    Hard to tell with wind noise, but could be chainring/front derailleur rubbing. Looks like it may be an aluminum frame and (pardon me if I’m mistaken) but by looking at your legs you look like a bulkier chap. I had the same issue (110kg) with my aluminum bike, big strong legs and too much torque for an older aluminum frame. Was flexing at the BB and causing the chainring to hit the derailleur.

  2. With this kind of thing I usually check/regrease/retighten (in this order:

    * Cleats
    * Pedals
    * Crank bolts
    * Chainring bolts
    * Quick release / Thru axle bolts
    * Saddle clamp
    * Seat-post clamp bolt
    * Cassette lockring
    * Bottom bracket
