I got these for less than $50 from Bike Tires Direct to replace the awful Orange Donnely CX tires that I had on previously. These tires are superior to them in every way.
These tires roll really fast on both road and Gravel and have a buttery smooth ride even at 60 PSI. On the road they really shift at 60PSI and the grip seems excellent. I have ridden about 70% Road and 30% Gravel so far and have been very pleased with them.
The only down side seems to be the wear. I can see wear after only 260 miles and I was hoping for at least 1000 miles out of them. I will update in another 250 miles.
