    I got some 16mm clutch rollers for my winder and would like to know how they will affect the shift vs stock rollers ?

    Thanks

    Lower engagement, lower shift force, lower RPM throughout the shift range.

    Doesn’t lower rpm mean it’s loading the motor more ?

    I disagree..... larger rollers will raise engagement, lower belt squeeze, and raise rpm the first 2/3rds of the shift range.
