Mizuno Introduces First Global Tour Ball


After 12-years of wind tunnel testing at the Mizuno Technics test facility in Yoro, Japan, the RB Tour and RB Tour X golf balls promise optimum greenside feel plus excellent performance in the wind. This is due to new drag-reducing technology – the Cone Profile Dimple (C Dimple).

“Mizuno has its own wind tunnel at the Mizuno Technics laboratory and a particular skill set in aerodynamics.  We’ve now built a reputation across Asia and Europe for producing a quality ball – working with tour winners, elite amateurs and emerging tour players.  The RB TOUR takes us to the next level and we’re excited to see where this takes us,” David Llewellyn, Director of R&D at Mizuno USA.

“We’ve been lobbied on every social media channel to introduce the ball to the US market, but we specifically wanted to wait for this ball.”


What enhances the speed?

The C-Dimple creates more trigger points to keep fast flowing air close to the ball’s surface for longer – simultaneously reducing drag, and strengthening trajectory.  During laboratory testing, a configuration of 360 Cone Dimples was discovered to be the most effective at producing a controllable, penetrating driver flight, and noticeable distance gains on full iron shots.

How were they constructed?

The RB Tour and RB Tour X’s high-energy four-piece construction blends 360 drag-reducing C-Dimples with: a high-traction Urethane cover for ultra-soft, responsive greenside performance; a high-energy Ionomer mantle layer; and a graduated hardness Butadiene Dual Core.

What are the differences in construction between the two balls?

The RB Tour model’s very soft compression offers lower driver spin to suit more downward angles of attack, while the RB Tour X is geared more towards mid driver spin for flat to upward attack angles.
