After six years of development, Brim Brothers’ long-awaited wearable, cleat-based power meter launched on Kickstarter, quickly reaching more than 30 percent of its 100,000 euro goal.

The Zone DPMX measures power using a small plate placed between the sole of a cycling shoe and the cleat of a Speedplay pedal, replacing the four-hole to three-hole converter required to use Speedplays with three-hole shoes. A pod containing accelerometers and other gadgetry sits on top of the shoe, sending information via ANT+ to any compatible cycling computer. The system is as mobile as a pair of shoes, completely self-contained, waterproof, and, as of press time, is among the least-expensive direct-measurement power meter available.

This is not the first time Brim has launched the Zone. A promised 2014 production run and planned availability in 2015 were delayed, though the company has had working prototypes for years. The price then was $1,000, but has since dropped considerably. The company is now promising delivery to Kickstarter funders in three months’ time.

Brim Brothers is Kickstarting two models: The Zone DPMX Single, which measures power in only one cleat and will double that measurement, as Stages power meters do, and another two-foot meter called the Zone DPMX Dual, which measures power at both feet.

The Single is available for €390, and the Dual is available for €780.
