Zinn Seat Post Anti-slip Clamp

Seatpost slippage is a common problem for bigger guys. Most seat binders are unable to provide enough torque without breaking the bolt or damaging the seat post itself to prevent the seat post from sliding down into the frame while riding. The heavier you are, the more of an issue this becomes. This new clamp is designed to solve that problem. Simply install this clamp on your seat post just above your frame and torque the bolt to 5nm. Then install your seat post and tighten your seat clamp to the manufacturers torque spec. This is also really good for dropper seat posts. Tightening the seat post binder too tight on a dropper post will cause the post to malfunction. This clamp can be installed on your seat post just above the frame to allow you to avoid torquing your seat post clamp too tight and still prevent slippage.
