So I’ll be honest. I love math, but most people don’t share my warm feelings toward numbers. I am going to work on a printable gauge/graphic that will make all of this a visual exercise rather than a mathematical one. Look forward to a sample or two for approval from the BF panel prior to a wider launch to the public (Amazon).
Awesome. Thanks for the quick reply.
Just want to double check that when 35 - 26 = 9 it is still good to go (as it is less than the magic 16mm requirement)
A simple diagram of a head tube and steerer with dimensions labelled (A, B & C etc) plus a simple equation and requirements would be great.
For example,
Steerer Length (A) - Head Tube Length (B) = Excess Steerer Length (C), where (C) must be between 27mm and 45mm.
Excess Steerer Length (C) - Steerer Thread (D) = Excess Steerer Non Thread Length (E), where (E) must be less than 16mm.
I'll leave the diagram up to you 😀
