I'm thinking of getting a Thomson Elite Setback seatpost, and have a question for you math/physics wizards. This product description says:
I weigh 380. Should I worry? I know they make them stronger, but I also know the setback will make it more likely to bend.The Thomson seat post has a clamp, head, and upper tube that are strong enough to withstand 350 foot-lbs of torque. The tube will start to yield and bend at the seat tube clamp at about 250 foot-lbs of torque. All other brand posts we tested flew apart at less than 150 foot-lbs of torque.
