I volunteer at a non-profit shop and one of the most common causes of donation is a broken shifter. So I get to take a lot of them apart to try to fix them. A few have the indicator. It's never a...

I just worked on a donated bike with those extenders. The left pedal was stripped out of the crank arm (square tapered). I blamed the extenders and I agree yours could be at fault.

How big a tire can your bike take? Take the current tire's minimum clearance to forks and stays in mm, divide it by two and add it to 25 for a rough idea.
