Josh is all over it. The Core is a good choice of many. It does have a cadence sensor built inside. I think the core gradient measures up to 10% while the Kickr might be over 20%. With each new model, it changes so I can't keep up with it. This means your legs will feel the climbs more with the Kickr but not the watts you need to get up the hill on the really steep stuff (hint, no one rides there)? I don't know how that works. The math boys seem to understand but I think it's voo-d0. The funny part about the gradient is the vast majority of high-end purchasers get the most gradient they can buy and then immediately use a little slider called a difficulty slider to reduce the gradient. Just saying?? If you plan to buy a laptop for Zwift the ATV is an option you should at least look into first. Lots of happy ATV users out there. I don't think this will help you with trainer road though. As far as size screens--You can run it off a smartphone up to the largest big screen. The best experience will be the biggest screen. Lots of difference. Let your budget and location decide.
