It's no louder then the original rollers, the skateboard wheels are turning maybe one 1/4 revolution each time it slides back and forth during normal riding. The actual tire roller sound is still louder. Maybe it's different with an all alu version, the wooden frame might quiet things too.

I'm definitly going to work on some side bumper wheels cause i kinda got cocky when i was ridding them today and slipped off the side when i was trying to sit back down

About the video, i'm really sorry about the crappy quality, my mom's HP digicam takes horrible quality, and really dark movies, i wish i still had my canon, it took much better quality movies but alas, i had to return it for financial reasons.
