McDermott i-1 Big Boy Break/Jump Shaft Black Collar 3/8"-10 13.25 mm tip

The McDermott i-1 Big Boy High-Performance Break/Jump Shaft is the most powerful shaft in McDermott’s i-Shaft series, engineered specifically for explosive break shots and controlled jump shots. Its wider 13.25 mm diameter, specialized short break/jump taper, and Triple-Layer Carbon Fiber core are designed to deliver high energy transfer while maintaining excellent cueball control.

This shaft is made specifically for McDermott cues with a 3/8"-10 joint and features a black collar.

Important: This shaft will not fit cues that use a joint other than 3/8"-10. Please confirm your cue’s joint type before ordering.

At the tip, the i-1 Big Boy uses a Navigator Break Impact hybrid phenolic tip. Unlike conventional phenolic break tips that emphasize power at the expense of control, the hybrid construction is designed to provide strong impact performance together with improved cueball control, making it well suited for both breaking and jumping.

McDermott’s patented Tenon Tip Technology transfers energy from the tip directly into the carbon fiber core. This design increases the effective sweet spot of the shaft and produces a more solid hit, helping maximize shot accuracy while improving the efficiency of energy transfer during powerful break and jump shots.

The Triple-Layer Carbon Fiber construction runs through the i-Shaft design to improve radial consistency and reduce the natural inconsistencies associated with traditional all-maple shafts. Combined with the Big Boy’s larger cue tip diameter and dedicated break/jump taper, this creates a firm, powerful hit with the stability needed for aggressive shots.

Radial consistency is the shaft’s ability to perform the same way on every shot regardless of how the shaft is rotated. The i-Shaft’s Triple-Layer Carbon Fiber Core is designed to provide more consistent performance around the full circumference of the shaft, helping produce a straighter cueball path and minimizing the amount of compensation required for spin and throw.

McDermott cues and performance shafts are among the most recognized products in the billiard industry. Manufactured in Menomonee Falls, Wisconsin, McDermott products are known for quality construction, premium materials, detailed craftsmanship, and extensive customization options.

Proudly made in the USA, McDermott cues are backed by the company’s lifetime warranty, including warpage, and lifetime maintenance program, subject to McDermott’s warranty terms and conditions.
