anyone use a hope ceramic bb or similar, ceramic jockey wheels?
i’m interested in lifespan over normal units
sramxx has ceramic, xo has normal

I use Hope ceramic BBs in two bikes.
I thought £80 was a bit steep, but they have easily outlasted 4 Race Face BBs at £25 each, so are worth the investment.

I used FSA ceramic jockey wheels in a Rohloff tensioner. I’ve gone to hardtail now with sliding drop outs or EBB, so don’t need a tensioner any more, but they seemed to be lasting well when I had them.
