If your frame has multiple slots, align the slot on the seatpost clamp with the center of the slots.

3. Install the Wolf Tooth Seatpost Clamp onto your frame. Ensure the clamp's inner lip is fully nested onto the seat tube. Now you're ready to install your seatpost.

4. Install your seatpost to the desired height. Using your frame and/or seatpost torque specs as a guide, set the torque with a 4mm hex torque wrench. A good rule of thumb is to never exceed 6 Nm. If you're using a carbon seatpost or dropper post, you may need to set the torque at a much lower measurement to prevent crushing/binding of materials.

1. Gather these materials: grease (or carbon paste if you have a carbon bike); your seatpost; a 4mm hex torque wrench, and your new Wolf Tooth QR Seatpost Clamp. NOTE: Here we are using carbon paste because the Otso Cycles Waheela C is a carbon bike.

2. Prep your seatpost. Use grease if you have a steel or aluminum seatpost and frame. If the seatpost and frame are made from carbon or titanium, do not use grease. We recommend carbon paste for carbon bikes (as pictured above) and copper grease for titanium. Before applying anything, check your seatpost and your bike manufacturer's recommendations.

3. Install the Wolf Tooth QR Seatpost Clamp onto your frame, taking care to line up the slot on your frame and the slot on the clamp (if available). Some frame slots are on the front of the seat tube, others are in the back. If your frame has multiple slots, align the slot on the seatpost clamp with the center of the slots. Ensure the inner lip of the clamp is fully nested onto the seat tube.

4. Install your seatpost to the desired height and close the clamp. Using your frame and/or seatpost torque specs as a guide, set the torque using a 4mm hex torque wrench. A good rule of thumb is to never exceed 6 Nm. The Wolf Tooth Quick Release Seatpost Clamp memorizes torque, so the torque that you set during installation will always be applied whenver the QR clamp lever is closed. If you're using a carbon seatpost or dropper post, you may need to set the torque at a much lower measurement to prevent crushing/binding of materials.
