For any Ti lovers, I envisage the following process:

1. I get my frame, fork seatpost etc etc, build the bike up.
2. I go for rides. Many rides.
3. I tear myself away and write a review of the bike, plus any recommendations for improvement.
4. We liaise with Peter Reich about how to proceed, since the design belongs to him. Peter gave me permission to get one successful frame built, but not to go into a business arrangement.

My design tweaks:

* I made the twin top tube design change because the builder did not have a large enough oval tube. I did some engineering calcs on the tube torsional stiffness and tried to get something close to the aluminium version's stiffness.

* I designed an easier-to-produce pivot for the fold, and a way to make a pivot on the dual tube system.

* I made a small change to the geometry to accommodate a slightly shorter fork.

* I made the top tube 25mm longer for a slightly taller average rider.

* I omitted the brake pivots. I will use this one with road brakes.

* I added cable stops, cable tie points and a cable pulley boss at the bottom rear of the seat tube for easier derailleur cable installations.

I don't regard any of these as radical enough to justify calling it anything else but a true blue Swift.
