Darimo Carbon Seatpost for BMC TwoStroke (up to 2020)
This version suits BMC TwoStroke frames produced up to and including the 2020 generation. For these XC hardtail frames, the seatpost remains one of the most effective places to remove weight without altering handling or frame characteristics.
This Darimo carbon seatpost is designed as a direct-fit replacement for the factory seatpost used on TwoStroke models up to 2020, with full compatibility and no changes required to the frame or clamp.
Why TwoStroke owners upgrade the seatpost
The BMC TwoStroke is a focused XC race platform. BMC spec a robust seatpost designed to suit a wide range of riders and trail conditions. Darimo take a more targeted approach, reducing the seatpost to the minimum material required for this specific frame generation.
The result is a seatpost weighing approximately 95 grams at a 350 mm length, delivering a meaningful reduction in total bike weight for cross-country builds.
Fit and configuration
- Straight offset
- 11.5mm setback option available
Both configurations are designed specifically for the seat tube profile and clamping system used on BMC TwoStroke frames up to 2020.
Design intent
This seatpost is designed to be used exactly as supplied. It is not designed to be cut or modified. If you have any questions around fit or compatibility, get in touch before installation.
