On paper the Saris H4 Smart Trainer is a step-up in compatibility and power accuracy for the flagship smart trainer from Saris. Unfortunately the review unit sent over failed both the 12 speed compatibility test and did not meet the claimed power accuracy specifications. In late 2022 this is not the kind of review that I expected to be publishing…. but here we are. 🤦🏻♂️
