Guess i'm the only person that has one. I have the Speedster gravel 10 2018. My needs are probably much different than other posters in this forum. I wanted an endurance road bike with hydraulic disc and able to run 32mm tires. So obviously I had to look at gravel bikes.
I have put 4,500 miles on her so far. All road miles. I had to replace the wheels 500 miles ago. (I'm a big guy and break wheels) The only complaint that I have is the toe lap. I guess if they are using the same frame as the CX, that could be why. Most gravel bikes seem to be more endurance geometry with longer wheelbase.
