989CLA (Custom Length Assembly) means lighter specification
head weight combined with new rear cavity twin weight bores to achieve normal swingweight/MOI assembly at custom lengths from 1 inch under to 1 inch over standard lengths (standard lengths based on 38” #5 iron with half-inch increments between each numbered iron)
Progressive blade height from semi-shallow in the #4, 5 to taller in the wedges keeps the CG lower in the low loft heads while raising the CG in the high loft irons to enable higher flight with the lower lofts and no ballooning flight with the high loft irons
Modern loft design to compare with other modern strong loft iron designs
Deep undercut back cavity design to increase MOI and off-center hit performance with low 2mm offset on each iron in the set
Outstanding sole design with beveled leading and trailing edge design, ideal for all types of grass and turf conditions
Available in RH in #4, 5, 6, 7, 8, 9, PW and AW, in bright mirror polish finish with silicon bead blast highlights and medallion cover for rear twin weight bores.
