I ve been using wireless shifting for more than 5 years and never had a problem with it nor a stuck front derailleur. I am not saying that these problems do not exist but the number of bike changes are ridiculously high. So I have to ask myself how that can be. How can it be that teams with the biggest budgets and the best technicians have so many mechanical problems? Above all, it's also bad publicity for all the brands if so many bikes are exchanged every race.
Mechanical problems are part of cycling, but the high number of supposed mechanical problems makes me doubt it. Especially those changes when you don´t even see a flat tyre. Like Pogacar at Paris Roubaix.
Yes the first time he changed it after his crash at 37km to go and then at 20km to go. It's difficult to judge from the TV and its Paris Roubaix where riders have punctures but when a rider has a real flat tyre, you can see it. This was not the case. Maybe it was a slow puncture or maybe he just wanted to get rid of this bike like Cancellara back in the days. Same for MVDP who changed his bike 5km after Pog changed it. Maybe it's just a stupid coincidence, but some bike changes make me wonder. But maybe I've just read and heard too much about motor doping recently
These x ray scanners are rarely used. At least that's what the UCI president says. Tablets are used most often, but they are a joke. Even engines from 10 years ago can bypass these tests, according to Stefano Varjas. So think about what is possible with modern technology.
And as Marshall-Bell exposed even in the Giro, for example, there are stages where there are no controls at all. So the controls are a joke and according to insiders and even the UCI president, motor doping is technically possible and that is really worrying.
