My bottom bracket has started creaking.
Yesterday me and the horde of children I claim to have went for a ride. During the ride I had cause to stop to adjust no1 child's bike, while No.3 held mine.
10sec later my bike was on its side. It fell on the left side, the right side BB bearing is now creaking under high pressure. I'd like to say that's all the time, but it would be a lie. Tested by replacing the pedals, and pedalling one footed for a while. Peddling with left foot only doesn't creak.
The last BB I replace was circa 1988 with shells and bearings.
While I'm able to do most things to bikes, I'm aware that these modernist BB's are sealed units. There are no cotter pins either
2007 (approx) Ultregra BB. Can I sensibly get it out myself? And if so is it really unserviceable? There are grey rings stating "Do not disassemble" But that's never stopped me before.
Pickky of left side attached.
Edited for spelling and other weirdness.
