Hello all! My bike will inconsistently shift. I can't use the bottom gear, the chain slips off it and rubs on the wheel. The bike doesn't shift at around gear five out of seven, and then when I go to six it's on five. When I finally try to put it on gear seven, it shifts to six, and then immediately after slips a bit and shifts successfully to seven. I think one of the limit screws is off, but after doing some further research it seems that the derailleur hanger is bent. It make more sense to me given the situation. It took a fall on the drivetrain side on a trail a couple days ago. I don't have a park tools DAG 2.2 or similar, so I think I would have to resort to bending the part. What can I do to fix it? Yes, this is not a fancy bike or anything, which is why I would rather fix and spend less money. If I'm going to spend more money, I'd rather spend it on something with a greater longevity. https://www.walmart.com/ip/Schwinn-Signature-Men-s-Chute-27-5-Mountain-Bike/710567794. I spent only $200 on this, and the only difference is the grips and the seat, which don't have an effect on the drivetrain i would imagine.
Also -- Is there any way I can take the Shimano S-TEC class without working for a bike shop? I would like to be able to do these things on my own, and I plan on owning a bike in some form for as long as I am able to ride one. If I can't take the S-TEC class/certification (i just want to learn, but working in a bike shop would be a cool summer job for a college student), what other options do I have in the way of basic maintenance and repair education? I'm not looking to spend much money, but I will if I need to.
