Because the V20c is focused on high performance, the typical V20c rider would likely opt for road racing oriented drivetrains.
There has been some discussion about using a Rohloff on S40, and Q series bikes. I used a Shimano IGH on a T50 for a couple of years before switching to a conventional drivetrain. It worked just fine, however I needed more climbing gears. I thought about Rohloff but the cost was prohibitive (the costs was more than my whole bike) and the torque arm configuration would have been difficult to fit.
