The Shadow Conspiracy Penumbra Jones Series 10 Saddle

The Penumbra Jones Series 10 is designed primarily for BMX and trick-oriented riding, where maneuverability is key. Because of its slim profile and minimal foam padding, it isn't intended for long-distance comfort or extended seated pedaling.

This saddle uses standard 4130 CrMo round rails, which are compatible with almost all traditional railed seat posts. If you are currently using a pivotal seat post, please note that this saddle will not be compatible without a rail-style adapter.

Microfiber is a great choice for this application because it offers a balance of grip and durability. It resists tearing better than standard vinyl and maintains its texture even when exposed to sweat or dirt.

The slim 130mm width is specifically engineered to stay out of your way during technical maneuvers and tricks. It provides enough surface area for control when you need it, but its compact shape ensures it doesn't snag on your clothing or legs while you're moving around the bike.

The plastic shell provides a stiff, supportive base that helps with power transfer and durability. It is designed to hold its shape under impact, which is essential for the type of aggressive riding this saddle is built for.
