Definitely didn't work for my carbon bike. It's annoying because sometimes those are put in place on very minor - major road crossings and those are dangerous to cross on red light (and the minor roads are exactly the ones you want to be on the bike). I had 2 of those on my usual loop when I lived in Poland. Sometimes I just waited for a car but especially on weekends I needed to risk it and run the red light as otherwise I would be stuck there for a few hours.
