Ass Savers Ass Saver Original
The 2016 Ass Saver Original is a mudguard. Designed for just-in-case use, the guard folds under a saddle, unfolding to provide just enough coverage to stop the long wet stripe from rear-wheel wet-pavement spray. A light 15 grams, the guard attaches to standard saddle rails (another model is available for Brooks saddle riders), and can be completely forgotten about till it's needed most. Offered in a range of colors, both bright and subtle.
A good and convenient mudguard.
