Noise diagnosis?

[Baka Dasai]

I have a squelch/chirp/creak sound coming from approximately the rear
hub area. It's there when both coasting or pedaling, and its frequency
is in proportion to the speed of travel. However it does not sound when
I'm walking alongside the bike, or if I spin the rear wheel while it is
off the ground.

An ideas? The rear hub?

What was I thinking?

Spoke reflectors? Spoke protector? Valve nut? Noisy joint where the rim's
put together? Just a few things that people don't always think of.

Try braking the rear wheel and putting some force on the pedals while
it's off the ground (I'll leave it up to you how to do that). That way
it simulates a "load" on the drivetrain without full rider weight on
the bike and wheels.
Or maybe you could swap a wheel with a buddy for a test?
Probably helps to narrow it down.

Loose strokes, buckled wheel...?

Seat rail, skewer lever, spoke nipple, spoke crossing, valve nut, bearing.
Pebble imbedded in tread.

One possibility: Spoke creak. Try a small drop of oil on each spoke
nipple where it comes through the rim. Don't overdo this; you don't
want the oil to soak through the tape inside.

This article has been a help to me to solve many noise issues.
It helps to know the brand of hub too, as some are known for these
kinds of issues.

During winter here, I hear that sound very often. "Cupped" snow tires ... on a
junky pickup-truck, usually.
