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!

Sure can. On my touring trip in 2005 I had a problem spoke that kept coming loose. Along the Columbia River where there wasn't much traffic I could here a faint click that drove me crazy until I got found the loose spoke. The reason for it is that the spoke doesn't "fill" the spoke hole at the rim. The holes at the rim are 2.3mm and the spoke is 2.0 mm. If the spoke is loose, it can move in the hole. Eventually this will cause fatique of the spoke and failure. It's the main reason I use DT Alpine spokes. They are 2.3mm at the head and fill the hole at the hub. No room for movement and less likelyhood of spoke failure, especially for wheels that have to carry heavy loads.

As for the presta retaining nut, I've tried going without them but I just can't. Everytime the wheel goes around, I think of that presta valve just waiting to pop out and fly up and poke my eye out and I have to stop and put the nut back on! My inner mother feels safer then
