Hi! What do you think about ThinkRide X3 smart trainer? For now is the chepest smart trainer, with power-in, cadence and speed sensors incoroprate, perfect for low buget zwifting.
Consider the Kurt Kinetic Road Machine with InRide Sensor (v2). These are available on the second-hand market, and provide VERY accurate power metrics.
Unfortunately, in mu country(SE-Europe), the shipping price for the product is more than the product itself, or almost,overall, i reach higer prices
