So I'm looking for a new cyclocross/gravel bike. The main things I need it to have is clearance for 27.5 x 2.1 mtb tires and the ability to run a tapered steerer tube. Also, I would prefer for the frame to have more of a cyclocross geometry as the long wheelbase of most gravel bikes doesn't appeal to me. I'm willing to consider any frame material. So any ideas or suggestions on frame/bike options?
