A mudguard designed to mount on a bicycle seatpost, compatible with seatposts around 27 mm in diameter. It can be installed on almost any bike; it will also work with slightly thicker posts, and you can add shims for thinner ones. For optimal performance, it’s best suited for tire widths up to 80 mm, though it can accommodate wider tires as well.

The angle is adjustable in two positions and secured with 3 mm screws.

Requires three 3 mm × 20 mm screws along with nuts.
