The bike is a Merida Speeder 10 flatbar and about a month old.
I've noticed a rhythmic clicking from the rear wheel. At first I thought the wheel may be bent and the break pads were catching, but that is fine. I also noticed that the noise stops when there is load, eg: when I am pedaling up a hill.
The noise occurs both when cruising and when free wheeling. It happens in any gear and at any speed.
Could the bearing be worn?
