Hi all, I am new to zwift and cycling. I am doing the FTP builder 6 weeks. There is a training where it requires 10 seconds sprint of 295 watts from 95 watts of power. That means you need you need to have high cadence while shifting gears. How do you sprint switch gears very fast without almost cross chaining and without the sound of breaking your gears during the shift.
Creaking sound bothers me with shifting. Is it normal? I am using a ultegra 6800 mechanical groupset.
