How to Calculate When Changing Gears Rear Wheel Diameter Difference
Many of the biker modify the bike by replacing the wheels with a diameter smaller size. For example, a modified form of the chopper would not want to replace the wheels with a diameter smaller, so that the impression choppernya appear. Replacement size
rear wheel rim will affect the rear wheel, so that the necessary adjustments to the rear gear motors. Because if allowed to use the standard gear, TOP SPEED will be reduced.
How to Calculate When Changing Gears Rear Wheel diameter difference, let us learn together - together:
Rear gear adjustment formula:
D1/F1 = D2/F2
D1: total diameter wheels with standard tiresF1: Final gear ratio (gear rear / front gear)D2: total diameter wheels with tires modif (replacement)F2: the final gear ratio of conformityAll in a matter of milli meter .... (1inchi = 25.4 mm
Rear gear adjustment formula:
D1/F1 = D2/F2
D1: total diameter wheels with standard tires F1: Final gear ratio (gear rear / front gear) D2: total diameter wheels with tires modif (replacement) F2: Final gear ratio conformancesAll in a matter of milli meter .... (1inchi = 25.4 mm)For example, the rear wheel wears a size 18-inch alloy wheels replaced the wheels with a diameter of 17 inches. With a thickness of tire 90/90 and size 14 eye front gear and rear gear size 45, what is the replacement rear gear ...?????
F1= 45/14
= 3.2142
D1= Diameter of rim diameter + thickness of the upper tire diameter + thickness of the bottom of the tire= (18x25, 4) + (90% X90) + (90% X90)= 457.2 +81 +81
= 619.2 mm
D2= (17x25, 4) + (80% X90) + (80% X90)= 431.8 +72 +72
= 575.8 mm
Replacement tires use size 90/80 which means that the tire tread tires 90mm and height 80% of the tire tread is 72mmJust look for the F2 or size rear gear replacementF2= (F1xD2) / D1= (3.2142 x575, 8): 619.2= 2,988
The result is multiplied by the number of eyes front gear (gear still wear the standard 14)
2.988x14 = 41 844Then be accomplished to 42, now has met the rear gear to adjust the rear gear in sizes 42 eyes.
