Gymnastics Bar Knob Screw Replacement: What Home Gym Owners Should Know

A single black ABS pull pin knob priced at USD 18.19 for home gym equipment such as stationary bikes and gymnastics bars. Here's what stands out and what to keep in mind before buying.

Last updated Aug 15, 2026

When a pull pin on your home gym equipment starts to feel worn or hard to turn, you need a replacement that works with the machines you already own. This guide focuses on one specific part: a replacement pull pin knob designed for fitness equipment like stationary bikes and gymnastics bars.

Quick verdict

This single black ABS pull pin knob is priced at USD 18.19. It is made for fitness equipment with a rotating pull pin, including exercise bikes and gymnastics bars. If you need just one replacement knob and the black finish works for your setup, this is a straightforward part to consider.

Who it suits

This replacement knob suits home gym owners who want a single pull pin made of ABS plastic. It works well if you are maintaining a stationary bike or gymnastics bar and would rather replace a worn knob than buy a whole new piece of equipment. It is categorized as an exercise machine attachment, so it is aimed at equipment that uses a ball-shaped rotating pull pin.

What stands out

The knob measures 6.5 x 4 x 4 cm, which keeps it compact for a pull-pin application. It is made from ABS and comes in black. The rotating ball shape is built for pull-pin action, matching use on exercise bikes and gymnastics bars. The package includes one pull pin knob, so you know exactly what you are getting.

Meaningful trade-offs

The main trade-off is quantity: the package includes only one knob. If you have multiple machines or more than one pull pin to replace, you will need additional units. The size is also on the smaller side, so it best suits compact knob areas rather than oversized handles. It comes in black, which is useful to know if you are trying to match other equipment.

Bottom line

For a single-knob replacement job on home gym equipment, this black ABS pull pin knob at USD 18.19 is a sensible candidate. It comes with one piece, has a clear size, and is built for the kind of rotating pull-pin mechanism found on stationary bikes and gymnastics bars. As long as the size fits your existing equipment, it is worth considering.
