The vast majority of cyclists - whether they are recreational, sports or professional are clean and do not need to take proformance enhancing substances ( apart from energy gel's and energy drinks ) to get the best out of their abilities.
Using Dwayne Chambers as a prime example, he is banned from participating at this summer's Olympics because he was caught taking a banned substance -and rightly so!!
Now back to cycling - a rider like Ricco will have time to reflect on what he did in the 2 year ban that is automatically imposed for a first-time drug-cheat ... it happened to David Miller and he has now seen the stupid mistake he made in taking drugs to enhance his chances of winning!!!
