Henrik Voldmester Posted January 5, 2018 Share Posted January 5, 2018 My One S2 is two monts old and I hear now and again a short, ratteling sound from the wheel. The sound comes clearly from ether the left or the right side, and it is becoming more frequent. Any ideers why? Should I be worried? Link to comment Share on other sites More sharing options...
Rob Valley Posted January 5, 2018 Share Posted January 5, 2018 As it so happens i was thinking about the same topic today! Im pretty sure i have always had the crackling sound, but then again i have not rally had a chance to listen to any other wheels. Then i thought about if it would be nice with some soundfiles of malfuncioning wheels, maby even able to diagnose a problem. anyways i recorded my KS16 in free spin, hee you can hear the crackling in the start, also in high spin, but note in the end it almost goes away, but only for a second or two. Note: check your volume before playing the file 2018_01_05_14_33_07_1.mp3 Edit: there is also some resonance in the sound, might be i had it a little too close to the mic Link to comment Share on other sites More sharing options...

Mono Posted January 6, 2018 Share Posted January 6, 2018 As a non-native speaker I would have described the sound as sparkling or sizzling. I believe it's normal for the S2. Link to comment Share on other sites More sharing options...

Knifa Posted January 7, 2018 Share Posted January 7, 2018 I also get this sound. No idea what it is, it doesn't make the sound when the wheel is spun with the motor off. It only happens for me at slow speeds. Still feels smooth though. Every now and then a little stone or something will get kicked up inside the housing and it'll rattle a bit, but it always comes back out. Link to comment Share on other sites More sharing options...

Thank you for your replacement. Link to comment Share on other sites More sharing options...
