Newbie question.
I am using to reach & stack values to control the dimensions.
But if I want to have a horizontal T.T. it changes the H.T. length.
What am I getting wrong ?
Cheers, JB
Horizontal top tube
If you are defining the front end geometry by stack and reach, you'll want to leave that menu selected to lock in those values. This is discussed at: bikecad.ca/toptube_frontcenter. You can then adjust the angle of the top tube by changing the seat tube length. Another thing that ties into this is tube extensions described at: bikecad.ca/tube_extension.
