Cervelo Seat Post Mount for Standard Quarter-Turn

Fits like a glove

This is fantastic. It fits smug and looks great. It looks like it is a part of the seat post. If you have a nice bike, buy this instead of something that looks cheap.

Set it and forget it. This mount is great and reliable.

These Garmin mounts are not only super secure, they are works of art! Their light design and perfect craftsmanship, including exceptional packaging, are masterful, outstanding.
