"But this seat-post has been under-torqued to 4NM with a torque wrench and always used with FSA red carbon paste. On the odd occasion the seatpost has been tightened by hand on the road, its always been re-torqued when back at base camp. It’s been the most molly coddled seat-post I’ve ever taken care of."
