Beater Bar Parts

$1.50 - $65.00

Looking to join the meta with a 2wd or 4wd beater bar robot but don't know where to start? The Repeat Beater Bar system has been tested on top 3lb robots like Repeater, Knuckle Sandwich, and Unga Bunga. If you need a specific size weapon, you can still use the included hardware for your own custom bar and rest assured that the design has been tested at the highest level of competition. We realize that UHMW is not strong enough to support the kind of hits this weapon will deal out, so we're also selling anti-wallowing inserts inspired by those on Kamino! These are great for any type of vertical spinner; beater, disk, or drum alike. Can't choose how you want to drive your weapon? We have pulley options for both V-belts or inverted timing belts!
