The tiny unit fits onto your shoe and does the job at a power meter at a much smaller price. It's raising lots of money on the online crowd-fund site Kickstarter.
Here’s something that’s been overdue for a long time; a simpler and cheaper alternative to the big brand power meters already on the market.
The Brim Brothers Zone DPMX power meter is currently raising capital on crowdfunding site Kickstarter.
At the time of writing it had bagged just over €160,000 from 248 investors in one day despite an initial goal of just €100,000. And it still has 27 days to run.
The new power meters are pretty simple. They attach to your shoes and cleats and from those generate all the readings that more expensive power meters do.
The company behind the new product, Brim Brothers, is based in Dublin and headed by Dubliner Barry Redmond who rides with the Orwell Wheelers club in the city.

The new system measures power and cadence using sensors in those pieces of kit that fix to cycling shoes and cleats - see photos and video below.
The sensor that picks up power is located between the cleat and the sole of your shoe – no surprises there perhaps.
And the cadence is picked up by sensors in the straps on your shoes; see photos and video below.
Redmond’s kit also measures torque efficiency and pedal smoothness as well as left-right balance.
The company claims the battery will last for 15 hours at 20ºC and claims accuracy within a margin of two per cent.

That means it’s not as accurate as the bigger brands but for many that kind of margin will be fine.
And the price is also very much smaller that more established brands. A unit for one shoe is €440.
Brim Brothers claims each unit weighs just 44gm. It also says it is “completely sealed to take any conditions”.
The power meter will be visible on top of the shoe and also by the strap attaching this part to the underside plate.
The fixture under the shoe that takes the readings converted to the all important data.
It looks like a game changer if it proves robust in all conditions. The black item on the right is the unit you clip the kit into when it needs to be charged.
