Shimano 2022 Bantam is back with 150 sized larger spool. One piece aluminum alloy body frame holds every component solid. Infinity Drive system has been employed for the first low profile bait caster among Shimano, to offer more dragging-less, more efficient cranking. In the system, pinion is held by one ball bearing at the gear top, and spool shaft inside holds it. SVS Infinity brake system controls spool speeds. Micro module gears offer very smooth gearing.
