I recent purchased the Elite Qubo Digital Smart B+ for the smart trainer aspect to use with Zwift. My rollers are fine for the workouts, I’m interested in the road feel and after a couple of rides with the Qubo, it delivers. At the price ($450 US dollars) it has exceeded my expectations.
I have ride with a Powertap C1 power meter and comparing it with the Qubo, the Qubo is off about 20w-30w.
Elite has a procedure to calibrate the Qubo, but you need a power meter to get the numbers to enter.
I’ll be doing that here in the next couple of days using Elite’s troubleshooting guide.
Since I’m using a power meter with Zwift already, I’m not too worried about power metering with the Qubo and the smart feature works well.
