Ass Saver
There when you need it, gone when you don't.

Ass Saver, the original saddle mudguard or seat fender, fits to the rails of your saddle and requires no eyelets or specific tire clearance, making it perfect for road bikes, track bikes and gravel bikes where a full set of mudguards is not technically possible or desirable. Attaches in seconds without tools and offers basic protection against dirt.
