Review: Rotor 2INpower MTB Crank

Mar 2, 2020 at 8:52
by Zach White  


I’m a mess. A head-to-toe X-ray of my beat-down, middle-aged body would reveal enough metal inside it to look more Wolverine than healthy human, yet I don’t have any special powers that accompany the hardware - unless simply not having to walk with a cane counts. The latest injury, an essential shattering of my left femur thanks to sucking at snowboarding, has been the worst of a half-dozen surgery-worthy injuries, and the closest I’ve come to having to permanently walk with said cane.

It was four months before I was cleared to walk without any type of crutch, and in that time frame, my muscles had atrophied so badly that the plan of throwing the crutches at my doctor’s desk and flipping him off over my shoulder as I skipped out of his office door was forced into plan B, which was to hang on to a cane for a few extra weeks due to the inability to propel forward without low-speed wobbling.

Rotor

Up until this point, things like power meters and heart rate monitors were things I equated to triathletes and the like. Sure, the big names in mountain biking use those gizmos, and more power to them, but I gave up a long time ago at improving my mountain bike mediocrity. That is, until it really sank in just how long of a road to recovery it’d be to get to some level of personal norm on the bike after this injury.

So, while some may look at my lack of true interest in all things electronic bike to review something like Rotor’s 2INpower cranks as a disservice, we viewed it as a perfect opportunity to highlight the opposite end of the performance-enhancement spectrum. Sure, it’s pushing outlier status, but what better way to test a product intended to be a tool for balanced power output than to throw the most lopsided dude in the proverbial office on it.


Rotor’s 2INpower MTB cranks were the first dual-sided mountain bike power meter to hit the market. Ask any coach or Lycra-clad athlete about training and expect to hear all about how power meters are the best way to gauge fitness and use as a more accurate training baseline than heart rate monitors. The 2INpower cranks meter and display that power in the form of watts, and do so in a split format to show just how evenly - or unevenly - each leg is contributing to wattage. More often than not, riders have some level of discrepancy between the power produced in each leg. This doodad is a perfect way to discover and document such variants in simple percentage numbers, and lends itself to help remedy discrepancies, too.

On the elite end of the spectrum, it can be an integral tool at fine-tuning that last little bit of fitness. And, down at the shallow end of the pool where I was crashing Silver Sneaker aquatic yoga classes, knowing just how offset my watts were on each leg helped me form a better game plan with physical therapy, and quite possibly kept such lopsidedness from spreading into other parts of my body. If you’re lucky enough to have never had an issue with, say, your lower back seizing up due to a bad ankle, chances are someone you ride with could blab on and on about it. There will always be exceptions to just about anything I state, but in general, a balanced body is a happy body.



Set Up

When the 2INpower cranks showed up, I wasn't quite sure what to do with them. For starters, I didn't own any type of head unit personally, and basically assumed that there'd be a phone app to use, or maybe Rotor would send a head unit with the cranks.

To clarify, Rotor does have an app, and it's mentioned in the owner's manual that's usually sent with 2INpower cranks, but my demo cranks showed up without standard retail packaging or an owner's manual. When inquiring about what the best option would be to unlock the data from the cranks, Rotor's app wasn't initially mentioned, either. What was conveyed was that there's essentially minimal communication between companies who make power meters and companies who make compatible head units.

As an admittedly clueless person to this kind of tech, it felt like I'd been sent a desktop computer sans keyboard, and without a recommendation of what brand keyboard to use. Rotor simply states the 2INpower cranks need a device that is ANT+ or Bluetooth capable, but beyond that, there is no brand partnership or list of recommended head units.

Because power is measured for each leg, it's easy to spot strength differences.

The first 3rd party head unit acquired was rather buggy with Rotor's product. Rotor pointed to the general disconnect between brands, and stated that the bugs were most likely due to the head unit not reading data transmitted from the 2INpower correctly. The head unit company agreed, and basically said to “Wait a couple of weeks for our next firmware update,” which went on for about 6-weeks, and still didn’t fix the bugs.

