InfoCrank Support

Accelerometers and gyros are improving, but in our view their cadence readings are not yet accurate enough to calculate overall power to the precision we require.

Verve continues to design and test alternative options to cadence magnets that would further simplify InfoCrank installation, and we hope to have a solution as accurate as magnets in the future.

While the idea of magnets sounds a bit old fashioned these days, Verve says that because road surfaces are never perfectly smooth, the accelerometer’s readings are easily affected, making it difficult to actually identify a cadence trigger. 

I'll also quote your comment to BikeRadar:

I see the new firmware update removes the need for magnets, but unless I'm mistaken it's impossible to deliver me a new accelerometer via a software update. Sadly I can only conclude then that your precision requirements have changed?

Timo - you're right, we are not delivering an accelerometer via a software update. However you're not right that our precision requirements have changed. With our new firmware, we've been able to improve our cadence readings above and beyond cadence magnets, which to date were the most accurate form of measuring cadence on a bike. But we've done this without a hardware change of gyros or accelerometers. Pretty exciting!
