Not sure if somethings wrong but there’s a humming that definitely doesn’t happen during my rides on road. I was just wondering if there’s something wrong that anyone can pick up? video humming/rubbing sound that changes in severity with gear changes.
Any help would be great as I’m a first time trainer user and newer bike rider :)
Thank you

I was under the impression that my bike was a 2014 sl4 roubaix. However, due to having a thru axle the bike mechanic seems to think it must be post 2017? Can anyone help identify which year it is? Thanks
