1.0 wheelset looks to be setup for tubeless and I’m running it tubeless but it’s not allowing most of my tires I’ve tried to sit in the rim groove well. Am I wrong in thinking these are tubeless capable? By the way the previous owner loved his bike HARD and kept the battered frame for nostalgia. I used the wheelset on a budget crux build and the colors match so well it’s insane
Those rims are defniitely tubeless capable, and are pretty much always ridden tubeless.
I would make sure the condition of your rim tape is good as a first step. Nicks, wrinkles, and holes could make mounting difficult or impossible.
After that, you simply need sufficient pressure in the tire, and sealant in the tire, to push the tire bead up and over that tubeless rim groove until it makes the popping sound. This is usually around 40-60 PSI with gravel tires, depending on the tire. Once seated, we back them down to around 20-40psi for riding.
