Well ring size isn't nothing to do with the testicles pulling out.slave d wrote: ↑Sun Feb 05, 2023 5:49 pm Have to say that the ring size has absolutely nothing to do with testicles pulling out. It is totally a gap issue, the gap between the ring and the cage. If you think about it the testicle doesn’t pull through the ring at all !! it pulls past the gap between the ring and the cage. Ring size only controls the security of the whole device and even with the loosest ring testicles cannot pull through if the gap is right. For some reason many people don’t seem to get this but look at the device and you’ll see I’m correct !!
You're talking about the "horizontal" ball gap.
What the ring size does change is the "functional" ball gap or if looking at a design from the side, the diagonal distance from the cage to the ring (it gets more complicated in 3D space as the testicles are offset from that mid point).
The functional ball gap is going to come down to ring size, ring shape, horizontal gap, cage outer diameter, and cage shape.
Most people experience the testicles pulling out because they need a base ring size that is larger than the tube, by more than the size of their testicles. IE the functional ball gap becomes close to / larger than the testicles, allowing them to squeeze through.
Reducing the horizontal ball gap like you're suggesting is reducing the functional ball gap. But like you said yourself, if not done right it can introduce other issues by "pinching/crimping" the scrotum in certain areas.
For my Evo, I actually don't touch the horizontal ball gap very often as I control for the functional gap in a more reliable way.
Both my base ring and cage scale together to maintain a roughly 5-10mm functional ball gap depending on the customized ring shape.
Its just that off the shelf cages allow for mismatches in base ring to cage sizes which then needs to be controlled for using the horizontal ball gap. It's literally behind the principle of the CB-X cages where you go with the smallest ring size that is comfortable, and then reduce the spacers to the shortest possible.
