I'd went to a small trip to climb some small hills. After about 500m the pedal went down and won't go up. The clutch cable was broken.
Even so I still wanted to climb to the hill and I did it.
First I thought the only problem is broken clutch cable, but then I realized it's something bigger. The clutch got stuck and I can't change the gear up or down. I probably need to visit my mechanic on January ..
