let's think a minute about worst case scenarios here. some cringe poser joins your group ride with an slfake. That day, it's tempo day, you're going 45kmh in a peloton, he takes a pothole, his frame self destructs, and he causes a crash for himself and others. to be honest, I would finish him off with my own fists.
we havent had reports of frames self destructing for years on this forum, those are horror stories of velobuild frames from many years ago. Now that weight is all the rage again, i really dont want to ride in pelotons with people on super light & unsafe frames. My open mould is a tank.
That is a problem.
Same risk if you ride in a normal amateur peloton made of bikes of 4-5 years, maybe entry level, with no-manteinance etc.
Or do you ask to the cyclists you follow/cycle with if their bike is “safe” ?
I get your intention and I partially agree but, at the end, I think that anyone can buy the bike they want, fake SL8 included
