The mighty seagull (lat. Larus canus) is the most common gull on the Swedish west coast and a true representative of Swedish Wildlife. We are humbled to live among them and to show our gratitude towards this great animal, we've immortalised a tail feather on a mudguard. This is the best Sweden has to offer.

Front rail attachment
Since 2014 all Ass Saver saddle mudguards attach to the front saddle rails only, ahead of the seat post attachment. 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 mudguard 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 patent No. WO2015036127

Using origami principles, the patent pending FLIP-TIP™ technology allows you to securely fasten the mudguard 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 mudguard 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.

The secret to transforming a flat piece of plastic into a functioning mudguard lies in the pre-folding prior to use. All the scoring lines have been carefully engineered to achieve locking mechanisms, self centering abilities, spring loading and material endurance. Please take the time to properly read the instructions/see the instruction video to ensure the best performance.

I’ve been using the Wing Wing 2 almost 2 months now.

My back is dry, no spots.

On my saddle bag is some dirt but this is not a full coverage fender so it’s ok.

Tail Feather

Excellent, tried and tested on my Specialized Diverge Base E5 frame! This fit...the other one (Fendor Bendor Big x 1) doesn't work...

White feather sweeps away the rain!

Arrived on time and well worth the wait. Bit fiddly to fit the first one but the watched the video and enlightenment was mine. Next two, no probs. Don’t care about colour, pattern etc as can’t see it so don’t care. Nice dry bum!!

Great Colours

Bought two, for mine and my wife’s bikes. Both of our seats are pretty standard although differ slightly. Neither guard fit very well sadly.

Great addition!

Looks good, clear instructions, easy to attach and great value for money! Excellent!
