Darimo Carbon Seatpost for BMC Roadmachine Aero (27.2)
This version is for BMC Roadmachine Aero frames that use a 27.2 mm round seatpost. It is not interchangeable with the D-shaped Roadmachine seatposts used on other models.
This Darimo carbon seatpost is designed as a direct-fit replacement for the factory 27.2 mm post supplied on Roadmachine Aero builds, focusing purely on weight reduction while maintaining correct fit and clamping.
Why Roadmachine Aero owners upgrade the seatpost
The Roadmachine Aero combines aerodynamic shaping with endurance-oriented geometry. While the frame is already optimised, the stock 27.2 mm seatpost remains one of the few components where unnecessary mass can still be removed.
Darimo’s approach strips the seatpost back to the minimum required material for this application, resulting in a post weighing approximately 95 grams at a 350 mm length.
