Darimo T2 25mm SB Seatpost: the ultimate upgrade for cyclists seeking unrivaled lightweight performance. Meticulously engineered and expertly handcrafted, the T2 sets a new benchmark in weight reduction and precision design.

Weighing only 115 grams in a 31.6 mm diameter and 400 mm length, this carbon seatpost combines exceptional weight savings with a sleek, race-ready aesthetic. Designed for a wide range of cycling disciplines, the T2 is a highly sought-after choice for riders aiming to minimize bike weight without compromising performance. This listing refers specifically to the 25 mm setback version. For riders interested in other configurations, Darimo also offers the T1 Loop zero offset and the T2 15 mm offset seatpost.

Tailored Strength: Asymmetrical Lamination
Crafted from bidirectional and unidirectional carbon fiber, each seatpost is hand-laminated with a carefully studied asymmetrical pattern. Guided by Finite Element Analysis and destructive testing, this unique lamination process ensures strength where it matters most, achieving record-breaking low weight while maintaining maximum safety.

Finish Options
Choose your preferred finish: 3K Gloss, 3K Matte, UD Matte, or UD Gloss. In the matte version, Darimo logos appear in matte black, while in the glossy finish they feature a brighter look with white and red details. Darimo avoids using clear coats or varnishes, allowing the natural carbon texture to shine. Small voids may be visible due to the artisanal production process, making each piece truly unique.

Customized for You – Guided by Cicli Corsa
As official Darimo partners, Cicli Corsa provides expert guidance throughout the customization process. Riders can order personalized seatpost lengths or request a reinforced version (recommended for cyclists over 90 kg), which adds less than 15 g in a 400 mm length. This ensures the perfect combination of lightness, strength, and rider-specific safety.

Safety Beyond Standards
The Darimo T2 exceeds ISO 4210-2 safety certification, proving its reliability and durability. This makes it not just a lightweight upgrade, but also a safe and trusted component for road, gravel, and MTB riders.

Artisanal Excellence: 100% Handmade
Every Darimo T2 seatpost is handmade in Spain, reflecting the brand’s commitment to craftsmanship and innovation. Each piece is one-of-a-kind, offering unmatched quality and attention to detail.
