I have a Marin Hawk Hill 15" that I've been having for almost a year. A friend of mine completed assembly on it for me(shipped 90% assembled). Unfortunately I still haven't ridden it yet(work and life keeps getting in the way), but I plan on having more free time this summer so I've been messing around with the bike(installed new grips, bar ends, etc.).
While just giving it the once over, I noticed the left pedal and the crank seemed strange to me. I could see the threads and the pedal didn't look like it was installed all the way or properly. (Pics of this below) Sorry that they're not clearer. It just seems like the top of the crank arm should be flush with the frame(or whatever...not too sure with terminology). The way it is now seems like when I do go riding, dirt, dust etc. will get all up in there.
Does this look right to you? If not, is it an easy adjustment? I'm not too mechanically inclined, but I may be able to do it myself, or should I bring it to a LBS?
