I have a 1000 too and might try it in a gravel race sometime but mine was found covered in appliance paint and was the victim of a flat bar conversion. If it was pristine I might just sell it, I've seen a few for sale around Ontario so they aren't unobtainable yet.
My 1000 came alive with some newer wheels, the stock ones are really strong but kinda heavy. I also used it for brevets and it really does well in that capacity.
