I could have sworn that the word on the street of yesteryear was that SLX was for lighter riders, SL the standard, and SP for the big guys.
Anyway, the helical internal ribs on the SLX were designed for what end again?
I think it was for light riders because the really thin tubing might not hold up to a bigger/heavier rider. I don't know if that's the case.
