45.43 DragFactor Program Chip Upgrade (Pro and Lab CT ONLY)

Upgrade to version 45.43 Handlebar Controller to add Aerodynamic Drag Factor capability to existing PC-based Pro and Lab CompuTrainers.

Though a higher version number than the Puck version numbers, this is NOT a Cadence Puck or Nintendo-CompuTrainer compatible upgrade. Contact our sales department as noted in the Puck Upgrade section for Puck upgrade information.
