I have noticed you have made multiple prototypes (titanium bikes in this case), and I understand you are iterating to improve the overall design, but my question is what is the lifecycle of a prototype like for a framebuilder? For example, how long do you use a prototype before moving on to another and what happens with older prototypes as you move on to better designs (i.e. do you cut them up to see the efficacy of your welds (in this case) and to see if anything was stressed more than other parts or do they become part of the shop decor as pieces of history)? As always, the frames look amazing.
