Castelli ass saver

A dry ass is a happy ass, or something like that. If you’re looking for a bit of extra spray protection for your bike but can’t be bothered with heavy traditional fenders, check out the Ass-Saver – soon to be available through Castelli. Originally created by a team of designers out of Göteborg, Sweden, the Ass-Saver is as simple as it gets. The light weight, 100% recycled and able to be recycled plastic fender simply slips into place on your saddle rails providing emergency spray coverage. Remember the cold, wet suffer fest that was Milan-SanRemo this year? In addition to the black unbadged Castelli Gabba WS jerseys, pros were spotted riding Ass-Savers in an attempt to make it even just a little more tolerable.

Castelli Scorpion mudguards will be available through Castelli retaillers soon. Until then you can sign up for their newsletter to try to win one, or pick one up directly from Ass-Saver.

What the Castelli video doesn’t show you, is that when not in use you can fold the Ass-Saver in half and place it back under your saddle until you need it again in the future. Of course, you could also stuff it under your shirt, or in a book, or anywhere else you see fit for safe keeping.


  1. Ive been running one of these for a year or so and they are brilliant. Weighs nothing so perfect as an emergency mud guard that can be hidden away when not needed. They also work supprising well even though they are so narrow.
