    Lightbulb mystery ticking noise on road wheel solved

    While out doing the Toutant-Bauregard Thursday evening ride, I had this ticking noise upon each revolution from my rear wheel. It had us all stumped. It didn't matter if I was pedaling or not, there was nothing stuck in the tire, the spokes seemed OK, it went away if I spun the wheel while not sitting on the bike meaning it only occurred when I was sitting on it. Big John (Sleeper) was there and thought it might be a spoke. That answer made the most sense, but they seemed OK.

    Here's a clue: just before the ride I had discovered I had a flat on that wheel, and put in a new tube made by Vittoria I had never used before that has a slick stem with no threads for a nut. I have high-profile Rolf Vector Comp rims.

    I took the bike to Bike Heaven the next day. James rode it around the parking lot and couldn't find anything wrong, but did hear the noise. He said, all I hear is this - pointing to the stem. I tapped on it, and discovered it makes a ticking noise if moved a mm either way when contacting the rim.

    Mystery solved. To silence the noise, you can put one wrap of electric tape around the base of the stem before putting it in.

    So in other words.

    If you wrap it before you put it in, no problems down the road. Got it.
