Product Information
The Original 2" GymPin is designed for lifters who want to add more resistance to compatible selectorised cable machines once the standard weight stack is no longer enough.
Instead of being limited by the built-in stack, the GymPin allows you to load 2" Olympic weight plates directly onto the machine, giving you a simple way to increase resistance and continue progressing.
Designed and precision-manufactured in the UK, The Original GymPin is available with either an 8 mm or 10 mm small-end diameter, allowing you to match it to your machine’s existing selector pin size.
Simply check your machine’s pin diameter, insert the GymPin into the weight stack, load Olympic plates onto the large end, and train with added resistance.
The Original GymPin is built for lifters who have outgrown the standard weight stack on their cable machine and want a practical way to keep progressing.
It is suitable for serious home gym users, personal training studios, strength facilities and commercial gyms where compatible selectorised machines are used.
It is especially useful for exercises where progression can quickly be limited by the machine’s built-in stack, including pulldowns, rows, cable presses, cable curls, triceps work and other heavy cable-based movements.
Available in 8 mm and 10 mm options, The Original GymPin gives users the flexibility to choose the version that best matches their machine.
The Original GymPin was created to solve a simple but frustrating problem: many cable machines run out of usable resistance before the lifter runs out of strength.
For serious training, progression matters. Once the weight stack is maxed out, you either compromise the exercise or find a way to add more load. The GymPin gives you a cleaner, stronger and more practical option.
It was designed to allow 2" Olympic plates to be added directly to compatible selectorised machines, helping lifters keep pushing beyond the standard stack.
Made in the UK and built for repeated gym use, The Original GymPin reflects the core GymPin idea: simple equipment, serious loading, no unnecessary theatre.
The Original 2" GymPin is designed for compatible selectorised cable machines and allows 2" Olympic weight plates to be loaded onto the large end.
The large end measures 155 mm long × 49.5 mm diameter, making it suitable for standard Olympic plates with a 2" centre hole.
The small end measures 102 mm long and is available in either 8 mm or 10 mm diameters. You should measure your existing selector pin or weight stack hole before ordering to ensure the correct fit.
Available options include a single GymPin, a pair, or a mixed pair with one 8 mm and one 10 mm version.
Product weights are approximately 864 g for the 8 mm version and 897 g for the 10 mm version.
Always check compatibility before using The Original GymPin. Measure your machine’s existing stack pin diameter and confirm that the selected GymPin size is suitable for your machine.
Always confirm with the gym owner, facility manager or equipment manufacturer before using the GymPin on any machine that is not your own.
Do not overload the machine beyond its intended capacity. The GymPin adds external load to the weight stack, but the machine’s frame, cables, pulleys and guide rods still have their own limits.
Load plates evenly and securely. Check that the GymPin is fully inserted before use and that the added plates have enough clearance throughout the full range of movement.
Use controlled form, inspect equipment regularly, and stop immediately if anything feels unstable, obstructed or unsafe.
