BikeYoke Willy MAX 34.9 mm dropper post protector

BikeYoke WILLY is a rubber seat tube clamp seal that prevents dirt from entering the frame. For seatposts with a diameter of 34.9

The worst is squeaking, so it’s no wonder you see old inner tubes wrapped around seatposts and seat tubes. This helps keep dirt and mud out of the frame when you’re riding in muddy conditions. You’ve probably noticed your seat clamp covered in 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 frame with the larger 34.9mm seattube and seatpost diameter.

WARNING:

The function, appearance and even the lifespan of the installed WILLY seal depend on the shape of the saddle sleeve used.

Most saddle clamps can be threaded through, however, many of them are large, have sharp edges and screws, do not fit into the WILLY seal, it does not fit well with them and can be damaged. We cannot guarantee its durability with these clamps. That is why we produce the ultra-low SQUEZZY clamp, which fits exactly into the inner groove of the WILLY seal and we recommend it for perfect function.
