We got one of Hope's ﬁrst production ceramic bottom brackets over a year ago. The great news is that after all that time it’s still going strong, despite constant use and absolutely no attention.
We did hear of one over in the Pennines that needed a clean-up after a month, but that’s been ﬁne ever since. It looks as though their unique labyrinth seals, direct mount INA bearings and alloy sleeved design work.
The downside? Hope's bottom bracket is pretty expensive at almost £100 and slightly heavier than other ceramic sets.
