Yup, have them on my Giant Revolt, they've been great. Very fast for a 40mm gravel tire. Durability remains to be seen, but no issues so far.

I also put a set of Terra Trails on my other wheelset, they're a lil slower due to the larger tread, but still fast, should be good for loose/muddy conditions. The Speeds will most likely be my go-to for most of the gravel riding I do.
