The design thatI am currently working on has an 8 inch head tube length. It would make it a lot easier for me if I could shorten it to about 5.4 inches. I don't see a measurement in your frame set up that allows you to change the head tube length. Did I miss something?
I know I've asked this question before, and I'm sure you told me how to fix it but I've forgotten.
I current project is building a 24 inch wheeled bike that has a five speed internal gear hub and a fairly upright riding style. If I can finish this bike chances are he may actually live longer. My current road bike which I designed a program called generic CAD is almost unmanageable. I just can't get my leg over the thing.( I get hit by a car shattered both my legs broke my back.)
You can email me at email@example.com Or give me a call at 971-212-1688 I live outside of Portland Oregon USA.
Thanks for the help Michael Frye owner Frye Bikes
