Thanks for Reaching out!
I hope you are enjoying your Co-op ARD. I'm assuming you are looking for rim tape that supports a tube setup. If you are looking for tubeless let us know because that is a different answer.
I really like cloth rim tape because it's easy to install, stays in place and creates less abrasion on the tube. you would need a size medium, in this case it's the 16 mm size. Here is an option that I would recommend for a set of Velox cloth rim tape.
pro tip: as you are installing the tape put a pencil through the hole in the tape and the hole in your rim to keep it aligned, make sure all the holes or nipples are covered, and make sure the sides are smooth to limit tube abrasion.
Thank you for your quick reply. This is very helpful! Yes, tube setup. I'll give this a try. For some reason the tape that came on the rim wasn't staying in place and seems to be causing flats.
