The long-awaited Brim Brothers Zone DPMX, a power meter that clips onto your shoes and measures power from the cleat, has now hit Kickstarter where it has smashed past its €100,000 target with €175, 443, with 19 days to go.
The Zone DPMX is touted as the first wearable power meter. It’s been in development for several years, road.cc has written a handful of articles charting its slow march towards production. But it seems the Ireland-based company has worked through all the development gremlins and got everything finalised. Delivery is expected in May.
The bad news. The Zone DPMX only works with Speedplay Zero pedals. It uses a special plate that is sandwiched between the sole of the shoe and the cleat (in place of the usual three-bolt adapter). The company says it’s as easy as installing regular new cleats.
This means the system measures power at the point where the power is transferred to the bike. The sensors in the cleat measure the force between the shoe and pedal, and the pod measures motion, and takes all the data and transmits it to a compatible head unit.
It uses ANT+ so it's compatible with a wide range of computers. Battery life is a claimed 15 hours with a 2-hour charge time, and it’s claimed to be IP67 water resistance. Power accuracy is 2%, about the same claim that most power meter manufacturers make. Each pod and sensor plate adds 44g to each shoe.
The company has got a Kickstarter campaign underway and it has already smashed its €100,000 target by some margin. There will be two versions, Zone DPMX Single (left-only) and Zone DPMX Dual (dual-leg) costing €440 and €880 respectively (or €390 and €780 through Kickstarter at the moment. The left-only version is a very competitive price, one of the most affordable power meters on the market at the moment.
The bePRO pedal-based power meter is the one of the cheapest options we've written about recently. It costs £347, and do you get a set of pedals.
Here's a demonstration of the power meter in use.
The power meter market has really got quite exciting over the last couple of years, and it’s one of the most rapidly evolving areas of technology in cycling. From the days when the SRM was the only serious option, there are many good products from Garmin, Powertap, Stages, Pioneer, 4iii, Quarq and others. And there are rumours that Shimano is set to unveil a power meter later this year.

The disadvantage to the Brim Brothers offering is that you obviously have to be a Speedplay fan. The advantage is that you can swap between different bikes easily, provided they each have Speedplay pedals installed. There’s also no removal of cranks needed and you can use your preferred chainset.
This widening choice not only offers different ways of measuring power (hubs, cranks or pedals) but it’s slowly driving down the price. It might not be long before all performance road bikes come as standard with integrated power meters.

Interesting to see how the power meter thing is playing out. Cleat-based metering seems like a great idea if you have multiple bikes and only one pair of shoes. It's a little less clear when you get into multiple shoe/multiple bike teritory but I'm inclined to think that pedal-based solutions seem the most convenient overall in these situations.
Warren, we received your email on 14th February and I replied within a few hours addressing all your questions directly and fully. It seems that email went astray somewhere, so I have resent it. Please contact me directly on barry at brimbrothers.com if you don’t receive it or if you have any further questions.
Anyone who has questions or comments is also invited to email me directly at that address.

If you were on the waiting list, then you got advance notification of the Kickstarter campaign. They've added another kickstarter production run, and there's still units available, so you are able to place an order at the discounted Kickstarter price. If you wish.
Kickstarter route comes with fewer protections than a normal consumer sale though, of course.
Although to be fair it has been a day or two since it was posted. Stick it on when Ray's next post appears

So their only benefit is you can wear them? They're not especially cheap, particularly when you factor in having to buy new pedals. The benefit of wearing them is so you can use various bikes...as long as you have Speedplays on them all. Not for me, I'm afraid.
Good luck to them, though, as the more choice on the market, the cheaper they will become eventually.
Very annoyed and fed up with Brim Brothers. Signed up over a year ago to purchase their power meter. They kept saying it was coming and that we would be supplied in order of our reservation number. Then last week they decided to turn against all of us that had waited and supported them ; they exclusively put it on Kickstarter. By the time I read the e-mail all the May stock had gone, then I spotted they don't deliver on Kickstarter to Japan where I currently live. So my chance of getting it in the next 10 months is zero.
I even wrote to them to ask if they could help. Not a single reply. So if they can't even be bothered to reply to an email asking to buy the item, you can only imagine how bad their customer service is going to be if something goes wrong.....
This
They have been very clear with potential customers for quite some time that those on the waiting list would be given priority.
To then (with no notice) start a kickstarter campaign and leave these long standing supporters in the dark is absolutely terrible customer service.
If they had sent all on their email list a message to the effect of "Due to funding shortfalls, we have had to resort to Kickstarter... please find our campaign here... sorry etc etc" then I could understand it.
As it stands though, this early red flag on etiquette towards customers is enough for me to look elsewhere.
if you feel that aggrieved then head over to the article on dcrainmaker as Barry Brim has been quite good about responding to queries on that thread.
It would be good to see his response to your affliction
I exchanged e-mails with dcrainmaker (very good of him to respond so quickly to me) last week. He'd had the conversation with Brim Brothers before talking to me and wasn't aware at the time of the issues I mentioned. He is now aware and will hopefully discuss.
I'll also add the above post to the dcrainmaker post to see if Barry replies there.
