Is it from the center of the fork clamp to the center of the bar clamp? Does the rise angle affect the length?
I am trying to update an older bike and bought a threaded fork adapter so I could use an old stem that I that I have. Turns out that old stem has a 1" fork clamp and the stem adapter has a 1 1/8" clamp area.
So I either need to get a new adapter or a new stem. But I am not sure what the length of the old stem is so not sure what to order for a new stem.
