The new Darimo T1 Loop seatpost with an awesome and outstanding weight of just 117g in 31.8mm diameter and 550mm length.
 
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 saddle clamping system is made with Alumnium Dyneema® loops. That makes a very important weight reduction on the head of the seatpost / clamping system. This system is good for all kind of rails, including carbon rails 7*9mm.
