Six years of development, and a crowdfunding target smashed in less than 24 hours. That’s the story behind the Brim Brothers Zone DPMX power meter, the world’s first wearable power meter, which measures power and cadence by attaching to your shoes and cleats.

>>> Power meters: everything you need to know

The system, which must be the most portable power meter on the market, uses two seperate sensors to measure power and cadence. The power sensor is located between your cleat and your sole (although unfortunately it’s only compatible with Speedplay cleats and pedals at the moment), while the cadence sensor is attached to one of the straps on your shoe, and it will work as either a single-sided or dual-sided system.

However if you’re after accuracy over convenience then there be better options out there, with Brim Brothers giving a claimed accuracy of ±2 per cent, so not quite up there with the admittedly much more expensive options from SRM and Verve. Battery life could also be a bit of an issue, with a claimed life of 15 hours at 20ºC, so you’re probably going to have to recharge them every week or so.

>>> Spotted! Is this the new Shimano power meter?

As well as power and cadence, the Brim Brothers Zone DPMX will also measure torque efficiency and pedal smoothness, bringing it up to the standards of much more expensive power meters, while the dual-sided version will also measure your left/right balance.

In terms of pricing, the single-sided Brim Brothers Zone DPMX Single is currently available on Kickstarter for €390, approximately £300 (plus tax and shipping), while the dual-sided option is €780, or £605, making this one of the most affordable power meters on the market.

  • 4iiii’s is much better value, accurate and already available.

    so change all your pedals if u don’t run speed play plus the price of the cleats, i don’t think this can be labeled a cheap system

    Interesting, so basically a pressure plate. But how do they deal with the torsional forces generated throughout the pedal on the plate itself? Sounds like an algorithm based product to iron that out…?

    Does that pressure plate raise the stack height of the shoe above the pedal spindle?

  • ummm…

    im not sure i want to know that much about my performances.

    But why have they felt the need to go on Kickstarter… you only need to look at the failed Zano drone to realise this looks like a bit of a cop out. It seems very much like a way to allow them to raise funds and take orders, but treat people as investors not customers if it all goes wrong or something else breaks.
    Surely with the time they have put into getting it right, if they believe they have fixed the issues, they could sell direct with a longer lead time for delivery….?
