AVID have introduced new Triad direct drive for the Team Associated B6.1/D and the Yokomo YZ-2 and carbon fibre parts for the B6.1/D, T6.1, and SC6.1. First up is the Triad direct drive allowing stock racers to remove the entire clutch assembly for conditions where the driver feels having less rotating mass and zero slip except from the differential is beneficial.This system is the lightest direct drive unit available today for the B6.1 coming in at 8.6g (72t), just beating out the AE direct drive at 8.8g (72t). But with the AVID Triad direct drive you get to run the full-width topshaft gear (no more stripped idler gears), you don’t have to change out the topshaft, and no screws you have to worry about falling out. AVID accomplished this by replacing the 6.4g of steel weight from the long screw and spring with a minimalist design done in aluminum. There is also an included M3 aluminum flanged locknut to remove even more weight if you are using the stock steel nut.
