I'm puzzled by what exactly constitutes the 'seriousness' of these urban MTBers. Is Pontefract the new Valparaiso? There are a few gnarly descents in Swansea for the taking, but from my desk I mostly see blokes on cheap mtbs trundling up and down the pavement all day in a manner that can only be described as pedestrian (see what I did there?). On the other hand I'm slack-jawed in admiration and wonder at the skills of the young men on jump bikes in Castle Square. Anyway, this thread is full of the sort of people who would've liked the cops to win in the ET bike chase.
