Hi there,
I'm new to these boards. Been lurking here and there and decided to register as had a recent problem with my bike.
Had it for about a month after becoming interested in fixed-gear bikes, newbie you could say, i suppose, so my knowledge of mechanical aspects is limited.
But anyway, last time i was using it, after a friend had been on it, I noticed the left crank arm was loose, not at all tight.
The image on the left shows the arm when it's at it's loosest, moves around and almost feels as if it's about to fall off (don't want to try taking it off). The image on the right shows the arm when i've pushed it in as far as I can (with my hands), it's less shakey but still loose.
Not sure how to tighten it, guessing it may be these two holes at the end..
So yeah, is that where the problem is, do I need to tighten these two holes with a special tool?
I plan on visiting the bike shop tomorrow to ask/borrow tools, but wanted to ask here and know what to expect of them.
Apologies for such a long-winded post over something that may turn out to be so simple.
Thanks in advance.
