So now I got to repair a ******** rear derailleur
I've been riding strictly singlespeed for the best part of the last two decades, and one of the reasons is because I hated troubleshooting derailleurs. But now my son broke his 1x8 speed bike (actually his friend) and so I must try to troubleshoot and repair the mess.
HOW IT HAPPENED
His friend changed speed from standstill and then stepped on the pedal. After some cracking he rode the bike, but after this the highest speed the chain on the largest sprocket) wouldn't work well at all.
THE SITUATION NOW
- the chain would fall off the largest sprocket and onto the inside, between the sprocket and the spokes. Also, the derailleur is hitting the spokes.
WHAT I TRIED
I tried to play with the cable's tension by turning the tensioning nut. I achieved that the chain would now stay on the largest sprocket, for the most part (though it does fall inside from time to time when going from 2 to 1). HOWEVER, now speed 8 is f*cked - the chain never goes onto the smallest sprocket. It stays on the next-to-smallest.
