Hi, i bought a used bike with an optis insert. Its not holding air and i was trying to refresh its sealant. Checked youtube and google how to do it correctly but it keeps leaking air in this hole. I cant seem to find info about it. I dont know what km doing wrong. Any help is appreciated before i ditch this thing in the trash.

That looks stupid as shit, I just did a quick google of it. That is the kind of thing some young rep would bring into our shop selling it as some insanely cool feature worth upselling to customers.
Someone tried to reinvent the inner tube. Then just invented a second inner tube to go over your other inner tube.
Can we stop reinventing something that works? A properly set-up tubeless system works great, and doesn’t add 80$ to each wheel.
Run it if you want, or ditch it and don’t ever worry about it again.
Someone reinvented the tube but worse… ffs ditch that trash
Fellow optis user. I had this same issue. I just started from scratch and installed the optis on the rim again keeping extra attention to make sure the little valve straw stays straight when installing the optis. I found letting the optis sit for a bit inflated at 20psi before installing it helped stretch it and made install a lot easier. I’ve done a bunch of riding on mine since I installed them. The optis air chart is a good starting place for fine tuning your pressures, but there is absolutely a noticeable difference with the optis installed. Have fun.
