Before placing an order, please be sure 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 following the chart indications :
The main tube 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.
Seatpost yokes are made of 7075T6 aluminum CNC machined to achieve smooth edges suitable for any type of rails, carbon rails included. seatpost cradle is made of carbon fiber and it's optimized to allow the best seating for the saddle rails.
The bolts has got M5 diameter and are grade 5 high quality titanium made with forged head and rolled threads. Black anodized color finishing. The front bolt has got a special design head with through holes which allows micro-tuning if required when there isn't enough room to use an hex wrench. The bolts are screwed up onto 7075T6 aluminium nuts. The rounded shape of this nuts allow a correct load distribution without local stressed points.
