This makes for a "bumpy" ride home. Jumped the chain past the big chain ring on my dad's Vitus/Peugeot on a shake down ride to see what it needs and then jammed the crankset as the chain got to the pedal. Happened about 9 miles from home. I got the chain back on and hear a "noise". After finally stopping a 2nd time I finally saw the damage - sheered teeth from the upper pulley on the rear derailleur. Not the first Simplex I've had with this problem. The advantage was the faster I spun the less noise it made and more efficient the chain was going over that spot so it was still a good workout.
