The Comp III uses standard, imperial diameter, Tange#1 and stock construction, while the International LD uses large diameter Tange #1 with internal lugs. Consequently, they use different seat post sizes.
To properly answer your numerous posts on the subject, we need to known exactly what you have. Given that you are in Indonesia and each market has different model names, photos would be helpful. At the very least, we need to know the outer diameter of the seat tube, the construction method and the tubeset.
Now i use 27.2 but seatpin is to tight like this, maybe the catalague is wrong?
outer seattube diameter is 31.8
