    Popping from my handlebars.

    I'm getting a worrisome sound from my handlebars. Whenever I'm out of the saddle, sprinting or climbing, I hear a popping noise from my handle bars. I tried tightening the stem, but that didn't seem to help. Any ideas?

    The bike is a Motobecane, purchased from an online dealer. The stem is a one piece aluminum deal. The brifters are sora.

    I'm also hearing a clicking sounds, which is coming from the front end of the bike somwhere. Doesn't seem to be cables knocking and there doesn't seem to be anything loose on the front brake or anything.

    Thanks in advance!

    Sometimes that "popping" noise is just from the bar tape bending and crinkling as you flex the handlebars. However, it's never a good idea to ignore a potential problem with the handlebars, stem, or fork, so you should check for cracks near where you think the sound is coming from.

    Another possibility is that your headset is dirty and the bearings are making a crackling noise when they're under stress. Have you serviced your headset recently? Have you been riding in rain and mud a lot?

    I don't think its the tap, its a pretty significant noise. I haven't serviced the headset since I got it. That might be something to take a look at. I've ridden in light rain once, all my other rides have been dry.

    Thanks.

    Well... the headset is an unlikely problem on a new bike, provided that it is well sealed and was properly adjusted by the mechanic who originally assembled it. Normally it takes me months or more of riding in crummy conditions to notice any roughness or noise from the headset.

    Then again, if you got it from a discount internet place like bikesdirect, they might not have done such a good job installing/adjusting the headset. Check out parktool.com/repairhelp for headset adjustment/overhaul info.

    My guess would be the handlebar clamp on the stem.

    Take it off, clean it really well, put it back again.
