I did 150 miles of the green mountain gravel growler trail in Vermont on my Giant Anthem X29er XC bike.
Locked out the back shock 90% of the ride and 1/2 locked the front. Tires were already warn down somewhat so didn’t bother changing out the treads. Still had good traction on the road, gravel, and MTB trails. Over all was very happy with its performance, though it might have been nice if it was a little slackier, head tube a little higher.
I do like this idea of a better gravel bike. The Trek DS I have for doing rail trails (dirt and paved) with the kids just does not feel as good.
