AYLIFU M16 Pop Pull Pin Knob Adjustment Fitness Pop Pull Pin Knob for Fitness Equipment,64×36.2mm/2.52×1.42inch, Bicycle Equipment, Black 2PCS

These pull pin knobs for my exercise bike worked well and fit perfectly in size, good functionality, and sturdy materials.

Exactly the right size. Good product. All bad reviews are unwarranted.

Mine had some faded white paint

Somehow, these pins got lost from my granddaughter's gymnastic training bar while in storage. These pins are used to set the height of the bar so she can do somersaults over it, and its pretty useless without them. I figured out the thread size and pitch and searched all the local hardware stores for a replacement. I could not find anything locally and then searched Amazon. I was amazed to find exactly what I needed. The pins came Amazon fast and fit like a glove. Now my granddaughter can go back to practicing to be like Simone Biles and I am a hero for fixing it for her.

I wish I had known these existed long ago! Saved me from having to buy a new gymnastics bar. Fits perfectly!
