Hmmm.
I think you are still talking about tweaks rather than real innovation.
What I do think would be a major step forward is the development of custom carbon frames at a price point that allowed people to walk in and order one, and see it built in a reasonable time.
The idea that building a steel frame with a few changes to geometry and tube length or swoopiness qualifies it as some how better than a mass produced frame is hard to justify.
I suspect that you could take a steel custom frame from the UKs best builder and get it reproduced in China or Taiwan, in quantity, with good quality control, in half the time, for half the cost.
Maybe I have a different attitude towards bikes than others; I see them as tools rather than objects of beauty, as functional rather than aesthetic, although one does not exclude the other.
