A mysterious squeaking noise has started emanating from my new bike (a
Trek Pilot 5.0 - carbon frame and bontrager race wheels). The squeaking
noise seems to come from the rear of the bike and occurs when I'm
riding any faster than about 8mph (becoming more rapid and higher
pitched the faster I go), and continues while I'm freewheeling, so I'm
guessing it's not the pedals, gears, or chain - it'd be great if it was
brake-scrape - but I don't think it is, as the sound persists even
after I've loosened the breaks using the brake quick release - they're
definitely not touching the wheel. I think that only leaves the wheel
itself as a possible source of the noise...
Unfortunately I've only be able to produce the sound while riding the
bike, not while holding the bike and walking/jogging, and not while the
bike is resting upside down with me turning the pedals by hand. I weigh
11st10 so I'm not giving the bike /that/ much grief from sitting on it.
The bike's only two weeks old, so obviously I'll be taking it back to
the place where I bought it for inspection! But can any wise old rider
take a guess at what might be the problem?
best regards,
Roberto
