SLINGSHOT FRAME (OLD SCHOOL BMX TECHNOLOGY)

Here’s an interesting piece right here. I’m not really into that crazy design but i’m pretty curious how a frame like this will respond to aggresive riding. Maybe it was good for montain bike but i doubt that kind of suspension will improve performance in bmx riding, in fact suspended bike never make it into bmx activities and there is probably reason for that : rigidity is an important factor in rapid movements. Anyway those frame were now part of the history and must be part of the Bmx Museum right now. Just curious and interesting thing! -KoolFunc’88

“Slingshot bikes use a unique mid-frame suspension system.  The conventional down tube is replaced with a steel cable suspended from a spring.  There is a hinge on the top tube right in front of the seat tube.  The idea is to use the spring and cable system to return the energy lost during the pedal stroke.  All of the energy is returned since there are no frictional or damping losses in the spring system.   Most bike designers seem to radically change bike designs every 3-5 years.  Slingshot has managed to utilize a single design, with many detail changes, for about 20 years now.  I think that makes them fairly unique within the bike community.” (Greendale Bicycles testimonial)

One more time thanks BmxMuseum for the restorated bikes picts.
