Following years of teasing a shoe-based power meter, Brim Brothers has announced that its Zone DPMX is ready for production with delivery expected in May. There are two versions on offer, a dual-leg and a left-only.
The Brim Brothers Zone DPMX is set to be the first wearable power meter to market. Spanish shoe company ‘Luck’ did previously reveal its in-built shoe power meter, but has not yet released it for sale.
Said to work with any three-bolt road shoe and Speedplay Zero pedal, the Zone DPMX works by placing a force plate in place of the usual Speedplay three- to four-hole cleat adaptor plate. This measuring plate is linked to a sensor/ANT+ transmitter on top of the shoe.

While it can currently be pre-ordered even cheaper through KickStarter, the Zone DPMX Dual is set to retail at a competitive €880 (Approx $995 / £690 / AU$1,400). The left-only version costs exactly half that (€440), which should make it one of the cheapest options available.
- Weight: 44g per shoe
- Price: €880 for the dual version, €440 for left-only
- Expected availability: May 2016
- Connectivity: ANT+
- Battery type: Rechargeable Lithium Ion
- Water protection: IP67 (30mins at 1m)
- Battery life: 15 hours
- Power accuracy: 2%
- Cadence range: 25 – 180rpm
- Compatible pedal system: Speedplay Zero (not included)
- Compatible shoes: Three-bolt road (minimum one strap needed)
The key advantage to a shoe-based power meter is in its simple multiple-bike switching and guaranteed compatibility. While the Zone DPMX is currently limited to just Speedplay pedals, it does solve common issues in crank, bottom bracket and frame compatibility.
Limited to road shoes and Speedplay Zero pedals, this is certainly a product for road-based riding only. Data hungry cross and mountain bikers should most definitely be looking elsewhere.
