Help with crank noise

[fritzschantz]

Hey, can anyone offer any suggestions as to the nature of the sound in my bike that seems to eminate from the bottom bracket? Starts after riding a couple miles. Gets progressively worse, and I can start to feel it in the left pedal. Here is the video:

I have another super32, so I used it to swap out the rear wheel and crankset, pedals, bottom bracket assembly. Still there. Maddening.

Any chance your chain is rubbing the kickstand?

I'm going to make a suggestion, but please don't be insulted when I do--I have no idea of your level of wrenching experience. You've seemed to have swapped out nearly every possible part, so...I'm left to conclude that something in the order of reassembly or adjustment is possibly wrong. The bottom bracket is adjustable and uses caged bearings, correct? Is it possible you've installed the cages backwards? The closed side of the cage should face inboard, toward the spindle race--the open side should face toward the cups. When properly tightened, the crank should spin freely without binding, but have no lateral play side-to-side. It's a mistake I've made many times, or watched others make, especially when they're rushed. Outside of any obvious galling or damage, there's little else to go wrong with the BB. Again, no slight intended...it's the best I can suggest with nothing more than a video clip to go on.

Thanks RustySprockets - Not insulted at all! I'll pull the BB apart tonight and check the bearings orientation - entirely possible! I had a PM that suggested using better pedals too.

Sounds like something might be loose.
In addition to ensuring that the bearings have the correct orientation, recheck and make sure that everything is tight: fixed cup and lock ring in bottom bracket, crank arm to spindle, and pedal to spindle connections.

I had mine apart 3 times. Those bearings and cups are cheap, when I replaced the bearings with some from an old raleigh 3 speed, they were good.

Pulled the cranks off and found this suspect out of square crank:

and from the crank side:

So I pulled everything out. Installed a bottom bracket assembly from a 90s Raleigh Technium mountain bike. Took cranks and pedals off of a giant hybrid. It was a triple ring crank, so I drilled the spotwelds and pulled the large and small chainrings off. Not optimal set up, but it will get me by until I can get a proper crank.

So we shall see.
