Hi all, I have a kickr snap coming in the next few days and have a couple of queries: I'm wanting to share it with my other half and can't seem to find the answers: The Bkool trainer I had before had a special skewer, but I can't find an extra one for the Snap. Is there any particular one to get that fits properly? Also, how does the thing handle multiple users from a software and calibration perspective? I gather a brake strength is set depending on spin down results, but is this stored in the app or on the actual device? I'm thinking an iPad each, with our own wahoo apps and advanced spin down. Or will we have to share an iPad and do the advanced spin down every time we switch bike? Thanks!
