I just bought it yesterday and no, it's not an x-mart bike. it's a Jamis Coda Sport that I bought from the best bike shop in my town

after a short break-in ride around the neighborhood, I rode it into school today (2.5 miles, my regular commute) to turn in a take-home exam. I was stopped at a stop sign about 2/3 of the way to my building (it was on campus) and as I was taking off again my left crank arm fell right off, with the pedal on it! thankfully traffic was light and there was no one behind me. I yelled a blasphemous word and stopped in the crosswalk to pick up the crank arm and walk it over to a spot that was out of traffic.

I called my dad who lives nearby and he was able to give me a ride to the bike shop, and like an idiot I tried to put the bike in the backseat of his car (after taking the front wheel off of course) which further compounded things, I found out the hard way that it wouldn't fit and I now have a bent front fender, damaged front brake, and broken lock mount as a result.

I just got back from my LBS, they were really nice, and helpful, as they usually are. my LBS rules by the way, best bike shop in town like I said, I've been going to them for a long time. they're fixing all the damage for free since I got the bike there... apparently the bolt was missing from the crank arm that fell off (either it fell off or just wasn't there in the first place). so they are going to put a new bolt in and show me how it is bolted in so I feel more confident about riding the bike again, which is really cool of them. I'll probably still be skittish about riding again for a little while though. out of the 50 or so Jamis's they have sold a year in I don't know how many years, I apparently have the dubious distinction of owning the ONLY one that this has ever happened to.

just goes to show no matter how safe and conscientious (sp?) you are and no matter whether or not you do your homework, stuff will happen nonetheless

Of course they're nice to you--can you say lawsuit? Mistakes were made, but really, that seems a bit negligent--they should have taken it on a test ride and then checked it afterwards.

Chin up! It gets better from here.

I actually test-rode the same bike the week before (test ride went great, nothing wrong with it then) and they put it on hold for me

seems more like a manufacturer's defect than the fault of the bike shop... they were genuinely surprised when I told them and its very unlike them to sell a defective bike

I'm a little scared to ride it now, which sucks, and I know I shouldn't be but it's hard not to

Not a manufacturers defect. When the bikes arrive at the LBS, they are assembled. Whoever assembled it should have checked the bike over afterwards to make sure they did it properly. This is why the repair is free, either it wasn't installed at all, or they didn't tighten it and it came out.

O-dog -- glad to hear that your breakdown was minor. Also glad to hear your LBS is backing up the bike they sold. The good ones always seem to support their customers. I wouldn't worry too much about riding in the future, the chances of such a significant failure happening in the near future seem slim.

Since it sounds like you are new to biking I might suggest that when you pick up your bike from the LBS you go over it with the mechanic. Check for open holes and ask why they are open (just to make sure there are no more missing bolts or pins). Look at screws and bolts that aren't screwed in all the way (some shouldn't be, so have the mechanic take a look and tighten anything that should be tight). Also you should look over how the brakes and derailleur look when everything is set up correctly. Once you have a mental picture of how your bike should look, you can start to give it a once over before you ride it. It won't take but a minute to spot anything that doesn't look right and fix it or get it fixed before you have another breakdown. Good luck with your ride.

thanks... very good advice, my LBS actually said they would give it a thorough lookover with me when I came in to get it

yeah I'm still quite new to biking, I've only been doing it seriously for a few months

Crankarms are installed at the factory, not at the shop. They should be checked, yes, but you should also know what you're talking about before blaming the shop for a poor install.

Bike books written in the 1970's often suggested having the crank arm bolts tightened when the bike is picked up, again after a hundred miles, and again after about five hundred miles. There seemed to be a belief that it was common for the crank arms to get loose during the break-in period, and then stablize.

I've not seen similar advice in "modern" repair manuals. I don't know if that means crank arms are less likely to get loosen than thirty years ago, or modern authors just don't think the "tighten, re-tighten, re-tighten" routine merits discussion.

But, when I take delivery of a bike, old or new, I ask my LBS to tighten the crank arm bolts, and I usually go back for a check-up in a few weeks. This can be expensive...I seldom leave the LBS without buying something or other...

