Hi have a halo 80 mm tundra rim can I use tubeless?

If so is it straight forward?

Yes, but it’s not super easy- if you look in teh massive Calibre Dune thread, it’s the exact same rim just with different shaped cutaways. I got hte best results with a mix of electric tape and jiffy foam, and the easiest results with foam and a cut tube. But it was always a pain in the cock- totally worth it mind.

i did mine ghetto tubeless because it failed a few times trying the tape way, ghetto for the win 🙂

What’s the foam for?

Builds up the rim bed a bit and takes away the gap- makes it way easier to inflate. It doesn’t do anything once the tyre’s up

Thanks so what size inner tube would I use?

I used a schwalbe AV10- it’s just barely wide enough so you have to cut it carefully, but it’s cheaper and lighter than the AV10D that most people recommend.

Cheers
