The Magnetless Speed or Cadence Sensor from PowerTap

[BicyclePower]

Madison-based cycling power meter manufacturer, PowerTap, recently introduced the Magnetless Speed or Cadence Sensor to the masses.

This dual-band sensor is named for its central feature: the absence of a magnet. Leaving archaic data collection behind, the Magnetless Speed or Cadence sensor taps into the advances of in accelerometer technologies to acquire ride data. 

Freeing itself from the constrains of a corresponding magnet, this sensor can be placed in three different locations on the bike: the non-drive crank arm (cadence), the rear hub or the front hub (speed). Its low profile design eliminates clearance concerns, and can easily be programmed for either speed or cadence. Plus, it’s the perfect training tool to measure data indoors with your favorite virtual training application.

Want to change from speed to cadence or vice versa? This sensor can do that too.

Take a look at the video below to see what's in the box, how to program - or change - the sensor for speed or cadence, along with how to install it on your bike.

Yes admittedly some rear hub brands with a narrow centre will not be compatible however having checked on the majority of hubs we have in our workshop (and those non PowerTap hubs) the PowerTap speed or cadence sensor seems to be compatible with most hubs.

 

The exact length of the unit is 47mm so anything longer than that the sensor will be OK.

 

Each brand has their pro's and con's. PowerTap slightly thinner but longer.
