Here's what DeeEight over at MTBR has to say:
Aegis and kestrel were spin-offs of a company in the USA which made composite frames for other brands (including Trek - before they moved production inhouse) which included Bik in france.
The engineers / designers had a falling out over what was better...
Doing 1-piece monocoques which required entirely different molds and jigs for each frame type and size (those that founded Kestrel favoured this method) which is more expensive but yeilds a better product for the individual customers and which is how the Bik frames were made.
OR
Doing multi-piece construction with common subsections joined at lugs, so you can share sections between frame sizes, which is cheaper and compromises a perfect fit for a customer (which is what the Aegis boys wanted).
