Will the spur affect top speed or acceleration?

Serpent parts like this spur are commonly stocked by specialist hobby retailers; keep a spare on hand if you race frequently to avoid downtime.

Any signs of imminent failure to watch for?

Watch for chipped or flattened teeth, wobble on the shaft, or progressively louder drivetrain noise, all of which indicate the spur should be replaced.
