An aluminum pulley would be very weak. Can we say hand grenade?I would expect these to fail like the aluminum water pump pulleys due to stresses leading to brittleness. The rivets will come loose as well, sooner than later. The corner radius is too small.
There have been reported problems with the new EC aluminum pulleys on the MB forum. There were large gaps that are supposed to be reduced with use. Where have I heard that before.
