Speed Bridge
The back of the TaylorMade M6 irons has a unique feature the company calls Speed Bridge. This vertical bar connects the topline to the mass at the sole of the club. It is designed to improve sound, feel, and ball speed. Connecting the Speed Bridge to the topline stabilizes that area of the club, preventing loss of energy at impact. That saved energy is transferred to the golf ball for more distance. Reducing vibrations also benefits the sound and feel of the club. Incorporating the Speed Bridge into the design also allows for the enhancement of the next feature, the new Speed Pocket.
