Today was the day every modern cyclist dreads; swapping out tubeless tires.
I only had to replace the rear (which was triggering because it was a different brand and now my tires don't match) and amazingly, it only took 20 minutes. I only put in about an tablespoon or 2 of sealant in there, not sure if that's enough.
This thing is a godsend, made it soo much easier.
