We just picked up a gently used 2020 Kona Mahuna with some entry level WTB TCS2.0 wheels. In my attempt to make them TL I noticed the sealant leaking out from this crack. Looks like a bad welding? What's the consensus?

I'm thinking of just putting the tube back in and keep and eye out for a replacement.

How's WTB warranty?

You can call them and see what they say about it, but at the end of the day, that's pretty normal (if on the 'less-okay' side of the scale) for how non-welded-seam bicycle rims are made: a piece of stock cut on an angle on the ends, rolled into shape, and pinned together. To be fair--as mentioned--that's pretty far out of 'normal'. WTB is usually pretty good about such things, but I wouldn't expect the world, especially if you didn't buy it new.

You could pull the tire, clean the area EXTREMELY well, and adhere a piece of tape across the rim sidewall, down to the hook, across the bed, and up the other side. Re-mount the tire, and cut the excess tape off at the top of the bead hook. You could fill it, too, with a flexible epoxy, but do it from the inside, so there is no danger of leaking into the rim cavity.

Thank you! It seems like the sealant did the work and closed it up. I'll take off the tire next week and put some tape on it to avoid any issues going forward.
