This evening I was going for a cycle on Zwift when the bike randomly stopped functioning as normal.
I was suddenly unable to shift out of the highest gear (smallest cog) on the rear derailleur. I’ve had tried to figure out what has happened but have been unsuccessful.
I’ve included a photo which shows the current tension when on the highest gear.
Is my bike broken? or is this an easy fix?
Any help would be greatly appreciated.
Thanks in advance.
