IRC Boken Plus Tubeless Gravel Tire (Black) (650b) (42mm)
I've put about 100mi on these now with 30mi of gravel and some singletrack. Tires are setup tubeless running 45psi. The tire rolls fast, have predictable handling characteristic in varying conditions, and are easy to mount. I would buy these again.
