Title: Slight vibration when rolling bike back and forth
Post by: joesedroid on February 12, 2023, 07:42:14 PM

Hello,
Up to 1600 miles on my two month old 2023 SS9 and was wondering if anyone else feels this when doing slight rolling.
I move my bike around quite a bit in the garage while sitting on it... and I know ive felt this when new, but it feels more pronounced now. I am almost positive its the chain links taping either the swing arm or how its touching the sprockets, its a very subtle but noticeable knocking/vibration at maybe sub 1mph movements.
I just tightened the chain to 1 1/4 inch and torqued everything down correctly, and before I did the adjustment the chain was very loose.
Just checking to see if anyone else hears/feels that behavior.
Thanks!
Joe

I am not sure if you describe the normal noise a chain drive makes. That might come from the bottom chain guard (sorry, I don't know the correct English word) on the swing, on which the chain runs. On my Ribelle the upper chain guard is not touched permanently, but the lower one is.

Contributing to the noise/vibration could be that the grease film on the chain had become thinner over time. I bet, if you use a really thick chain grease, the noise would be reduced considerably.

For me, I switched to PTFE-based 'dry lube' because I do not drive in wet conditions and I hate grease flying everywhere. With that special grease only a thin layer is necessary, but it goes without saying that the chain noise is much louder.
