Why upgrade the seatpost on a Factor?
Factor frames are engineered to an extremely high level, but like most brands, the stock seatpost is designed to be conservative and durable across a wide range of riders and use cases.
Darimo treats the seatpost as a structural performance component — optimised for weight, stiffness, and precision rather than mass production. The result is a meaningful reduction in system weight without altering fit, ride quality, or reliability when installed correctly.
This upgrade makes sense for riders who already know their position, respect torque values, and expect premium carbon to be treated properly.
Compatibility

FAQs
Are the Ostro VAM and Ostro VAM 2.0 seatposts the same?
No. Each frame generation uses its own dedicated seatpost. Select the version that matches your frame.
Straight or 15mm setback — which should I choose?
Straight suits aggressive, forward positions. 15mm setback suits a more traditional road fit. Choose based on your established position.
Is this seatpost compatible with Shimano Di2?
Yes. The seatpost supports internal mounting of the Shimano Di2 battery with clean internal routing and no rattle.
What if I’m running SRAM AXS?
No issue. The seatpost installs normally with no internal battery required.
Can the seatpost be cut to length?
No. Darimo seatposts are not designed to be cut. Cutting may compromise structural integrity. Correct length selection is essential.
Is this suitable for everyday riding?
Yes — provided correct torque values are respected and installation is carried out correctly. This is a performance component, not a beginner part.
