The crank set is a TruVativ Firex 44/32/22 w/Isis Spline... is there a way I can just replace the arms for her and also where can I get a replacement or whatever really really cheap? it is a 4 arm crankset and I believe the arm is 175 mm...thanks a bunch whoever!

Also I guess I should mention it's a 4-arm system...

You can save the cranks by having the shop Install Pedal Helicoil $15.00 each.
or...
You might try the warranty replacement route on the cranks, or at least see if the shop will give you some concession.

No they are for a square taper bottom bracket, not ISIS.

Are 175mm crank arms too long?
