"13 a 36 dientes" literally means "13 to 36 teeth" and I don't see why wrap capacity would be given as a range. There's no such thing as a minimum wrap capacity. I can't say for sure what it's referring to, but you find the similar stamping on Campy Rally and GTs except it's "13-36=36-54." They clearly have a higher wrap capacity, but I doubt it's 54, and it still leaves the 36 a mystery if it isn't what it appears to be. A ~45mm short cage is lucky to have ~25T of wrap. 36T wrap is more like what you could get from a ~75mm medium cage.
