They were very comfortable and snaps back at you when you are off the saddle, but for a big rider, they were a flex-o-rama type frame. They were a lot stiffer then the Vitus I was told by people who had both. I beat the heck out of that look frame for a few years, and it held up very well with the exception of a slight surface paint cracks on the head tube lugs. It even survived a few major crashes on our training rides. Thankfully I did too. On those Vitus frames, about 50% of the people I talked to has issues with it, and many of them have no issues at all. IMO, I think it depends how hard you ride it. How much do you slow down or stay off the saddle when you hit that giant pot hole? Getting out of the saddle, flexing that poor frame every time coming out of a turn will shorten the lift span on that epoxy I suppose.

The ALAN tubes were screwed and glued into the lugs. I don't hear much about them coming loose. The Vitus tubes were pressed and glued. Some were pinned,
AFAIK that wasn't a factory thing, but a modification. When you buy a Vitus 979 or 992, or any bonded tube frame, avoid the ones with corrosion at the junction.
