No, those are just 77mm/80mm OD threaded metal rings screwed on step-up rings, it makes the setup sturdier, it is much easier to put filters on comparing to thin filmsy stepup rings, and they add some distance from follow focus to hood/mattebox. I found them by accident in those cheap Chinese collapsible rubber lens hoods, bought bunch of them and threw away the rubber part ;) and my setup is comparable in functionality to the part that proffesional cine-modding shops add on the lens, just for a fraction of the cost.
PS those Xume adapters seem cool, never seen that before
Highly recommended :) @inqb8tr - are those Xume adapters on your set of lenses?
That's the same guy.
Another option can be just get cheap 3D printer or go into place that have one and print your own.

These are the best solution I've found - pricier but fantastic. They look exactly the same as the gears posted by @inqb8tr
I have recently bought gears from helicoptersean from ebay, they are great. Here they are on my Nikkor DIY cine-mod set.
Has anyone tried the custom follow focus gears on ebay? They're only $45 from user helicoptersean. Curious to see how they work.
@Vitaliy_Kiselev where can I get this deal?
Btw we have CInematics gear now listed in 24h deal.
Question about ring gear material. I have the Fotga II FF unit and find the drive gear to be quite small in relation to my lenses (Canon FD's mostly L series). Due to this I seem to get a lot of slip and chatter especially if I try anything faster than a slow pull. The only lens gear I have that does not slip is one made of quite hard plastic where the teeth are very rigid.
Also, I prefer the gear belt that fits flush to the lens ring vs the standoff style, the standoffs just increase the gear ratio and potentially the chance of slip and chatter.
Can anyone give me a recommendation for gear belt style gears that are made of hard material? I already bought 2 more from the supplier where I got the one I have and they ended up being a new softer plastic that skips also. I like the idea of the zip-tie gears and would probably go with them if they are hard enough material to not slip. Thanks.
