Looking to reduce weight at the top of your high-end bike? The Darimo T1 Aero Carbon Seatpost is the solution for riders looking to replace their aero (non-round) seatpost with a super-light, high-performance upgrade.
By removing weight in this elevated position, the pendulum effect is significantly reduced—resulting in a better handling, more responsive ride.
Each seatpost is individually hand-laminated using bidirectional and unidirectional carbon fiber, engineered through finite element analysis and destructive testing to find the optimal balance between minimum weight and maximum strength.
The clamping system features Dyneema® loops on straight versions, making it compatible with all rail types (including carbon 7x9mm) while maintaining an incredibly low weight.
Only 95g in the 350mm version – one of the lightest aero seatposts ever made.
