Took me many days, and curses to seal a set of “tubeless ready” Conti X-Kings Race Sports. Not sure if schwalbe will be the same but sidewalls were VERY leaky, and weren’t the easiest to get the beads to seal.
Ended up scuffing the insides with a plastic brillo pad, then mounting them with tubes for a couple of days, (they were a lot easier to seat and seal then), Adding ALOT (ilke 400mls) of stans to each wheel. Sloshing it round and leaving on a bucket over night, alternating sides. Bath check after first night had it down to a couple of pin pricks. Another night had them 100% sealed.
Used the Stans syringe to remove all the sealant leaving a dribble behind (basically the bit that wouldn’t syphon out) and have ridden on them for a good 200 miles with zero problems.
Shaved a good 600 gms off the previous set of Panaracer UST’s that were fitted.
