Cervelo R3 Seatpost Shim

For some reason, the first series of R3 frames that cervelo produced came with the dreaded 32.4mm seatpost diameter. This really limited the choices of seatposts, so this shim was developed. Simply slide the shim down the seattube and you can use any 27.2mm post you desire.


  • High density plastic composition
  • Brings the odd 32.4mm size to a standard 27.2mm
  • Cervelo Part: SHIM-SP-R3-32.4MM
