Day 3 of new bike... Left Crank falls off in street

Yeah... this was a shocker...

I get on my bike to start my commute home... and in the front of a MALL.. my left Crank arm falls off.

Luckily I was sitting down... so aside from some wierd looks from people..nothing drastic happened.

anyhow... gunna go in to fix it tomorrow...

OK.. with that said... I am thinking about buying some Lighter Crank arms... I never realized these things would be so heavy. Any recommendations?

Thanks .. BTW.. my bike is a 2006 Specialized Rockhopper.

Well the crank arm threads are all chewed up .. and the crank wont go back on.. not to mention I dont have the bolt that held it on anymore.. couldnt find it in the street.

Just seemed kinda rude to give a NO PIC = NO RESPONSE answer to someone that just had bike problems.

I'm too tired to take a picture of my bike just so you nutjobs can oogle at my new bike.


so... nevermind I guess.. but for those of you who want to see a picture... here ya go!!!

The crank coming loose can actually damage the crank making it impossible to ever get tight again. When it loosens up it slops around, opening up the taper or splines. That means it won't fit anymore. A picture might let us see if this is the case. So how about a pic of the inside of the crank arm and the spindle of the bb, close up and focuses.

That looks pretty chewed up. It's always worth a try, but my guess is that's done. Bring it back to the shop before you do anything else with it. Some shops (or even just shop guys, this time of year it might be "the new guy" who put your bike together) forget to check crank bolts when they're building the bikes. It happens. I did it when I was new at a shop and the same thing happened. My boss wasn't happy because he had to shell out a new crank arm.

Cranks bolts don't just come loose under normal or even hard riding if they're properly torqued. Bring it back to the shop, keep a cool head, and ask the manager what he's going to do to keep a statisfied customer (maybe not in so many words, but you get the idea).

Do the crank bolt threads inside the BB look stripped?

Well I bought it at GOride in Redwood city (san francisco area) ... this is the second bike I have bought from them.

As for riding.. I havent even taken this thing on dirt yet.. its just been city riding.. so yeah..nothing crazy in terms of stressing the bike.


But as far as GoRide in Redwood City...
So far they have been very good to me... so I am not too worried. But yeah .. I will let everyone know how it went.

NO.. they dont. Which would imply that perhaps it was not tightened enough. Right?

yup. Or maybe they didn't put the bolt on at all, or took it off later and forgot to put it back on?

Sorry, I was just fooling. I just say that to everyone, I'm too inexperienced to give you a thorough answer besides "put the crank arm back on".

I'm saving my pennies for a new BB+cranks . I'm now heavily in debt , so cost is a consideration . Most of my riding is very technical XC with lots of climbing and rocky downhills . I'm light on my bikes , but ride lots of miles . Sorry to hijack the thread , but it is along the same topic .

RaceFace w/external BB...Evolve XC or DH - should be able to find them online for ~$150. PricePoint has them for around that price and good prices on the Deus and Atlas cranks also.
