Cervelo Carbon Rail Seat Post Head 7mmx9mm Rails

This replacement seat post clamp allows a Fizik carbon railed saddle...or any saddle with 7mm x 9mm rails to be installed on a S5, older P3 Carbon and P2 Carbon - plus the 2014 and newer S3 and S2. Unique design offers infinite adjustment to offer the best position for optimal results on your S5, older P3, 2014 S2, 2014 S3 or P2 carbon frame.

If you have any doubts, this basically fits Cervelo seaposts where the saddle clamp sits in a 30mm diamter hole. If your clamp slides along the top of your Cervelo post, you will likely need the Ritchey WCS Carbon 1-bolt Clamp Kit 7mm x 9.6mm instead.


  • Works with S5, older P3, 2014 and newer S2, 2014 S3 and P2C only
  • Durable alloy construction
  • Cervelo part nuber SPH-CER-SP15-Carbon
