Custom designed Carbon seatpost for the Orbea Orca
🚴♂️ Weight Savings Where It Matters
The Orbea Orca OMX frame is already one of the lightest production race frames (around 750 g in size 53). Swapping the stock post for a Darimo can shave over 100 g more, helping you build a true sub-6 kg climbing bike without compromise.
⚡ Perfect Match: Round 27.2mm
Unlike many aero bikes that force you into proprietary “D-shape” posts, the new Orca uses a classic 27.2 mm round seatpost with a hidden wedge clamp. That means you can slot in a Darimo straight away — no weird adapters, no compromises, just plug-and-play.
🏆 Pro-Level Stiffness & Comfort
The Orca is known for balancing stiffness with all-day comfort. A Darimo seatpost enhances that balance: its carbon layup keeps the post stiff under load while still allowing just enough vertical compliance for comfort on long climbs.
🔧 Clean Integration, Simple Setup
Because the Orca’s seat clamp is hidden inside the top tube junction, all the visual attention goes to the seatpost itself. With Darimo’s handcrafted finish, it’s a showpiece component on a bike already designed to turn heads.
👉 Together, the Orbea Orca + Darimo seatpost combo creates a machine that’s lighter, stiffer, and more elegant — a setup worthy of both weight weenies and WorldTour riders.

Handmade in Spain, Darimo Carbon creates some of the lightest and most beautifully crafted components in the cycling world. Every seatpost, handlebar, and stem is a work of art—painstakingly laid up by hand for maximum strength, stiffness, and unbelievably low weight. These aren’t just boutique upgrades; they’re race-proven. In fact, the 2025 XDS Astana WorldTour team rides bespoke Darimo seatposts in the Tour de France, trusting them on cycling’s biggest stage. Whether you’re chasing grams for your dream build or demanding elite-level performance, Darimo delivers that rare blend of precision engineering, featherweight design, and pure cycling passion.
The main post is made of carbon fibre using bidirectional and unidirectional fabrics with an studied asymmetrical laminate to achieve the optimum combination of minimum weight and maximum of resistance.
Each seatpost is laminated by hand to achieve a record weight keeping in mind the strength and your safety. To do this, at each point of the seatpost there are a different numbers and arrangements of carbon fibre layers. The layers arrangement is obtained after finite elements analysis and destructive testing.
