Gentlemen, thank you for the recommendation. The Tong-Shen looks like a true torque sensing system for the active cyclist. I'm reading that the power assist tapers off as the cadence increases above 90 rpm, it this accurate? It's not a deal breaker, but I'm interested to know the specifics. Also, at what speed does the power assist begin to taper.
Thanks'
