I ve been thinking of buying a speedster and checking out 2012 models. One thing I am curious about is : is the frame of an s10 and s50 the same? scott uses the same frame all in scale alu models so maybe same approach might be taken in speedsters too?

thanks ... 50-24-s52/ ... 0-20-xl58/

edit: after a second look I think S10 & S20 are different than the rest
