Not to get too nerdy but, these tires test faster than most gravel tires on the rolling resistance website...I run the 2.2" version on my XC bike and can confirm that they are fast, but with better traction.
I was really hoping that 2.1 Thunder Burts would fit in my frame. They roll surprisingly well (BRR data backs it up). Thicc tire pimp, Dylan Johnson, ran 2.2 Race Kings at the recent Midsouth race. Adam Roberge ran Pirelli H 50s at BWR Utah. Other pro gravel racers I follow are moving incrementally wider. This is the stuff that has me interested to try Thundero 48s on my bike. BRR data indicates only a small penalty in Crr over the Thundero 40s, and the extra cushion is likely to be faster over rough terrain.
