Okay, Im looking at the Stolen Five-O, it says (the description in the magazine) Integrated headtube has dual gussets for strength. Wishbone chainstay, 14mm dropouts 3/16" thinck, seatstay U-brake mounts, cable guides 13.75"
Sizes are 20.5 and 20.75 (Euro BB)

So my question is, how do I know what i can do with that?
