This is the Giant 13+ Propel Advanced SL ISP Clamp Spacer Kit. Integrated seatposts are great, but the only drawback is once it is cut, there's no way to go back. Giant has a solution to add height back to a ISP post on the Propel.
- ISP spacers stack in between the seat mast and seat clamp to achieve additional seat height
- Fits 2013+ Propel ISP models only
- up to a total of 25mm of added height available
