Freakin' sweet! Thank you so much for the info!
I bought new tubes and tires, bar tape, and lube today, so my $35 bike is now a $110 project
I took a closer look at the cassette tonight after the tire removal, and two of the teeth are worn on the big ring. It shouldn't cause a chain derail though.
Now, Does anyone know where I can get an original decal set for it?
