My rambler GT has about 500 miles and the top chain guide tube has worn through. The chain is now eating the bottom of the seat frame and the seat bolt. Anyone else having trouble? Looks like the force of pedaling is pulling the tube up against the seat bottom. When slack it drops about a quarter inch. Time to go back to idlers I guess.

Chain slap means the chain is too loose. Loosen the rear wheel nuts, pull the wheel backwards until the chain is taunt, then tighten the wheel bolts uniformly & snug.
Rover as well. Axle is all the way forward in dropout. We have internal
hubs.
ripple also happens with slack chain with an igh - unsmooth pedal strokes can cause the chain to hop the rear wheel sprocket, wear down the teeth as well. a tube will limit the ripple on a too loose chain and help compensate for axle-slip as well as protect the frame from being sawed by the chain.
axle all the way forward into the dropout solves axle-slip as well as keeping the rear wheel aligned with the frame.
