Prologo Raion Review: The Sustainable, All-Road Bike Saddle (2025)

Here’s a bold statement: the cycling world just got a game-changer, and it’s not just about performance—it’s about the planet. Prologo has launched the Raion, a recycled all-road saddle that promises to redefine what it means to ride responsibly. But here’s where it gets controversial: can a saddle made from recycled materials truly deliver the same performance as its non-recycled counterparts? Prologo says yes, and they’re putting their money where their mouth is.

For riders who crave both freedom and fitness, the Raion is a dream come true. It’s designed to handle everything from your daily commute to grueling weekend gravel adventures, blending comfort, versatility, and sustainability into one sleek package. And this is the part most people miss: Prologo isn’t just dipping its toes into sustainability—they’re diving in headfirst with their growing ‘Ride Green’ portfolio, and the Raion is their latest, most ambitious step yet.

Built for Every Terrain

The Raion isn’t just another saddle; it’s Prologo’s answer to the all-road rider’s prayer. Lightweight enough for road cycling, rugged enough for gravel, and forgiving enough for light off-road trails, it’s the jack-of-all-trades in their lineup. Measuring 245mm in length, it comes in two widths—135mm and 145mm—to cater to different body types and riding styles. At its heart is Prologo’s Active Base System, a dual-layer design featuring a central relief channel and lightly padded cover. This setup ensures even pressure distribution, reducing numbness while maintaining stability, whether you’re sprinting or cruising.

The saddle’s compact ‘T-shape’ profile keeps you securely in place without feeling restricted, a modern take on saddle geometry that prioritizes support and movement. It’s a subtle yet significant shift away from minimalism, focusing instead on what riders truly need.

Recycled, Not Compromised

Sustainability isn’t just a buzzword for the Raion—it’s its DNA. Prologo has crafted this saddle using a recycled nylon base, Re-Steel rails, and recycled materials in the foam and cover. Every component is engineered to minimize environmental impact without sacrificing the stiffness, resilience, and ride quality Prologo is known for. They call it ‘sustainability without compromise,’ and for once, the tagline feels authentic. Even as the entry point in their All-Road range, the Raion doesn’t scream ‘budget’—it screams innovation.

Fit Options for Every Rider

Prologo offers the Raion in two fit options to cater to diverse riding preferences:

  • Raion 135 (245 x 135mm): A flatter, narrower design for riders who prioritize freedom of movement.
  • Raion 145 (245 x 145mm): A slightly wider base with extra padding for those who value support and long-distance comfort.

Both models feature the Re-Steel 7mm rail system, keeping the weight impressively low (272g for the 135mm and 283g for the 145mm) while ensuring durability for mixed-terrain use.

Completing the All-Road Family

The Raion joins Prologo’s expanding All-Road lineup, which includes the Akero R and Akero R PAS models (255 x 150mm) and the comfort-focused Akero R 160 and PAS 160. For the gram-counters, there’s also the Feather II grips, made from recycled EVA foam—a lightweight, eco-friendly addition for mountain bikers.

Price and Availability

The Prologo Raion is available now through prologo.it and select authorized retailers for €65. With its blend of performance, sustainability, and affordability, it’s a saddle that’s hard to ignore.
