Darimo T1 Loop Seatpost | Zero-Offset Ultralight Seatpost

Experience cycling like never before with the Darimo T1 Loop Seatpost, a zero-offset ultralight seatpost built around a genuinely new clamping concept. At an astonishing 90 g (31.6 mm diameter, 400 mm length), it redefines what a race-ready seatpost can weigh.

Zero Offset Design

Built with zero offset (zero setback), the T1 Loop delivers precise saddle positioning for a comfortable, efficient ride — the setup of choice for riders who want a fully customizable fit rather than a compromise dictated by layback.

Revolutionary Clamping System: Dyneema® Loops

At the head of the seatpost, two ultralight Dyneema® loops replace a conventional clamp mechanism, cutting weight exactly where it matters most. Compatible with a range of rail types, including carbon rails (7x9 mm), the system holds your saddle securely without adding grams you don't need.

Tailored Strength: Asymmetrical Lamination

Hand-laminated from bidirectional and unidirectional carbon fiber fabrics, every T1 Loop seatpost uses asymmetrical lamination guided by Finite Element Analysis and destructive testing — strength is placed precisely where the loads demand it, resulting in a record-breaking lightweight seatpost with no compromise on safety.

Exceptional Build Materials

Premium unidirectional and bidirectional carbon fiber fabrics, anodized 7075-T6 aluminum for shaft and barrels, and Ti Gr5 M5 bolts — the T1 Loop reflects Darimo's commitment to quality and performance at every stage of construction.

The Finish

Choose from 3K Gloss, 3K Matte, UD Matte and UD Gloss. Matte finishes carry Darimo logos in matte black; Glossy finishes carry the bright version, in white with red details. Darimo applies no clear coat or varnish, letting the natural carbon fiber weave speak for itself — small surface voids may occasionally appear as a result of the production process, making every piece genuinely one-of-a-kind.

Rider-Centric Customization, Guided by Cicli Corsa

As an experienced Darimo dealer, Cicli Corsa guides you through the full customization process — from tailored lengths to your broader Darimo upgrade plan. For riders over 90 kg, we can arrange a reinforced version on request, adding less than 15 g at 400 mm length.

Safety Beyond Standards: ISO 4210-2 Certified

The T1 Loop exceeds ISO 4210-2 safety testing. While the standard version is recommended for riders under 90 kg, a reinforced version can be custom-built at no extra cost, so the seatpost is genuinely matched to you rather than a one-size-fits-all compromise.

Simple Assembly, Proven Reliability

Follow the provided video or step-by-step instructions for straightforward installation. Respect the torque specs precisely — max 6 Nm for the seat clamp, 3 Nm for the saddle clamps — for a secure, reliable fit.

Artisanal Excellence: 100% Handmade

Every T1 Loop is 100% handmade, a genuinely unique piece built to Darimo's standard of excellence. Order yours through Cicli Corsa and put record-breaking lightweight performance under your saddle.
