The new Magtronic rear unit was recently launched at Kartmania and received a resounding thumbs up from many of the visitors.
The new Magtronic rear unit still has all the functionality of it\'s predecessor but is now about half the size! Using strong, powerful magnets the unit can be mounted onto any axle size up to 50mm and can quickly show you the condition of your chassis/rear axle as it relates to twist, bend and crab.
