Fit and design are the real difference in any biomechanical device. Bikes are intended for use, not just art. The third step is the development of a full size frame blueprint. This step combines all of the information collected during steps one and two. During this phase, tube diameters and inside dimensions are chosen, frame geometry is developed and braze-on bits selected and positioned.
Tire size is taken into account and clearances noted.
This is the design and concept phase. If the concept is flawed, no matter how nicely made the frame, it can t be a perfect tool. This is, in many ways, the most difficult part of making one-off bikes. We believe this is part of the beauty of a custom bike though. There will never be another bike exactly like yours.
