I installed a set of normal tires on the rims, and initially tried 40-50 psi to get them to pop, but it took 80 psi for the beads to seat. (Note: this was the line in pressure, tires were only filled to 40 psi). I let the tires sit as long as possible to stretch out the carcass, and then pulled the valve core and filled them with the supplied 2 ounce bottle of sealant. I re-inflated, and shook the tire while rotating it to get the sealant up into the sidewalls. After a couple of minutes laying on each side (after doing the shake step) the tires were topped off to 40 psi to sit overnight. I tried a couple of UST tires, and they popped on without any problems, though some of the sealant from the previously installs made the job easier, and kept them sealed better (and longer).
I was easily able to install/remove the 9mm and 15mm adapters on the front hub, since they simply slide into the slot, but I was a bit confused on the 20mm set? It turns out to be a very simple, albeit primitive, process. Just place the 20mm adapter into the slot followed by the ring, then using either a 1 inch PVC coupler (my fave) or a socket, give it a good couple of hits with a mallet, and the ring seats nice and tight! To take it off, insert a 20mm axle into the adapter about a 1/2 inch, and ever so slightly lever it sideways and the ring pops off. Thanks to Scott at Sun Ringlé for the pointers on what he calls the Caveman approach, which I happen to find effective, “Simple is, is simple does.” I think it’s really nice that the front wheel comes with all the adapters you could need (9, 15 and 20mm), while most manufacturers charge you extra for additional versions.
The rear hub came as a 9mm x 135mm, but you can purchase an adapter kit for 12mm x 135mm or 12mm x 142mm, for $20 each. The non drive adapter slide off and on, while the drive side is threaded on. To install/remove the drive side adapter, mesh the adapter kit tool into the notch on the non drive side axle. Then use a 17mm cone wrench on the slot of the drive side adapter to tighten/loosen, while holding the opposing non drive side tool. It is a simple and innovative idea that allows their hub to be used in the vast majority of the rear axle system on the market today.
