Confirm before ordering

Measure the original selector pin

A calliper gives the most reliable measurement. Measure the metal shaft—not the handle, end cap or selector hole by eye.

  1. 01

    Remove the original pin

    Unload the machine and remove its existing selector pin.

  2. 02

    Measure the metal shaft

    Use a digital calliper across the widest part of the straight metal shaft.

  3. 03

    Choose the closest diameter

    A reading close to 8mm needs the 8mm GymPin; a reading close to 10mm needs the 10mm version.

  4. 04

    Check length and clearance

    Confirm the pin can seat fully and added plates will clear the stack, shrouds, cables and frame.

Never force a GymPin into the stack.If it does not insert smoothly, stop and re-check the diameter, alignment and usable pin length.

Common questions

Size guide FAQs

Can I choose by brand alone?

No. Brand guidance is a useful starting point, but manufacturers can change selector-pin dimensions between ranges and production years. Measure the original pin before ordering.

Should I choose 8mm if I am unsure?

No. Do not guess. Measure the original selector pin with a calliper or contact GymPin with the machine details.

What if my measurement is between 8mm and 10mm?

Check the calliper position and measure several points on the straight shaft. If the result remains unclear, send the measurement and photographs to GymPin before ordering.
