The Dreaded Creak

[roubaixtuesday]

How many miles on the BB?

Since new, nearly 10 years but pretty low mileage, low 1000s

You ever prized the seal off and added fresh grease? Might just hsve very little left.

Please check the cranks for hairline cracks, in particular around the pedal threads.

It would be nice if you could point me to the post where that specific "crank hairline cracks" already were mentioned. Many, many thanks in advance!
Despite reading the thread again I couldn't find it.

Perhaps I need new glasses...

So, have you removed the BB cups, cleaned and re-greased the lot yet ?

Gimme a chance! Will be trying to find time for that over the weekend. Big ride planned Saturday.

Yes, checked that and greased the contact surfaces (which IME can make a huge difference)

One side of the BB was slightly loose.

Removed, regreased threads, problem solved.

Thanks all for suggestions.

Hurrah !

IME the BB is often the culprit.

Despite internet folklore where everything is checked and it turns to be the shoes or saddle etc - never rule out the BB

In several decades of creak finding, this is the very first BB for me, though I did have a loose eccentric shell once, so maybe two.

*Much* more common IME are saddle rails, QR fixings, seatpost fixings, pedal bearings, chainring bolts, wheel spokes, and attached bits like racks etc. I've even had three cracked frames causing creaks.

Just my experience, not saying it's generally the case. Maybe we should do a poll.

told you so!
