I got the ABEC adapters so I could put cloudwheels on my BC2 DD. Very easy process to swap them. No issues.
Changing wheels to cloudwheels from the 115mm rubbers which came with the board had to swap as well the Adapters, easy swap, great add on for my board, now can change between Kegel & Abec core wheels easily.
I got the board with kegel adapters the initial setup with the 115 rubbers, but when i got the cloudwheels had to swap for the abec adapters as well, it was a bit over tighten with the screws, but after using some fast release wd40 it took a while and i could swap them. the customer support was great helping me through the process all the way so good word for them as well. just to know what i didnt abec adpaters fits as well for cloudwheels, so all cool, thank again onsra california!
