I have an annoying wheel problem. The wheel tends to click (a dull click - sort of a quiet tok, tok, tok noise) at each revolution. This only happens when the bike is loaded (i.e. not when I'm free-spinning the wheels), and only at slow or moderate speeds - not once I'm travelling over 25kmph (15 mph).
I've been looking at everything to work out what the problem is. The wheels are relatively new (only a thousand or so kilometers on them) and it has only been happening the last couple of hundred kilometers.
The wheels are hand-built, deore hubs, 36 dt spokes and sun cr18 rims.
Feeling the spoke tension by hand, they seem slightly looser than on my other wheels, but not too much so.
The only other thing I can think of is one of those little rubber bits poking out of the tyres hitting the fenders at each revolution. I have removed the wheels and put the bike inside a car a few times, so the fenders aren't quite true.
Would tensioning the spokes and retruing the wheel fix this problem, or is there something else obvious I am missing?
Thanks in advance!
