I used powder-coaters masking tape to ghetto tubeless my Archetype rims and it worked perfectly. Lot cheaper than stuff sold as tubeless tape. There's at least one big manufacturer that uses this stuff out of the factory for tubeless, can't remember which one it was though.
Anyone used the black Tesa instead of the yellow tape? Seller says it's better but they would.

There's no 28mm Tesa tape. Am I going to have to do two side by side wraps of 25mm? Or is there a 28mm tape I can use?
