Whilst watching the Tour I have a couple of questions I wonder if anyone can answer ?
1. Why do the riders only sometimes wear helmets,apart of course from the time trial helmets? When
they do,is it mandatory as they all seem to wear them.
2.In the time trials I presume that the disc rear wheel is to cut down on aerodynamic drag caused by
using spokes,but why only the rear wheel.Surely the front spokes cause drag as well ?
Thanks,
Sam Salt
