Interchangeable Pulley Ratio Modes

Interchangeable Pulley Ratio Modes
Switch between precision control and all-out strength
The B17 features an interchangeable pulley ratio system that allows effortless switching between 1:1 and 2:1 resistance during workouts. In actual use, the transition is remarkably simple — pulling one cable engages the 2:1 ratio, offering lighter resistance, smoother control, and longer cable travel, while pulling two cables simultaneously activates the 1:1 ratio for direct, heavier resistance. This intuitive setup enables quick transitions between training styles without any mechanical adjustments, helping users maintain rhythm and focus throughout their workout.
Enhanced Weight Stack System
Built-in design with smart expandable loading
Enhanced Weight Stack System
Built-in design with smart expandable loading
The B17 is equipped with a newly developed built-in weight stack system that supports both lighter loading options and heavier strength challenges.
Each side provides 130 lbs of selectable weight stack resistance and can be expanded by adding an additional 130 lbs of weight plates through the external selector rod located on the weight stack header.
The selector rod is detachable, allowing for precise 5 lb incremental adjustments within the upgraded weight system.
The entire system is enclosed with protective weight stack shrouds, while a shock-absorbing rubber pad is positioned at the top to reduce noise and prevent cable impact at the upper limit of motion—ensuring a safer and quieter training experience for every user.
Upgraded Adjustable Leg Holder Premium with Added Versatility
Enhanced support and multifunctional design for stability and comfort.

The roller section (each roller measuring 9.8″ in length and 4.7″ in diameter) can be detached and replaced with the foot plate, allowing users to perform seated rows on a weight bench with stable body positioning and improved control.
Upgraded Knurled Handles for Refined Control

Both the Smith bar and hook plates are chrome-plated, providing superior durability and protection against wear and paint chipping. Built for heavy performance, the system has been drop-tested for up to 400 lbs to ensure reliable safety during every session. When not in use, the built-in top storage hook keeps the bar neatly secured and out of the way for an unobstructed training area.

Larger rollers ensure ultra-smooth and stable sliding without wobbling, while the knurled handle provides better grip and leverage for effortless repositioning. A new tension adjustment design lets users fine-tune and adjust how tightly the trolley moves along the upright, and a rubber pad at the base prevents impact when lowering the trolley to the bottom.

Frequently Asked Questions

What is included in the B17 package?

Please check our B17 product list.

What are the main highlights of the B17?

The B17 introduces a series of light commercial upgrades designed to deliver premium performance, enhanced user experience, and greater versatility. It features an interchangeable 1:1 & 2:1 pulley ratio system, a newly developed built-in weight stack system that supports both lighter and heavier loading options, and integrated practical attachments such as the Leg Holder Premium, long-range high pulley, and telescoping foot plate. It also includes a comprehensive storage system for a cleaner and more organized training setup. For detailed specifications and features, please refer to the B17 Product Features section.

How is the B17 packaged?

Unlike our previous Smith machine or power rack models, the B17 is shipped in a single reinforced wooden crate for enhanced protection. This upgraded packaging method ensures all components stay securely organized and well-protected during transportation, reducing the risk of damage and making the unboxing process more straightforward.

Package dimensions: 85.04 X 27.56 X 20.47"(WxDxH)

Package weight: 998.69 LBS

What training systems are integrated into the B17?

The B17 combines five major training systems — a power rack, Smith machine, dual cable pulley system, multi-grip pull-up bar, and a 360° landmine.

While the core setup remains the same, the B17 introduces upgraded attachments and refined craftsmanship that further enhance the functionality, comfort, and overall training experience of these five systems.

What is the cable pulley ratio of the B17?

The B17 features an interchangeable pulley system with both 1:1 and 2:1 cable ratios.

Users can pull one cable to engage the 2:1 ratio for lighter resistance and longer cable travel, or pull two cables simultaneously to activate the 1:1 ratio for direct heavier resistance. This intuitive design allows users to adjust training intensity seamlessly without mechanical changes mid-workout.

Can the B17 be customized with different attachments?

Yes. The B17 is compatible with a wide range of Major Fitness attachments and accessories, allowing users to expand their training setup as needed.

It already comes equipped with our latest heritage series J-Hooks, reinforced spotter arms, leg holder premium, high pulley system, upgraded cable handles, telescoping foot plate and dip bars, while also being compatible with our current machine accessories, such as the rack-mounted leg extension and multifunctional handle bar.

This versatile design gives users flexibility to personalize their setup and get the most out of their B17 for different training goals.

Does the B17 come with four handles, including the lat pulldown bar, nylon stirrup handles, straight bar, and T-bar?

The B17 includes three upgraded cable handles — a lat pulldown bar, straight bar, and stirrup handles.

All three have been refined for improved comfort and control: the stirrup handles now feature aluminum grips, while the lat pulldown bar and straight bar are upgraded with built-in bearings and knurled grips for enhanced ergonomics and a smoother training experience.
