Spine Alignment - More accuracy and distance
All golf shafts have a spine which is stiffer than the rest of the shaft. Spine Alignement means that we will find the spine of the shaft and assemble it to face the target. This means you'll get more accuracy and distance because the shaft will bend straight back.
By assembling the club with the shaft in its most favorable orientation, with the spine facing the target, off-line bending and twisting of the shaft is minimized and impact repeatability on the center of the clubface by the golfer improves up to 51%.
Normally when we assemble golf clubs we align the shaft so that the logo/text is pointing forward. But because the manufacturer does not spine align the shafts before they paint the logo/text, this text can be turned the other way when we do spine align.
