Not Sure of the Significance
The publics sudden rush to support a successful BC track squad reminds me of the rush of support the English rugby squad got after winning the world cup, a few years later and no-one remembers them or their acheivements now outside of the traditional rugby fans.
BC is riding the tide of public adulation after the Olympics, and maybe one or two names will become household names (as did Johnny Wilkinson), but I doubt it will have any long lasting affect on the public perception of cycling as a sport.
I also don’t think that you can doubt Brad Wiggins commitment to cycling, to be at his level and be competetive requires 100% commitment, I just don’t think he likes the publicity caravan that comes along with this sudden surge of interest in BC.
