Just watching video's of the 9 year girls to see my Imogens competition. Take a look at the final. The US girl that wins it has the wierdest riding style I have ever seen. It must be because they clip in at such a young age. It's almost like pedal, pedal,pedal everywhere and hold on,it's like she gets whiplash on every jump, I'm sure if you were on flats you just couldn't ride like that
Have a look here , 9 year girls final.
