Whats the absolute cheapest way to set up Zwift without sacrificing performance - and I dont mean those ridiculous DIY hacks that involve duct taping an iPhone to your bike, I mean actual, legitimate hardware. Can you really get by without a dedicated trainer, or is that just going to end in disaster? And whats the real difference between ANT+ and Bluetooth - is ANT+ worth the extra hassle and cost, or are the roadies just drinking the Kool-Aid? Whats the bare minimum hardware spec required to run Zwift smoothly, and can you get away with using a laptop from the Stone Age, or do you need some sort of gaming-grade behemoth? And dont even get me started on the whole smart trainer vs dumb trainer debate - are smart trainers just a bunch of overpriced nonsense, or do they actually offer some tangible benefits?
