Srixon’s Rebound Frame which is in its second generation creates multiple areas in the head for the face and body to seamlessly flex to create better energy transfer to the ball resulting in more ball speed and more distance.
INCREASE FORGIVENESS
All three ZX MKII drivers performed exceptionally well on high toe misses during testing. Compared to center strike carry distance, impacting the high toe saw distance drop by only 7 yards. The high toe carry distance delta was near the top for all drivers tested and should be a welcome sight for golfers who routinely miss in this common location on the face.
LAUNCH OPTIONS
The ZX lineup has a driver for every player type. For golfers who want to launch it low, the ZX5 LS MKII provides a strong combination of low launch and spin characteristics. On the flip side, the ZX7 MKII is the higher launch option. In fact, the ZX7 launched an extra degree higher than the ZX5 LS during testing.
A standout in terms of overall dispersion (54 shots) during testing. Only one driver had a tighter pattern on the robot. It’s certainly one to try out if you’re seeking more accuracy.
Adjustability
The ZX5 offers the largest footprint with a lower profile and a flattened shape for boosted MOI. It comes with a single adjustable weight (8g stock) in the rear to help increase launch and stability and offer the most consistent distance around the face.
Low Spin
The standard ZX5 was just 100 RPMs above the LS model, so it would still be considered on the lower end of the spin rate spectrum.
The ZX7 MKII is the higher launch option. In fact, the ZX7 launched an extra degree higher than the ZX5 LS during testing.
Adjustability
It’s packed with adjustability, including two interchangeable weights for right and light ball flight bias, along with Srixon’s adjustable hosel, which offers a full 2° of loft adjustments (1° up and 1° down from standard).
Workability
The ZX7 offers the most compact shape and the most workability in the MKII line.
Only two other drivers we tested in this product cycle produced a lower spin rate than the ZX5 LS at 95 mph. Even more impressive was the spin rate in comparison to the previous ZX5 and ZX7. Compared to the ZX7, the ZX5 LS produced 250 RPMs less spin when averaging the spin rate across all nine face impact locations.
Adjustability
The ZX5 LS uses the same lower profile platform of the ZX5 but with an adjustable weight (8g stock) placed closer to the face. The ZX5 LS MKII Driver comes in lofts of 8.5°, 9.5° and 10.5°.
Low Launch
For golfers who want to launch it low, the ZX5 LS MKII provides a strong combination of low launch and spin characteristics.
The power in the ZX MKII woods comes from Srixon’s Rebound Frame which is in its second generation. This frame creates multiple areas in the head for the face and body to seamlessly flex to create better energy transfer to the ball resulting in more ball speed and more distance.
To put a number on it, Srixon says the newest generation offers a 10% larger Hi COR area on the face to help maintain maximum ball speeds over a larger area.
The flex zones of the ZX MKII woods work like double-stacked trampolines — The first area is the face, which features intricate variable thickness zones, including a 0.25mm thinner center point and 0.4mm thicker area at the perimeter than the last generation to impart more energy.
Behind the face is a secondary ring made of thin areas that deform during impact like springs on a trampoline. Once those springs rebound…you see where I’m going with this, more energy is effectively transferred to the ball.
To support the flexible rebound frame, the titanium crown utilizes a Star Frame construction that uses a series of ridges to support and strengthen it without adding extra weight. The saved discretionary mass is then used around the various driver models to produce ideal launch and spin characteristics.
