Are laidback seatposts hard on frames?

I will be getting one for my TA. Does the Xtra pressure or Pulling back on the seat tube (sorry don't knoe the correct term) Hard on the weld at the junction between the top bar and the seatpost bar?

Any suggestions. I will definatly need one as I am 5'11 and my frame is 18.5.

I am going to get a white laidback seatpost. Any suggestions? Does not have to be vintage.

Re: Are laidback seatposts hard on frames?

it will increase force/weight by the distance it is laidback from the centre line of the frame seat tube.  basic geometry really, force/weight x distance = increased force.  so a lay back of 10cm will increase your efective weight by 10% in normal circumstances and by as much as 50% after a heavy landing as you will have an increase in g-force to include in the calculation. im not saying you are going to land with your butt in the saddle all the time but if you do then thats how much extra force will be applied to your frame.

If you have it inserted far enough you should be ok.Like 1 1/2 to 2 inches below the top tube and seat stays.
