The title pretty much says it all.

LG launched the Sprint at the '15 TdF, saying that it sat between the Course and the P-09 in terms of aero.
Team Europcar were wearing it at the time.

Since then, it seems to have dropped right off the radar.
Nobody seems to be wearing it, and it never figures in various aero road helmet shoot outs (despite the Course often still being a part of these).

LG usually get their aero stuff right, so I'm curious if this helmet was a lame duck.
Was it poor quality? Not as aero as claimed? Poorly marketed? Unfairly overlooked?
