Recently, my bike started making occasional grind/crack noises that I feel through the pedals. I'm guessing some sand/dirt got into the assembly (or whatever that shaft part is called, located between the pedal arm and the front sprockets). So, I wanted to open it up and clean it/grease it.
I took out the main lugbolt out of each pedal arm, but I can't get these pedal arms off. What exactly do I need to do to open this thing up? I see a small ring between the pedal arm and the assembly tube - do I unscrew that? Looks like I need some special tool for that.
Thanks.
