Portal

SKU: BBMGPL

Some balls are made to fill a specific spot in your bag. Portal was made to open up a new one.


Portal represents a different approach to a 900 Series ball, created for bowlers looking to see what is possible when a ball can clear the front of the lane and save its energy for what comes next. Its purpose is simple: get through the heads, retain energy, and create a sharp move down lane that gives you another option when you need it.


At the heart of Portal is the all-new Conduit AI Core. Its high RG and high differential are designed to help the ball ignore traffic in the heads and maintain its energy for the backend. Paired with the stronger RB 92 Solid cover, the core gets the traction it needs while the cover helps enhance its quick response time. The result is one of the sharpest backend reactions the Global brand has ever seen.

900 Global Portal bowling ball

Enter a world of
infinite possibilities.

The Portal represents a different approach to a 900 Series ball — engineered to travel clean, hold its energy, and make its strongest move last.

Portal Ball Guide

How the Portal fits your game.

01 What the ball does
Shape of motion

Skid-Flip

Skids easily through the front of the lane before making a sharp, high-energy move at the breakpoint.

When to use
  • When you need maximum motion downlane
  • When you need to create more entry angle
  • When earlier-reading balls lose energy before reaching the breakpoint
  • When you are opening your angles and need the ball to recover
  • When dependable friction is available downlane
Hook phase timing

Late

Reads the lane farther downlane, stores energy and makes its strongest move at the breakpoint.

When to use
  • When the front of the lane has started to transition
  • When other balls hook too early
  • When you need to preserve energy through the heads
  • When you are playing a deeper angle through the oil
  • When there is dependable friction downlane
Responsiveness to friction

Quick

Reads dry boards quickly and creates a visible change of direction when it encounters friction. The RB92 Solid cover provides traction while enhancing the quick response of the Conduit A.I. Core.

When to use
  • When you need the ball to recover from a deeper launch angle
  • When smoother shapes do not create enough backend motion
  • When you need a stronger change of direction at the breakpoint
  • When you need to create more angle through the pins
  • When the breakpoint provides consistent friction
02 When to throw this ball

Throw this ball when…

  • You need traction without an early hook phase
  • You need the ball to clear the front of the lane and retain energy
  • Your Early Traction Ball reads too soon
  • Your Strong Asymmetrical Solid uses too much energy before reaching the breakpoint
  • Your Benchmark does not create enough backend motion
  • You are moving inside and need the ball to recover downlane
  • You need a sharp backend response from a solid cover

Don't throw this ball if…

  • The lanes are too dry or burned
  • You need an early hook phase
  • You need a Smooth, Round or controlled Arc shape
  • You need to blend wet/dry rather than react quickly to friction
  • The breakpoint does not provide enough friction for the Portal to respond
  • Your current ball is already creating too much direction change
  • You need to keep your angles closed and minimize backend motion

Key use cases

  • When an Early Traction Ball begins reading too soon
  • When a Strong Asymmetrical Solid loses energy before reaching the breakpoint
  • When you need more traction than a Responsive Pearl
  • When a Benchmark does not create enough backend motion
  • When the fronts begin to transition but oil remains in the middle of the lane
  • When you need to open your angles and create more entry angle
  • When you want one of the sharpest backend motions in the Global line
03 Who is this ball good for?

Rev-Dominant

  • High RG helps the Portal clear the front and retain energy
  • RB92 Solid provides traction without creating the Portal’s strongest motion too early
  • The Late hook phase helps prevent the ball from using all its energy in the front of the lane
  • The Skid-Flip shape creates recovery when moving farther inside

Speed-Dominant

  • RB92 Solid provides the traction needed to read the lane
  • High differential supports a stronger change of direction downlane
  • The asymmetrical core creates a more forceful backend motion
  • Works best when there is oil through the front and friction at the breakpoint

Balanced

  • Provides a sharper alternative to a Benchmark
  • Combines solid-cover traction with a Late hook phase
  • Creates additional backend motion when Round or Arc shapes are not enough
  • Provides a clear Skid-Flip option within the arsenal

Power Player

  • High RG helps the ball retain energy through the front of the lane
  • High differential supports the Portal’s strong backend motion
  • The Late hook phase allows the ball to be projected through the oil
  • The Quick friction response helps the ball recover from deeper angles

Straighter Player

  • RB92 Solid provides traction for players using smaller launch angles
  • High differential helps create additional motion downlane
  • The Quick response produces a visible move when the ball encounters friction
  • Useful when a Benchmark does not create enough hook

Beginner

  • Provides a clear example of a Skid-Flip motion shape
  • RB92 Solid supplies traction on conditions where weaker balls skid too far
  • The Late hook phase helps the ball retain energy through the front
  • The Quick response makes the ball’s reaction to friction easy to identify
04 What does it pair well with?

Early Traction Ball

Why it pairs well

Reads the lane sooner and provides control on fresh or high-volume conditions. Move to the Portal when it begins hooking too soon or losing motion downlane.

Relationship

Earlier hook phase with less backend emphasis.

Benchmark

Why it pairs well

Provides a balanced, readable starting shape. Move to the Portal when the benchmark motion does not create enough traction or direction change downlane.

Relationship

More balanced, centered and predictable.

Responsive Pearl

Why it pairs well

Clean front-lane motion and aggressive backend torque with less solid-cover traction. Move to it when the Portal begins creating too much traction.

Relationship

Cleaner cover, similarly aggressive backend purpose.

Burn Ball

Why it pairs well

Controlled, low-flare motion when the Portal becomes too strong for the remaining lane condition.

Relationship

Lower hook potential, smoother continuation.

One of our sharpest backends

High RG preserves energy through the front of the lane. High differential helps unleash it downlane—creating one of the sharpest backend motions Global has ever produced.

RB92 Solid — Reserve 92 Blend
RB92™ Solid Cover

Traction that increases response

RB92 Solid provides the traction the Portal needs while Power Edge helps it stay clean through the front—allowing the core to respond quickly downlane.

Portal in your arsenal
Arsenal fit

Crafted for your arsenal

When strong solids use too much energy early—but cleaner options do not create enough traction—the Portal gives you another way to attack the lane.

Conduit A.I. Core rotating
Inside the ball

All new Conduit
A.I. Core

An asymmetrical shape built around a single idea: get down the lane clean, then change direction hard. High RG holds energy through the heads while high differential builds the flare that turns it loose at the breakpoint.
