The Éclat Bios Slim is the leanest offering in the Bios range, designed for riders who demand a low-profile aesthetic and maximum weight savings. While many "slim" seats on the market are prone to structural failure due to their thin profiles, the Bios Slim utilizes Éclat’s exclusive Nylon/Fiberglass injected base. This proprietary mold was developed over two years to reinforce the traditional weak points of Pivotal seats—the nose and the rear—ensuring that "slim" doesn't mean "fragile."
By stripping away the excess padding found on the Mid and Fat versions, the Slim seat provides the most clearance possible. This is the preferred choice for park and transition riders who need the seat to stay out of the way during complex air maneuvers, as well as racers looking for a lightweight, high-strength perch that won't hinder their movement around the bike.
Exclusive Reinforced Base: Features a custom-engineered internal structure that has been laboratory-tested to outperform generic seat bases in both impact resistance and longevity.
Minimalist Slim Profile: Designed to be as low-profile as possible, offering maximum clearance for your legs during lookbacks, inverts, and technical air tricks.
Ultra-Lightweight Construction: At approximately 283g, this is one of the lightest high-strength seats on the market, making it ideal for performance-focused builds where every gram counts.
High-Tension Cover: The Black cover is tailored tightly over the minimalist padding, providing a sleek, modern look that resists bunching and tearing.
Pivotal Mounting System: Compatible with all standard Pivotal seat posts, allowing for easy angle adjustment via the single top-access bolt.
Clean Top Patch: Features a recessed rubber patch for the Pivotal bolt, ensuring a smooth surface that won't snag your clothing or irritate your legs.

The Park & Trails Rider: If you need your seat to be as unobtrusive as possible while you're in the air, the Slim profile stays completely out of the way.
Weight Weenies: The ultimate choice for riders looking to shave weight from their build without sacrificing the strength of the seat base.
The Clean Aesthetic: Perfect for riders who prefer the "pro" look of a thin, streamlined seat that complements the lines of a modern BMX frame.
Barspin Specialists: If you rely on "pinching" the seat with your knees for barspins, you may find the Slim profile too narrow. The Éclat Bios Fat or Mid versions are better suited for leg-grip.
Comfort-Focused Cruising: With very minimal padding, this seat is not designed for long periods of sitting. If you commute on your bike, you will likely prefer a more cushioned model.
Because the Bios Slim has very little padding, the strength of the base is what does all the work. When installing, make sure the splines on your seat post are clean and marry up perfectly with the seat base before tightening the bolt—this prevents any "rounding out" of the interface during heavy bails. To maintain the stealthy black look, a quick wipe with a damp cloth after a dusty session is all it needs. If you're looking for the ultimate lightweight setup, pair this with a 7075-T6 alloy Pivotal post!
