ROSE Seat Post Lock

Have you ever had to ride home standing on the pedals, because someone had stolen your saddle and seat post? Inconvenient and expensive! To prevent your bike seat from getting stolen, you can use this seat post security device. The seat post lock comes with an expander that is fitted inside the seat post. The wire attached to the expander is secured inside the tube by means of the bottle cage bolt – invisible, easy and secure!
