i have been looking at specs of the bikes, i was right in what i remembered as being the specs
552 was 7 speed lx
752 was 7 speed dx
952 was 7 speed xt
all came with flexstems, and the 752 and 952 had the option of rockshox mag 20 forks, and as has been said the 952 was a Ti flexstem.
i bought my 552 as a frame only, then added mag 20's then built it with m900 xtr
currently my plan is to leave the front rigid, but get a flexstem, then strip either my alpinestars cromega or my orange aluminium elite, this will be temporary as i like both those bikes as they are, but this way i can see how it rides before i decide to go buy all the parts!! (me being sensible?)
anyway here are some pics i have found of each model, including one where a guy has made the frame into a tv stand! (and he's not using the brake rocker so i have emailed him!!)
You have enemies? Good. That means you've stood up for something in your life.
