I haven't used many seatpost shims in my life ..but this was rock solid
Does exactly what it needs to do - fit a smaller seat post into your downtube. Would reccomend.
Wow what a difference this seat post makes on rough terrain. Does take up some height but man does it work.
The Cane Creek Seatpost are great quality, works superbly