Whether or not it was the fault of the LBS or not depends on how Jamis sends the bike to the shop and what their definition of "dealer ready" condition is. Quite often, "dealer ready" means the cranks are already installed. Still, if that was the case they should have checked for it and let Jamis know. Either way, good job on them fixing it all for free and glad you're back and running again. Glad you've got a good LBS.

I know how bikes come in the box (I built mine from the box), I also don't think this should have happened. This is the difference between a Wal Mart bike and an LBS bike. I blame the shop for this over 100 percent. The previous poster said it was manufacturer defect. If the cranks have the problem again, it is a defect, not Jamis, but the crank or bb maker. The bike should be checked over before leaving the LBS.

Who do you feel is responsible for it? If it was your bike, we'll say.

I checked my bike over upon purchase which is what a LBS should have done. at 120 miles the cranks were adjusted again.

My point was to correct your statement blaming the shop for incorrect installation. As I said in my previous post, they should have checked the crankarm bolts. They quite possibly did-none of us know for sure. It's rare, but even properly tightened crankarm bolts can occasionally loosen.
As far as blame, I'm not one to assess blame without knowing all the facts. That's never stopped anybody on here, though.

Fact. First time out the fricken crankarm falls off. Lets see,if you drive away in your new car and the wheel falls off,your going to blame the place you bought it from. The bike should have been checked by the shop no matter how it comes to them,they are at fault,come on. So we shouldnt buy online so we can pay more at the lbs to support them but something like this happens and its in question?

Fact: You have no idea if they checked it or not. If you say otherwise you are a fool.
Fact: Truvativ just issued a couple service bulletins about crank installation issues. Seemes that some of their cranks require complete removal and reassembly to properly seat on the BB spindle. They recommend at least two complete removals/installations. Didn't matter if you had the cranks properly tightened, they would loosen up. We didn't get this info until after I called them with an issue on one of the affected bikes. If the shop hasn't had a previous problem with it and hasn't received the info from Truvativ, how is it their fault?

I'm sure you already knew that the shop had received that info and decided it would be fun to ignore them, because otherwise you wouldn't be so certain that it was the shop's fault, right? As I said before, it's funny how quick people on here rush to judgement, even without anywhere near all the facts.

Look, glad you are OK... But I am here to tell you that I have done that to myself... I was doing my own wrenching and was called away by my wife to take care of some litttle task for her (doesn't she know that working on my bike is #1).

I forgot to tighten the bolt on the chain ring side. I had put it on tight enought to check the play in the BB and the chain alignment, but forgot to do the final tightening. Couple days later and I cannot seem to keep the FD in the gear I want... I glance down and the chainring is wobbling all over.

Yup, loose bolt. The dust cap kept the bolt captured, so nothing fell all the way off, but I sure felt like a dufus knowing I did it to myself.

It happens.

Hey the LBS should try to at least let you know they are human and throw a free water bottle your way.

I had a friend who had a new bike that kept losing it's crank for the first few hundred miles. I think it is better now though. The bike was a low end bike though. Don't know about yours.

o-dog: I think it's pretty standard for some kind of weird crap to afflict you when you first start commuting. Mine was the "Attack of the Flat Tires" and yours was the crank bolt.

Don't worry. Stuff happens to everybody. Commuting gets better the longer you do it.

update: I took it to the LBS and they put replaced the crank arm, put a bolt in, then made sure all the other bolts and screws on the bike were tightened down, and they said basically what everyone on here was saying, that the bolt was never put in to that crank arm

ran like a dream on the ride back

now the front brake is out of alignment so I gotta take it back in today

I'd say it's more like a mid-level flatbar roadie... here's the exact model: http://www.jamisbikes.com/bikes/06_codasport.html

yeah that's true... technical stuff happens, it did with my MTB too (had to have a new stem and new handlebars put on it recently) ... I've just never had a new bike have technical problems from the outset... it was a little worrisome

You know the common time a bike breaks down or has something wrong?

When you first buy it.
