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.

Great design, very useful, and resolves the issue of unusable outlets. Great buy!
Color: White, Size: 5FT (2 USB-C)
This is soooooo very cool to use. It allows me to use it in so many other sockets that I could never really use due to their location. It makes it easy to swivel the plug to the position needed. It is sturdy, a good price, and the cord length is just right. I will carry one in each of my backpacks & computer bags, as well as it will replace most of my extensions. The weight was right so that I could put it in my backpacks and having all of the outlets makes it very useful.
