Found this outside my climbing gym. Spinergys, carbon frame with aluminum lugs (one lug had "Alan" on it), carbon flat handlebars with no tape or grips, but a chrome fork???

I should have left a note just in case he/she doesn't know of the danger he may be in.

Specialized Epic? I saw one at a pawn shop not long ago, was tempted to buy it despite it being the death trap that 20 year old carbon tends to be.

That's an early carbon fiber bike, before they learned how to make monocoque (single complete mold). So, instead they would lug straight carbon tubes together with aluminum lugs.

With pretty poor quality glues for the most part. Its really hard to glue two different matterials together, not to mention metal glues are tricky.

I've seen a few to many of those frames 'repaired' with epoxy. They look great, but I'm always a little scared; you never know how the previous owner treated it.

Yeah, if I ever bought one I'd be way too scared to ride it anywhere, it'd be more like wall art than an actual bike.

I mean, if the frame doesnt self destruct and wheels don't explode whoever the owner is will probably ball tap himself at least once on that bike.

I hope the owner has accident insurance.

I've heard a lot of bad things about ALAN's, which started off as early attempts at reaaaally lightweight aluminum anodized frames. My buddy has an old ALAN conversion and while I don't necessarily trust the lugs on it, it rides like a bullet and I can't help but think that they might not be all that bad.

lol im almost done with my "death trap" bonded lugs vitus 979 build...
although thats aluminum into aluminum and not two different materials. its not so much the glue that holds it together but stuffing a tube into a slightly smaller hole in the lug with use of heat...i think. theres been reports of them failing or whatever but most of it is just the same story being rehashed over and over. failures are typically not catastrophic and are forecasted well in advance with obvious "oh **** that dosn't sound good" sounds. or so ive heard of the vitus 979s.....not as sure with alans. especially the carbon into aluminum alans. they sure look purty though.

ill let you guys know if i die once i start riding it lol

I rode a lugged carbon road bike once. It squeaked and creaked a lot.

The Alans were "screwed and glued", so they never failed catastrophically. They could get a bit loose, but they wouldn't fall apart. I had one in the late 1970s, and it was a comfortable soft ride but a totally flexible wet noodle that would ghost shift every time I stood up on it.

I owned a Vitus 979 back in the late 1980s. It was light (for the time period) but rode like a creaky wet noodle compared to the lugged steel Trek I also had at the time. Didn't keep it for long.

more or less dangerous than a piece of crap conversion with no brakes?

the all-alloy bonded bikes were much more solid than the alloy-lugged carbon bikes...alan and vitus were pretty much the the only players, though they were rebranded a bunch (guerciotti, tomasso, others i'm sure).

big difference was the adhesive. the alloy bikes could be oven-cured at higher temps, so they used different glue. the carbon ones used a lower temp (and less strong) version, and were notorious for failing after being left in a hot car (for real).

i had a vitus carbone 7 for a while. light, cool, flexy, and ultimately too big for me. in small sizes with low-power/light riders, they were great bikes. my 5'0" / 95lb girlfriend had one, and it was like 17lbs in the late 80s (built with superbe pro and gel 280s)! but in real man-sizes, the small diameter alloy tubes were ridiculously soft. (though the hard-man sprinter sean kelly rode vitus for years).

the early specialized bonded carbon bikes were much more solid in my experience. i had a 2nd gen version with slightly oversized tubes (still bonded) that was a fantastic ride.

who cares spinergy's are so boss, i want a front quite badly at the moment. bring it on i ain't even scurred

I have an old specialized epic. Lugged carbon. Rides pretty nice as far as I can tell. Hasnt blown up on me yet, have had it for 2 years now.
