Here you have the solution. Now you can change your original not round seatpost and remove weight in one of the most important places of the bike. The weight removed in seatpost and saddle is very important as it’s far from the ground, then the pendulum effect is reduced drastically.

The main post is made of carbon fiber 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 fiber layers. The layers arrangement is obtained after finite elements analysis and destructive testing.
