Hi,
I recently bought a late 70s Schwinn Twin Sport Tandem. The only problem is that on the right side on the front crankset, there is a problem with the pedal. The pedal feels like it oscilates up and down as you ride it. It's the same feeling you get when you ride a bicycle with a bent crank.
I don't think the problem is the crank, it's how the pedal threads into the crank. The pedal doesn't sit square to the crank. It's out at an angle. I took out the pedal and gingerly threaded it back in. Still the same problem. I think someone had cross threaded the pedal into the crank threads at some point.
Is there a fix for this? I might consider replacing the crankset, but I don't know how easy it would be to find a replacement or where to even start.
Thanks
Rod Wylie
