BTW, what is this spoke cards thing is all about? I've never seen it here in Japan. What's it for? To just show off? But are you riding THAT slow then so it doesn't come off? I imagine it would get in drivetrain and you'll fall off the bike. I don't even have spoke reflectors on my bikes, they're dangerous too. They DO come off at the speed of around 50 km/h or even less.
