Product Summary: Acer SR1 Forged Titanium Driver, Golf Club Heads Only, No Shaft

From Acer
Active Cup-Face Construction: Pushes the weld back away from the actual face allowing more deflection to occur. This produces higher ball speeds to areas over a much wider area than the center of the face as compared to traditional edge-welded designs.
Gravity Port: A rear center of gravity location produces a high launch angle, provides greater forgiveness on off-center shots, and makes it easier to close the club face at impact
4-Piece Forged: Equipped with a 6-4 Ti face, this high quality driver head is finished with a black PVD finish for aesthetics and durability
Golf Club Driver Head Only: Intended for custom assembly with your preferred .335” diameter shaft, grip and length
Specifications and Warranty: Designed with 12 degree loft for right-handed golfers, 202 gram head weight, 58 degree lie, 460cc volume, 54mm face height, 1 degree closed face angle and backed by a one-year manufacturer’s warranty
