by Andrea B. on 19.04.2022 item: black/14 teeth (guide pulley), 16 teeth (tension pulley)

Really disappointed on how Ceramic pulleys spins. Always show on C-bear Instagram videos a Full ceramic spin that is for lots of seconds. I thought ceramic was similar, than when I received at home and did a test with a finger I was totally disappointed because is almost similar to a standard shomano pulley. I didn't mount on my bike yet. I sent lots of messages to C.bear explaining my disappoint and the result is buy full ceramic or the only statement from them was: "try to believe"
I think I will ask refund and don't use them at all. First time that I was thinking to chage from Ceramicspeed to spend less money, but I would say: "who spend less...will spend more"
