Occasionally under load when taking off on the flat, I would get a crunch, then it runs smoothly.
After reading the other post I had tightened the wheel nuts but this has not fixed the issue. I have checked the yellow lines align also. It occurs in variety of gears. The bike was only 1 week old before it happened and it was next day after ride in rain.
I live in NZ and bought the bike in Australia, so taking back to vendor is not a option. For interests sake it's a focus planet belt drive.
