Ritchey Seatpost 1-Bolt Clamp Kit


The Ritchey 1-bolt alloy seatpost clamp kit is a stock replacement kit for Ritchey 1-bolt seatposts. They come in different slot diameters to accommodate the larger diameter carbon rails found on some contemporary saddle designs. The clamp kit includes the main bolt, washer, one threaded and one unthreaded rail clamp.

There are two sizes to choose from - 8.5mm for larger than standard rails and 9.6mm for Fizik carbon. Beyond the diameter size, you will need to select from carbon or alloy - select carbon if you have a carbon shaft post and alloy if you have an alloy shaft post. These clamps only work with Richey 1-Bolt seatposts and cannot be retro- fitted to work with other seatposts.


  • 3D forged and polished aluminum
  • Includes entire clamp assembly
  • Compatible with Ritchey 1-bolt seatposts only
  • Choose rail size
  • 42 grams
  • From $9.88

     John Stebbens : 

    I bought this to go with my ritchey prologic seatpost. I bought the 7x9.6 carbon to go with my Fizik Arione saddle with carbon rails. It fits perfectly. My clamp kit is actually black and not silver like in the picture. It goes with the post and saddle much better than the silver one would. The nm torque adjustment (which happens to be 12nm) is printed on the one side.

    Pros: It fits my Arione saddle and my prologic seatpost.

    Cons: None. It is a well made piece. Top quality here.
