when buying used cranks...
can anyone give me specific details on what exactly i should be looking for to make sure there worth the cost.
im hoping to buy used profiles for 50$

make sure the splines on the spindle are good and arent stripped and also make sure there isnt rust or if there is jst surface, also check for cracks around the pedal bosses and the spindle bosse, make sure they arent stripped either*

make sure the hole where the bolt goes through isn't dented, so you can use a 14mm socket on it instead of a screwdriver and hammer
