btw, bago lang ako dito sa tsikot.. this forum is quite engaging, exciting, and interesting. more power!
Mas malaking bagay ang rpm at right gear siyempre -- that defines how heavy your foot is, after all. Pero may kinalaman din siguro ang gearing kahit papaano, lalo kung madalas ka naka-rekta. Theoretically, say, a car only has 3 gears -- mas hirap siya ma-optimize di ba? Kasi kung gitna lang ng bawa't gear ang optimal (halimbawa) -- adding more gears gives more 'optimal' points, making the car more efficient. Pero siyempre kung mabigat ang paa mo, wala din. OTH, kung mas konti ang gear, mas madalang mo kailangang mag-shift at mas malawak ang magiging band sa lower gears -- thus mas advantage sa arangkada (though less efficient nga).
