Dolan Pre Cursa / PreCursa / Track Champion

Mine gave up going up highgate hill with a bus behind me.
Under a year old and had used it on the track a few times, can't have roughed it up too much as the navigator pistas it came with were still true.
Sure there are plenty more out there that didn't just snap though.

Think that's the same one that was posted on page 4 of this thread.
