Converted the Trek XO2 to 1x flatbar. 42x13-40 gearing.
Snappy and light. 42x40 is a little undergeared, but ok for the most part. Running 35mm G-One tires currently - think I will go bigger. Wide flat bars (640mm) feels really stable but on descents I need to not forget that it's a rigid carbon fork and pick the right line.
