Guys, share ko lng. Kung gusto nyo magcompute ng expected speed gain from changing you front and/or rear sprockets, try nyo tong site na to. Ang mga variables na kailangan ay ang inyong stock sprocket combi, ang top speed nyo sa stock sprocket combi, at sa kung anong RPM nyo naabot ang top speed na to, plus ang gusto nyong ipalit na sprocket combination.
Since kailangan nyo ng RPM reading, dapat may tach kayo (my wave100 tops out at around 10500-11000 rpm). Kung wala kayo tach, cguro d2 nyo na lng i-pattern.
Yung tool nga pala mismo, medyo may topak ata ung html code nya, pag enter mo ng value. kala mo wala, pero black lng kasi ang font (black background) kaya di mo kita. I-highlight mo na lng. So far I have tried two sprocket combi's, 14-34 and 15-35, and based sa gearing calculator, accurate naman yung readings.
HTH guys.
