He used it on his gravel bike for a while but switched to a zero-offset seatpost. He describes it as not super light, weighing 190g for a 27.2mm diameter with a 400mm length and 10mm layback. He paid around £15-20 and says it does the job.

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. They highlight that the seatpost weighs 180g, which they consider quite light. However, they find the double screw mechanism for attaching the seat to the seatpost somewhat annoying, as it requires careful adjustment to set the seat angle correctly.
