Darimo T2 25mm Setback Seatpost

The ultimate upgrade for cyclists chasing unrivaled lightweight performance: meticulously engineered and hand-built, the T2 25mm SB sets a new benchmark in weight reduction without cutting corners on precision.

At just 115 g (31.6 mm diameter, 400 mm length), this carbon seatpost combines exceptional weight savings with a sleek, race-ready look. Built for a wide range of cycling disciplines, it's the choice for riders who want to shave grams without giving up performance. This listing covers the 25 mm setback version specifically — Darimo also offers the T1 Loop (zero offset) and the T2 15mm setback, so you can match the seatpost to your actual position rather than the other way around.

Tailored Strength: Asymmetrical Lamination

Made from bidirectional and unidirectional carbon fiber, each seatpost is hand-laminated in a carefully studied asymmetrical pattern. Guided by Finite Element Analysis and destructive testing, this lamination puts strength exactly where it matters, achieving a genuinely record-low weight without compromising safety.

Finish Options

Choose from 3K Gloss, 3K Matte, UD Matte or UD Gloss. Matte versions carry Darimo logos in matte black; Gloss finishes feature a brighter look with white and red details. Darimo avoids clear coats and varnishes, letting the natural carbon texture shine — small voids may be visible due to the artisanal process, making every piece genuinely unique.

Customized for You, Guided by Cicli Corsa

As official Darimo partners, Cicli Corsa provides expert guidance through the customization process. Order a personalized length, or request a reinforced version (recommended for riders over 90 kg), which adds less than 15 g at 400 mm — the right balance of lightness, strength and rider-specific safety, not a one-size-fits-all compromise.

Safety Beyond Standards

The T2 exceeds ISO 4210-2 safety certification, proven reliability and durability that makes it a trusted component for road, gravel and MTB riders alike — not just a lightweight upgrade, a safe one.

Artisanal Excellence: 100% Handmade

Every Darimo T2 seatpost is handmade in Spain, reflecting the brand's commitment to craftsmanship and innovation. Each piece is genuinely one-of-a-kind. Order your Darimo T2 25mm SB Seatpost today through Cicli Corsa and put one of the lightest seatposts available under your saddle.
