FAQ
Can I use a shim to adapt to a non-round or "aero" seatpost?
Unfortunately, the seatpost shim is only designed to adapt our 27.2mm round seatpost to other larger round seatpost diameters (for example, 31.6mm or 30.9mm). If your seatpost is oval or "aero" shaped, then both of our seatposts are not compatible with your bicycle.
My bike has a 25.4mm seatpost. Do you have a shim for that size?
The short answer is no. Both of our seatposts are only available in 27.2mm diameter. Since that is larger than 25.4mm, it is not possible to use a shim to adapt the seatpost to your frame.
