Hey, I’ve just set up my first indoor trainer and am getting this humming noise on the down pedal, it gets better with lower gears but there seems to be more chain noise, where as in the lower gears it really becomes prominent. I have checked that my derailleurs are all correct and and chain and cassette are both new. Any help would be great thank you :)

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
