Tried posting in General but didn't get much response so I figured I would try here....

Its summer here atm, and cycling outdoors is still fine but during the day it can reach 34C with +90% humidity so I tend only to cycle early morning if I can wake up or late afternoon/evening.

I'm thinking of an indoor trainer, that is Zwift compatible, maybe the Cycleops Fluid 2.....

A few questions to those of you who do train indoors:

1) Buy a cheap Smart trainer vs 'standard' or Fluid 2 trainer?......the obvious for a Smart trainer is the resistance changes according to Zwift terrain, anyone use a 'cheaper' smart before?

2) Do I need a trainer tire? if so, how do you guys go about it? buy cheap 2nd wheel/rim and install with trainer tire?
or you change tires each time you use the trainer?
Also, my bike has disc brakes, is it possible to use a standard rim-brake wheel on it since I don't need a rear brake on a trainer.

3) What other recommendation for trainer? Tacx Neo is out of the question, its more expensive than my bike

thanks a lot
