How have you found them and any alternative suggestions

I've got 4 and one Acros one.

I've had one Hope fail at only 7 months and about 700 miles. the rest are getting on for over a 1000 now.

The Acros is well over 2800 miles and is still smoother than the Hopes.

That's where my money would go.

i have an acros ceremic on my demo9 for over 2 yrs. fit and forget 🙂

I've the Hope one, its done 12 months and circa 2k miles, greased once when I stripped my bike down after last winter.

No probs.

put one on my yeti last month and all good so far.

I replaced a standard shimano with hope ceramic cos it was too good a price not to (about £73 iirc) about 6 months ago. no probs so far- won't be sure it was worth it till done a winter though
