  1. I bought a new bike a few weeks back and whilst riding it
    today I noticed a very unusual noise from the rear of the
    bike. After some investigation, I could reproduce the noise
    by pushing the bike along whilst leaning down hard on the
    saddle. As the wheel rotated slowly it sounded like the
    spokes were making a pinging noise, one after the other
    - a bit like as if you flicked them with your fingernail. If
    I took the downward pressure off the saddle the noise
    disappeared.

    I'm pretty sure this is a new phenomenon. I tapped each of
    the spokes and the tensions seemed consistent. Is this a
    normal part of a new bike 'bedding down' because I've not
    experienced it before? Could the hot weather have had
    anything to do with it? I'll ask my LBS about it
    if/when I take the bike in for its free six week service,
    but can anyone advise what the cause may be, and how I
    could fix this myself in the meantime?

    Thanks, Paul

    I've spent most of my money on mountain biking and windsurfing.
    The rest I've just wasted.

    I've spent most of my money on mountain biking and
    windsurfing. The rest I've just wasted.

    Thanks. It would appear the most likely candidates are:

    1. The spokes weren't sufficiently stress relieved, or
    2. The spokes are working a little loose

    Unfortunately my LBS isn't actually very local so I will
    have to plan a visit in advance. Am I likely to damage the
    wheel by continuing to ride on it in the meantime? My home-
    grown temporary remedy would be to squeeze the spokes in
    sets of four (as described in the above link), and then
    tighten them all by a 1/4 turn. Or should I just take it in
    for its 100 mile service ASAP...?

    Paul.

    Probably not stress relieved. I'd just make sure that
    none of them are loose and forget about it until the 100
    mile mark.

    Use the sound method to judge which one's may be loose..
    Tighten to remove the dull thud sound. Leave the rest alone.

    Thanks DTW, this is all useful knowledge 🙂
