This seatpost came with the frame, bought in Aug 2025, bike build was completed in Oct. It has been used for 6 months but due to winter the actual mileage is low, around 500 km. I am selling because I changed to the -10mm setback. Original length was 380mm, was cut to 330 mm during the bike build by a professional. Comes with battery holder for Di2 and clamp of course. Clamp can support both 7x7 and 9x9 rails. Please note the seatpost can only fit in Evolve Cima frame, it is not round shape.
