The first production all carbon bike that this company produced was the Trek 5000, yes made for and sold by Trek - we've got one here in the office...it's in pristine shape - a really piece. That was in 1986. After that, the company, then called Graftek started making frames for other European companies like Basso. Got a couple of those too...pretty cool bikes. In 1993, the AEGIS brand was born, and the evolution of these first road bikes became known as simply the "AEGIS", which eventually changed into the Aro Svelte. This design has remained relatively unchanged since then - other than different carbon layups and bonding techniques. Some early models had problems with bottom brackets that would spin after several years - so we fixed that and covered it with our lifetime warranty. That was a common issue with most early carbon bikes.
What I mostly see is people sending back their 5 or 10 year old frames to have them refinished and repainted - yes these bikes really do last this long. People constantly tell me how good the ride is, and when they get back their 10 year old repainted AEGIS, they say it feels like they have a new bike. We really don't build carbon bikes with a primary emphasis on weight, or the lack thereof. We build them to be smooth, compliant and super stiff, as well as durable and dependable. There's a guy in my home town, he's 73 years old, he's got over 50K miles on his Aro Svelte - he's ridden it across the country twice - never had any issues with it. I've personally raced my Aro for several years and while I'm no elite rider or stage winner, my bike has faithfully gotten me to the line every time.
As I said before, everyone makes a carbon bike now - well, in truth everyone designs a carbon bike now, to be made by someone else. The majority of these bikes are designed to be superlight, which means they are built with less and less carbon. Take away material and you take away the individual fibers that are so good at absorbing road shock and transferring rider energy. This is where our bikes are different, and why we feel they are better. I guess time will tell if some of the other carbon bikes out there now will still be ridden and loved when they are 10 years old.
