The reviewer discusses the TOSEEK Carbon Seatpost as part of the finishing kit for their bike build. They mention having used this seatpost on their Mason resolution bike without any problems. The reviewer notes that they use a torque wrench when installing and adjusting the seatpost to prevent cracking, despite it being carbon.
