Associated TC6.1 one way
Associated have released a TC6.1 and TC6 front oneway for high-grip conditions. Designed to ensure that both front wheels maintain maximum speed by letting the inside wheel turn slower than the outside wheel, which allows more consistency through a corner. As a plus, under deceleration, the front wheels are disconnected from the drivetrain, allowing their traction to be used solely for turning (and not driving), which gives more steering.
