Don't forget your rubbers! Creaking is the worst and so it is no wonder, that you can see old inner tubes wrapped and zip-tied to seatposts and seat tubes. This helps keep dirt and mud outside your frame when you riding in muddy conditions. Surely, you´ve noticed your seat-clamp covered in loads of mud after a wet ride. Willy does not more, but also not less than the DIY old-tube-zip-tie-solution, but we think it looks a lot better and doesn't cost a fortune. Willy fits 30.9/31.6mm diameter seatposts and frames. Willy MAX fits the larger 34.9mm Seatpost diameter. Please note: The appearance of an installed Willy greatly depends on the saddle-clamp used on your bike. Our Willy works with most saddle clamps out there and it is very strech-able. However, there are a few (unnecessarily) bulky, edgy, saddle-clamps with long and sharp threads or screw heads, that require a lot of local stretch on some areas of the Willy. This is why we can not guarantee for durability of an installed Willy on one of those clamps.
