So I crashed my good ol' SS Outcast 29er and the pedal has bent into the left the crank arm, so much so that I can't even get the pedal off. I am planning on going ahead and replacing both crank arms and some new pedals.

I am wanting to do this as cheap as possible, as this is now a back up bike, I am just not sure on what I need to buy. I am pretty sure it is a square tapered crank, at least that's what it comes with stock, but I am including some pictures because it doesn't look too square, lol.

Thanks for the help guys and gals.

And excuse the pics, I ended up having to use my iPhone because as usual, the cord has gone missing for the digi.

The first pic looks like splines of an ISIS bottom bracket to me but I could be wrong cause the pics is blurry.

Motobecane shows square for current bike: http://www.motobecane.com/29/oc29.html

Look between the crank arms and bb shell. You might be able to see the square spindle.

BB looks like an ISIS. Get the appropriate crank arm removal tool for ISIS. Remove the 8mm bolt. Screw in the removal tool all the way . Then crank on the handle till the arms come off.

So I am looking to purchase new crank arms now, would these work?

Yes, Gravity is FSA's freeride/am/dh brand. It will work, but you will need to see if your current BB is the correct length.

You can just measure with a tape measure the BB spindle end to end. If its 118mm, your golden. If not, then you need to get the correct length BB.
