I'm bringing up a really old topic, but its the only one I found with ring and pinion explanations. Since the new Calmini crawler gears are out, I have some questions.

If I were planning on getting a new R&P and the crawler gears, should I get the crawlers first in order to determine the new R&P ratio? Or would it matter, I have no idea. There is only 1 gear ratio on Calmini's gears correct?
