I recently posted to inquire as to whether or not my bike was the right or ideal size. My question was.....I have a 2004 Specialized FSR XC Pro and I was told my a bike shop that it is a medium and too big for me.

Here's the part that I didn't notice....There is a sticker on the frame that I think is the size....It says Specialized on top....on the bottom it says "Innovate or Die" and in the middle it has an "S". I thought the S was for Specialized but now I think it is the size....

The weird part.....I measured from the middle of the bottom bracket tot he top of the seat tube collar and it is def either 17 or 17.5 inches which would be a medium by any brand. I really can't figure out if the bike was mislabeled, if Specialized changed their sizing or what. Or maybe that "S" really is just for specialized.

Any thoughts?
