The TSR1 driver is built for ultra-lightweight speed and distance and provides players the launch characteristics and speed to deliver effortless added yards to every drive.As a maximum performance 460cc driver, TSR1 is roughly 40 grams lighter than TSR2, with weight savings coming from a lighter headweight, 40-gram shaft and lightweight grip. The elimination of excess weight, combined with improved aerodynamics and a similar �boat tail� shape to TSR2, helps golfers swing TSR1 faster through the air. Multi-Plateau Variable Face Thickness technology found in other TSR driver models assists in speed retention from off-center hits, while a deep CG almost perfectly centered to the face promotes higher launch and exceptional ball speed.
