About Weight of Roller:
Lighter rollers weights require higher RPMs to push the rollers outward through centrifugal force and begin changing your CVT's gear ratio.
Heavier roller weights need lower RPMs to begin changing gear ratios.
Lighter roller weights = faster take-off acceleration, bigger strength, but lower top speed.
Heavier roller weights = slower take-off acceleration, higher top speed.
