I just got some YYF response pads in, but they do not fit my PGM2. The outside diameter is too small. The ones I got were the 21mm OD. Is there a bigger size? I did not see any in the YYE storefront. ---

Are you sure it doesn’t fit? It’s the correct size… Can you stretch it fit it in? Sometimes pads fit snugly. ---

They fit in the groove, but there is a gap between the outside of the pad and the outside of the groove. The pad does not fill the groove all the way. ---

It’s supposed to leave a little gap. ---

I measured them and they are the wrong ones. They are the 19mm, just in a 21mm package. ---

Why don’t you upload a picture of it and let us judge whether it’s the right size or not? If you’re just gonna ignore everything we said then why bother asking? ---

Yoyofactory has shipped thousands of pads… maybe there was a package misprint… ---

They take k-pads. Flowable silicone is your best option. Any size: you can always fill it with flowable silicone ---

Thanks for all your help, guys. After I measured them I got a hold of YYE, where I got them, so I’m getting a new set.
