The advantage with this solution is that saddles are more uniform in this area and we can therefore provide a proper fit to a much wider range of saddles. Attaching only to the front rails makes the Ass Saver self centering. If you accidentally kick it without noticing, it will strive to regain it's centered position. This is one of the key innovations in saddle mudguard technology and is therefore protected under a pending patent No. SE PRV 1750201-4FLIP-TIP:Using origami principles, the patent pending FLIP-TIP technology allows you to securely fasten the Ass Saver to the saddle with a simple flip of the tip, just like a cycling cap. To unlock, just flip the tip back down and pull backwards. Carbon rails The FLIP-TIP® technology is fully compatible with all types of carbon saddle rails.Saddle bag compability:The new Ass Saver is a lot easier to install with a saddle bag than previous models. While we can't guarantee a perfect fit with all saddle bags, great improvements have been made with considerably less interference as a result.
