The bike in question:

The issue:
Came to work yesterday morning, no problems (apart from fat/weak/headwind).
Setting off home after work, immediately on setting off there was a high speed (multiple clicks per second), irregular clicking sort of noise coming from around the area of the front hub, almost like a cross between clicking & a grinding creak. It was pretty loud.
The speed of clicking was very irregular, so not like something catching in the spokes.
I got off the bike & span the wheel - silence, it rotated freely, nothing visibly wrong.
Carried on, and after about a mile the noise stopped in the space of a few yards. A couple of miles later it started again. After another mile it stopped & was silent for the rest of the journey.
This morning - same noise from the start, so I turned back & got on one of my other bikes.
Any suggestions? I'll be having it to bits at the weekend, but in the mean time....
Cheers
Chris
