SRM X Energy MTB Energy Meter Very first Appear: A Turning Point for SRM?



For the initially time in around ever, I’m essentially excited about an SRM solution and exactly where the business is heading. Right here, appropriate off the top rated of this post without having a wordy intro, in a mere 3 bullets I’ll clarify why:

1) It is essentially priced appropriately and competitively in the marketplace
two) It does not involve Look’s engineering operate, for which the SRM EXAKT pedals have been primarily based on (to substantial fault)
three) It is special in the marketplace and could be the initially shipping solution in the category (MTB energy meter pedals)

And that is about it. That is roughly all you will need to know.

Oh, I guess, I mean…sure…there’s a bit additional. Like specs and stuff I suppose. So let’s speak about these.

The Specs:

The SRM X may perhaps effectively be the initially energy meter pedal for mountain bikers when it gets to marketplace later this year. Although, I suppose that title will rely a bit on no matter if IQ2 can get there initially or not with their altered-course Kickstarter project. But, I’m going to presume SRM will win this battle, if only for the purpose they’ve been actively testing and riding their pedal considering that earlier this year. Plus, energy meter expertise and all that.

But once more, let’s concentrate on some speedy specs initially, considering that that is the superior stuff:

Cost: 1,000EUR
Availability: Dec 2019ish
Pedal Compatibility: SPD (MTB)
Stated Accuracy: +/- 1%
Protocols: Dual ANT+ &amp Bluetooth Wise
Battery Life: 80 hours
Weight: 165g per pedal
Appear Involved: Nope de Nope.

Now as I alluded to earlier and straight in the line above, this pedal is an SRM-only venture. Which means that the SRM EXAKT pedal that came out final summer season was in partnership with Appear. The challenge there was that they adopted Look’s technique of installation and calibration, which needed particular tools, boatloads of finicky time, and sufficient patience to not via throw the bike at incoming visitors.

But that is gone with the mountain bike variant. SRM has transitioned to an set up course of action that mirrors typical pedal: Crank them on…and completed. Just like Favero Assioma, Garmin Vector, and the PowerTap pedals. No fancy tools, no funky apps, practically nothing. Just twist on.  They’re capable to do that by adding in an accelerometer and gyro, which also lets them ditch the magnets of the SRM EXAKT pedal (magnets have been utilised to ascertain rotation of the spindle, and hence utilised for cadence and in the end energy output).


Subsequent, just like the SRM EXAKT pedals it include active temperature compensation in it (in truth, the newer crankset SRM Origin units lastly also now have temperature compensation in them, alongside dual ANT+/BLE). The value of that is realistically much less meaningful in mountain biking exactly where you are normally stopping and beginning pedal, whereas in road cycling it is a enormous deal for any person that is completed extended climbs up mountain passes exactly where the temperature shifts drastically and you do not cease pedaling.

From a battery standpoint, the pedals are slated for 80 hours, and use a magnetic charging adapter to charge every pedal individually. As opposed to the Precise pedals, I’m told they’ll essentially involve two of the charging adapters in the box. So you know, you can essentially charge your two pedals at the very same time.


Like SRM’s head units, it’ll come in a slate of colors. I’m told the very same list of colors as the SRM PC8 is out there in, which…is a lot of colors. The purpose is additional simplistic although: The pedal spindle conveniently (with a tool) slides out of the pedal physique. The complete point is self-contained in the spindle: Battery, communications electronics, strain gauges, modest villagers, all the things. That signifies you can get distinctive colored pedal bodies and swap about. So maybe you have two drastically distinctive colour-schemed mountain bikes, this solves any sort of style faux-pas.


The complete point is housed inside that stainless steel tube there, which SRM says they’ve gone via dozens of test variants on to come across just the appropriate components and building that is capable to withstand the horrible life that is getting a mountain bike pedal. The company’s engineers have been riding the pedals considering that earlier this year out on true trails with true mountain bikes.

Note that it is probably we’re going to see a pile of SPD energy meter pedals, as my understanding from many people today is that Shimano’s SPD patent expired earlier this year. Some thing that Google appears to confirm.

Like with the SRM’s road pedals, this will transmit ANT+ &amp Bluetooth Wise, and energy balance (left/appropriate balance) for each. It will not do the not too long ago opened up Cycling Dynamics, but I suspect there’s much less interest in the mountain bike segment anyway for that.


Now of course, I haven’t tested these pedals however. Be it on a trainer or out in the wilds of rough terrain and hitting against rocks, trees and modest gnomes. That’ll come at some point down the road, probably towards the finish of the year when they’re set to start off shipping.  So issues could go horribly incorrect when I essentially attempt and use them and examine them to other energy meters on the very same bike.

The shipping strategy sounds like it is December, but I got a bit of a feeling from speaking to many people today at SRM that may possibly also be additional like a January or so. I do not assume there’s an appreciable distinction involving these two for the sport of mountain biking in most snowy markets.



As I stated at the starting – I’m essentially reasonably excited this could be a turning point solution for SRM. By and significant the business hasn’t been innovating in the final handful of years, and as a outcome, has observed their marketplace share dwindle down to practically practically nothing in terms of % of new energy meter sales – in spite of possessing enormous brand recognition in the sport. That is largely been a function of cost, but also technologically also.

Nonetheless, the SRM X appears to be on the appropriate path towards redemption. From a initially appear standpoint they’ve gotten rid of the components of the technologies that have been weighing down the solution, though focusing on simplicity in setup. The capability to swap pedal bodies simple is attractive from a breakage standpoint but also just from a cosmetic standpoint – plus, no one else has that. But of course, the biggie on the ‘nobody else has’ front is merely a mountain bike pedal primarily based energy meter. As noted earlier on, IQ2 has shown one particular on their new directions campaign, but we do not know how true that is, nor exactly where they stand in solution improvement and accuracy out on the trails.

But lastly – there’s that cost. Suitable now at 1,000EUR (assuming VAT-inclusive), it is competitive on the European side for positive. If they can match for parity on the USD side ($1,000USD), that would be hugely competitive and inline with road-bike energy meter pedals (Vector three is at $999, although the PowerTap P2 and Favero Assioma pedals are reduced priced). Provided that SRM stands to be the initially to marketplace with this, the slight premium more than PowerTap and Favero would be logical. I worry any greater although and they’re probably to drop interest from quite a few riders. Absolutely there’s an element of mental cost-break math, and $999 is a effectively established cost point break.

With that – I appear forward to testing these out when the occasions comes, hopefully later this year. Thanks for reading!
