What worries me too is the negative effect that all the recent chemical, blood and mechanical doping scandals are having on the public's perception of the sport. As it could lessen the number of potential future devoted cyclists that could eventually carry on the C&V movement in the future, because they might be discouraged to participate in a sport that most of the public might consider as "sleazy" at the highest levels.
The cyclocrosser recently caught for mechanical doping takes the cake for me. Just utterly stupid and disgusting!
