Years ago I bought a mountain (style) Raleigh for $5 at a thrift shop. The bike was in great condition. Only later did I learn that the whole frame was glued together, and had been recalled. It seems that some people had the idea that this bike was an actual mountain bike, and the frame would collapse if it was used as such. I had that bike 15 years, and one night I left it downtown, unlocked, and forgot about it. When I went to retrieve it, it was gone. Which hurt, because the tires were new. But the frame never failed in more than a decade of normal use.

I had that same bike for several years, and it gave me no problems. But a friend had one onto which he mounted a Bellingham designed and manufactured suspension system. This thing was a spring like device about 12" or so long with a shallow S curve. One end was fastened to the forward part of the top tube and extended rearward back over the seat tube. Attaching your seat to it turned it into a springy cantilever that gave you a softened ride. If you can picture this (I realize my description is sort of lame) you can imagine it put some pretty serious forces on the top tube. Eventually, his top tube broke, ruining the frame. Though Raleigh promised a life time guarantee on their frame, I'm sure they would have rejected any warranty claim because it wasn't designed to withstand such stresses. That was a glued frame (alloy tubes glued into alloy ferrules or sockets; or perhaps the tubes were composite, such as carbon fiber.. Raleigh promoted it as a high tech solution, calling "Technium" I believe. There is an article about the Technium system on line, but I was not able to open it.
