Darimo T2 25mm SB Seatpost


We introduce the Darimo T2 SB  with 25mm setback  Seatpost in which we have studied and designed all its parts to achieve a record weight (115 g in 31.6mm diameter and 400mm lenght).

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.

The connection parts with the saddle have a large contact surface without sharp edges so it is suitable for any type of rails, including carbon rails 7 * 9mm.

To choose the proper seatpost length, measure the length of your seatpost out of the frame. Measure from seatclamp to saddle rails. Then choose the appropriate size in the following table. If there are two possibilities it is recommended to take into account the variation and use of the bicycle by different riders. If you need a larger or smaller size, please contact us to prepare a seatpost as up to 500 mm or even longer.
