Hi there, this is my first post.
Date X comes nearer and wan't to be prepared. I want to change the standard seatpost into a parallelogramm seatpost and therefore i need the diameter of the seatpost. If there is anyone with more experience, what lenghts i have to take. I can choose between 350 and 450 mm. Thanks for your help.
Oh, i've posted something anonymus in another section. If it's now the same, how can i change this.
