Resistance gauge for Sunny Heath SF-B1002 spin bike. Measures the movement of the leather friction pad. Ranges from 0 to 100 in 10 percent increments to work with Peloton workouts. Fully assembled ready to install with one (1) zip-tie (no tools required). Instructions & video link included. I have tried my best to build a gauge that is functional & durable. This bike with it’s leather friction based resistance was very difficult to gauge, since there is only about 1/4 inch of movement of the pad. I designed & redesigned the gauge about 7 times for to make it easy to install & use, while being as accurate as possible. I only have a 1/4 to work with. I include multiple stickers to adjust to any bike variations. Sunny Sf-B1002 Resistance Gauge
