Familiarity: I've put it through the wringer
Wow what a difference going tubeless!!!!! They are amazing! The wheels have just enough aero, and the tires are exceptional.
Things to know: Shimano/Sram option works with 8 and 9 speed cassettes (from experience - mine and wife's respectively)
Tires come mounted on, just inflate them, and use the syringe to inject some sealant into each wheel through the valve -- you remove the valve core with a small included plastic tool (any online vid will show you how) -- super easy to install.
Don't get confused by the "front" and "rear" markings on BOTH tires. Just orient them based on tread pattern when you stand over the bike as you would be riding it and look down at each wheel you should see the tread go like this: / \ and NOT like this: \ /
Yeah otherwise super fast, super aero, super nice rolling resistance, and most importantly, seem bomb proof on the potholed roads of Boston.
