I would like to ask you two questions about the On-One Monocoque Tapered Carbon Fork. First, what is the maximum height of spacers that is allowed to use, between the top of the headset and the bottom of the stem? I'm asking it because some of the documents and videos that I found mention this as a possible limitation (or a kind of take care of) and suggest to check the manufacturer's specifications.
What is the biggest disc size that is allowed to be used on this fork?

Thanks a lot for your help!
