Hey all of a sudden when i ride and coast the chain pops off then after I pedal twice its back on. The crankset also moves with the bike if i push it as you would see on a fixed gear bike. Please help this is my only means on transportaion. Its a 2010 surly crosscheck

EDIT: when i push the pedals backward the rear delrailer gets pulled forward.

Gummed up lubricant in freehub stopping the freewheel pawls from releasing.. Try to free with a bit of spray lubricant (not WD-40), into the freehub, but not into the rear wheel bearings.

your freehub is stuck.

HorseHair, It's really best to teardown and relube freehub and wheel bearings.

My plastic spoke protector broke and when I coasted it would turn the cassette causing a dropped chain. The fix--rip off the plastice spoke protector.
