Bike Anti-Porn - When Things Go Wrong

i dont understand your point? its a feature which is fucking strong, it features heavily on older bmx's when strength was an issue, strenght is also an issue on frames built for 700c wheels.

The point is that it was a silly-ugly-gimmick feature in the first place and is the reason why it was lost to history. I understand the charm of reinforced fancy overlapping wishbone junctions. The terrible one barcode and hoffman Taj frames probably demonstrate the "pinnacle".

But did you ever have a go one one of those BMX's ? they were heavy as fuck, making them pretty damn not-fun-at-all for street riding unless you were into gnarly drops. The care-free bunny-hoppin style of todays street bmx just would not work with those heavy bastard frames. With those tanks you just had to huck yourself off stuff. None of this bunny-hop 360 tailwhip malarkey.

Even on todays BMX bikes, the supposedly "weaker" simple seatstay junction is never the thing that fails. It is much mroe often the main tubes or where they attach to headtube.

700c bikes, particularly the forks and wheels are by their very nature much more fragile than a 20" wheeled BMX. The traditional seatstay setup is fine for BMX's, 26" jump bikes and steel MTB's. Why would it not be ok for a glorified hybrid?

For fixed riding in particular, the amount by which you are chucking yourself off stuff is very limited, and if you do your wheels and forks are much more likely to break.
