I had to unscrew rear wheel to replace inner tube. I haven't fully detached it, just to the moment I was able to replace tube. After reattaching wheel I can't setup gears shifting (that's my first time actually). As I read in different guides I need to rotate adjusting barrel until markers are matched on speed 4, but using this barrel I'm able to match it only near speed 2.
What else should I adjust? Or have I done something wrong (maybe reattaching wheel)?
