This looks weird...is it right?

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?
Thanks!

unless you know what you're doing and have the tools, take it to a lbs

You're right, there's something odd here

Looks correct. If you measure from the center of the frame to the center of each crank arm, you will probably see that the distance is equal or nearly so.

I'd get it checked out. I've never seen a gap like that before.

the gap looks fine, but I'd still have an LBS give the whole thing a once over.

I don't necessarily see a problem. Different bottom brackets have different spindle lengths that can affect the spacing of the cranks.

I'd have an LBS look the bike over and snug/torque any bolts and adjust the brakes/derailleurs....for your safety!

that's why its difficult to tell from the pic...did they use the right BB?, or are they using a longer spindle because they're using the wrong peddles and need that length to clear the chain stays?

best that someone who can see what's going on here take a look at this

There is no way that somebody can look at this picture and say there is something wrong. I see absolutely NOTHING wrong. But I can't tell if your bolts are tight. If you are concerned recheck them. There is a 10 mm head holding that crank on.

from the pic it looks like you can get a finger betwen the crank and the BB, perhaps in canada we build them different, but I doubt it.

I've yet to see a bike with what looks to be a one inch gap, my only thought is that they've used a longer spindle to give the crank enough room to clear the chain stays

what you think?

Why do people insist on repling when they have no idea what they're on about?

I think it looks fine. a bit on the long side maybe, but you are never going to get it so short that debris won't fly in there.

Spindle length should be determined by the drive side chainrings and the crankset.

How does the type of pedal have any bearing on the bb spindle length? the pedal is 2cm ( or more)removed from the inboard side of the crank. If the crank has clearance, you are not going to find a pedal that will give you an issue.

The Q factor might be on the high side, but again it looks fine, as long as everything is tight

I can tell you from experience that these posted pics online distort sizes severely at times. I seriously doubt there is an inch gap. And you can get a finger between the crank and bb on the bike that is sitting here in front of me. It is only my pinkie finger but that is still a finger.

Again, you can find NOTHING wrong by looking at the picture. Even if you were right that the spindle was too long, the problem would manifest on the other side of the frame. And even then we are not looking at a safety issue rather an issue of performance.

BTW, does my chain look weird...I think it might be too big for my bike.

Actually, it's an 8mm.

Does the crank arm feel loose at all? Any wobble? If not then it's fine. The angle of the picture and the flash make the gap look bigger than it is.

If your pedals are on the inside of your cranks I don't think you need to give others advice
