91MF, The cantilever rear debuted on the 3.0 frame, which appeared in 1989. With the steel fork it made sense to have a crit model with it's straight diameter downtube (stiffened the HT shell) and steeper head tube. The aluminum fork has a little less kick out which made a SR frame as nearly quick turning as the steel fork CR frame and the aluminum fork reportedly made a CR frame a bit twitchy at first, I can't say I noticed any difference. The CR was dropped around '92 because it simply wasn't needed.
BGirl, As far as I was aware the SR and the CR had the same BB height, the ST had a lower BB. There is also a CR300, which was sold as a frameset, this is what my '89 is. CR wheelbase is a bit shorter simply because of the steeper head tube, but the difference is slight. I wasn't aware that a BL could be had as a CR, but seems they could be... comparing the pics in post 1 and 17.
