Got three rear flats since March. Two were field repaired - a pain with the clutch and the chain requiring a certain orientation re chain ring teeth. Hell of a time getting the wheel back, woven into the disc brake and derailleur! First flat was a staple - both legs nicely planted in the tread. The middle flat was a real gash and the tire was trash. A friend begrudgingly picked me up. Bike shop replaced the tire and tube - worth every penny!
I don't know if tubeless is in my future or not - still debating. Or, also, just different tires.
