Is anyone using these rims? are they tubeless compatable, have come on my bike with tubes. Do they need a stans kit? or just whip off the tyres and tubes, change the valves add some sealant and inflate them back up?

Run them without tyres

They’ll need sealing tape and valves such as a stans system but are designed to work well tubeless so should be easy to convert.

Nice rims, surprised more people don’t run them actually.
