Any real difference between the two.?

in use, no difference at all, my ceramic, seized up after 6 months, sent it back to hope, who replaced bearing, and suggested i had put too much preload on bearing(i hadnt), since then 8 months they have been fine

I have had a stainless for about 7 months and its great! Just bought another for the new build – not a part worth scrimping on IMHO.

I got the Stainless version, 4months later a little bit of play which hasn't progressed much more after a further 2 months of riding, eventually gonna send it back after this weekends ride! Although am confident will be sorted within time for my next ride thanks to hopes great customer service!

Ceramic you save like 3grams! Look after your grams and the pounds will look after themselves 😉
