Scroll down and read the FAQ on honing;

All true, but it doesn't say that properly honing the cylinder makes the rings spin around the piston.

However, I wonder how those "gapless" rings manage to form a good compression or oil seal. To work properly, a regular piston ring has to constantly exert a certain amount of tension against the cylinder wall. They are built slightly larger than the cylinder bore, and are "compressed" into the cylinder leaving a gap - so you can measure how much tension is left to hold it tight against the cylinder wall after it wears. If it is a solid ring, it will begin to leak and pass oil/gasses once it breaks in the cylinder wall and has even the slightest amount of clearance.

"Crosshatch angles can also vary depending on the application. These angles determine the critical ring rotation speed, generally a 45 degree crosshatch angle will do a very good job."

Gapless rings have an overlap, or are a double ring setup. They aren't "solid".
