SL: Super Light (saw that somewhere but I'm not sure) SLT: This is their Super light top component bike with no costs spaired. TM: Trans Mountain RACE: No Idea,even though I have one. Someone told me once that the Race is a little longer than the standard bikes, so better for speed. Not sure there. Action Team: Is their Racing machine with top components, but built for punnishment not lightness like the SLT
I am not sure if all the above is true. Maybe someone can add more / Correct my remarks
