The question has been raised about the originality of the Frogs.
All I can tell you is that I bought these back in 1992 from a shop in Sheffield called Langsett Cycles, so Im fairly certain they are genuine.
I notice that the new release ones have a plastic hinge, but I cant find any good pictures of the originals, all I know is that back then, I paid about £60 for them (I think) I also bought some Mumbo's to race in.
If anyone can confirm the original design, Id really appreciate it.
