I’ve got a CK on my Obed and a Hope on my RC200.
I can’t tell any difference in quality to be honest and would probably stick with Hope in future.
Both have been reliable, trouble free and what you could call fit and forget parts.
I have had cause to have to contact Hope for spares, albeit for my brakes; and they were really great to deal with and got a part to me in 24hrs.
I haven’t had to contact CK for anything, but I would imagine that they wouldn’t be as easy to deal with as Hope; if only for the distance and time difference.
