In longer clubs with low loft and a low degree of spin loft when the ball is hit, the clubface design element of bulge and roll helps to optimize ball flight on off-center hits.
What is Bulge and roll in golf clubs?
The curvature from heel to toe (horizontal) is called bulge, while top to bottom (vertical) curvature is called roll. Bulge compensates for the golf ball spin imparted by off-center hits. For instance, a shot hit off the club’s toe will have left sidespin; bulge makes the ball start farther right than a shot hit dead-center.
What is the difference between roll and bulge?
The curvature from heel to toe (horizontal) is called bulge, while top to bottom (vertical) curvature is called roll. Bulge compensates for the golf ball spin imparted by off-center hits.
What does bulge mean on a driver?
BULGEHORIZONTAL GEAR EFFECT. HORIZONTAL BULGE: The curvature of the face of a wood from heel to toe. Bulge aids in imparting corrective spin to shots hit on the toe or heel of the wood face. Bulge, which is responsible for horizontal gear-effect, is measured in inches, and the majority of drivers are built with 10 inches of bulge.
What happens to the ball at impact in golf?
EFFECTS AT IMPACT. The club head at impact will rotate around its vertical center of gravity (CG) axis, and not around the shaft’s axis. At impact, if the ball is aligned directly in-line with the club head’s CG, then no sideways twist will occur. However, golf is a game of misses.
What is bulge and roll on a driver?
The face of every driver (all clubs requiring a headcover for that matter) has roll and bulge while irons do not. Bulge is the curvature of the face from its heel to its toe, while roll is the curvature of the face from the crown to the sole.
What is bulge and roll?
What is bulge and roll? Bulge is the curvature of the clubface from the heel to the toe. Roll is the curvature of the face from the crown of the club to the sole. Both features have a huge influence on ball flight, due to the science behind gear effect.
Why are golf drivers not flat?
Driver Bulge A clubhead's horizontal curvature is known as its bulge, which is designed to partially counter the gear effect. If you hit the ball closer to a driver's toe, the face imparts sidespin that causes the ball to hook -- curving to your left, if you're right-handed.
Why do some golfers hover the club?

What causes toe shots?
The most common cause of hitting off the toe is releasing the club early, the wrists unhinging and the right arm straightening too soon on the downswing. Players who do that hit a lot of fat shots, so they learn to yank the club upward either by standing up or bending their left elbow.
What is the Centre of gravity of a golf ball?
What does center of gravity do for a golfer, and where is it located? On a driver, most golfers will benefit from a center of gravity that's low and back, meaning it's situated closer to the sole and back of the crown of the driver.
How often should you replace your golf driver?
3 to 5 yearsKeep in mind that 3 to 5 years of use is a general guideline and differs for all golfers. If you play 30 to 40 rounds per year then based on normal wear and tear you should consider getting a new driver every 5 years. If you play less than that, then you could wait for 5 to 7 years.
