I have the smallest ring on my Holy Trainer Nub, and it is too big. It slides almost all the way off. Is there a way to make it smaller so it fits better?
one solution could be heating up the ring in hot water and model the ring when the resin is soft. Not sure how it would end up.
I tried that method with the old device. It didn’t work too well. Thinking of cutting it at the bottom and using epoxy to rejoin the 2 pieces.
Holy Trainer makes a pull out device called the "Guardian" which is a small piece of plastic which fits over the tube and in essence "decreases" the diameter of the tube. The Guardian fits both the V2 and V3...and will fit the knockoffs too.
I cut a few mm out of the bottom of the ring, heated it up and pushed the edges together, then used epoxy to glue the cut edges and all round the cut. It works fine so far. It was only a Chinese device so only cost about £12 in the first place.
I’m the opposite, using 55m and it’s too small. Wanting to find a ring that fits but going to have to buy a new cage and what if that doesn’t fit? It’s not like I can nip into my nearest sex shop and get measured which is a shame
You could get a knockoff on aliexpress or amazon. They usually come with different ring sizes. I had some not so good experience with the manufacturing quality of these rings though. But for 20 bucks it is worth a try.