Several weeks into the process of trying to sort out the first head unit, Rotor finally mentioned their app, which they said wasn't the most accurate way to access power meter info. It worked better than the first head unit, and really didn't seem to be as bad as Rotor portrayed it to be, though it was still finicky. Ultimately, I ended up borrowing a head unit from one of Rotor's tech guys, that provided noticeably more consistent data, and finally seemed to provide the info I'd hoped for from the beginning - overall average balance output from each ride.

The charging port is hidden behind a rubber plug, although I hardly had to use it.


Performance

Out of the box, 2INpower cranks are calibrated from the factory. although according to Rotor they need to be re-calibrated after installation since the torque applied to bolts during installation impacts the zero-offset. Rotor also recommends recalibrating any time pedals are swapped out due to the torque involved in doing so, and any time the cranks themselves are switched over to a different bike. I recalibrated them once through the Rotor app, or at least I think I did, but I also swapped the cranks through 3 different review bikes, and at least as many pedals. The result? Maybe my exact watts weren’t captured all that accurately. In my case, watts may as well have been nanonewtonkelvins, as I couldn’t really have cared less at the embarrassingly low numbers I was producing - all I wanted to see was how close or far away I was to leg equilibrium. Still, for best results it's important to make sure the cranks have been calibrated properly.

After a few months of intermittent use (I would’ve ridden them exclusively if it weren’t for review-related bike swaps and such), Rotor’s 2INpower cranks definitely helped balance my legs out, but in more of a stern “go sit in the corner and think about what you’ve done” kind of way than actually directly improving my rather extreme lopsidedness. The biggest lesson came after I’d finished a brutal couple of months in rehab with Blood Flow Restriction therapy that helped get my legs to the exact same circumference in several spots. In my mind, equal sized guns meant equal sized bullets, but alas, the little computer display said otherwise. To add to the learning curve, it was amazing to feel just how big of an effort was involved in equalizing a 10% discrepancy while pedaling. It was almost an anaerobic endeavor to get close to 50/50 some days, and if I weren’t looking at the screen, I would’ve bet all the titanium in my leg that about a quarter of the effort above what was otherwise a 45/55 split would’ve been overcompensating. Generally, it seemed like gym work and physical therapy worked best at actually correcting such large discrepancies in power balance, but once I got close the 2INpower was key in staying on track and/or fine tuning smaller wattage variations.

Over the 6+ months I had the 2INpower cranks, I only charged them at the very end, and that was just to see how it worked. So while the charging cord with proprietary magnetic port is ridiculously short(4ft), the good news is you won’t have to lean your bike up at an awkward angle to get to that outlet more than once or twice a year.

As for durability, these cranks were put on a Trek Slash, a Rocky Mountain Altitude, and a titanium hardtail prototype. They took more than a few direct hits to rocks and roots, spent a solid few rides in rainy, slushy Colorado winter conditions, and never hinted any kind of issue from anything I threw at them. The cranks themselves are stiff enough for my 200lbs of torque to not notice any flex, too, though it’s obvious that I’m not producing the usual power someone my size would these days.




Pros

+ Excellent tool for injury recovery
+ Long battery life
+ Durable enough for trail riding


Cons
- Not the most intuitive technology
- Price
- Not the lightest option




Pinkbike's Take

bigquotesRegardless of price, Rotor’s dual sided power meter won’t be for everyone - and we know it’s even more of a stretch for many of you reading about them here. Factor in the price, and the pool of interest ebbs. But, it’s a beneficial tool for cyclists who are looking for any and every way to improve their performance, whether that's from an already high level, or simply trying to recover back to a previous level.

 Does every XC related review on PB have to begin with a near apology? Power meters aren't cool but if you've nearly lost a leg doing something cool--like snowboarding--they're a useful recovery tool (some people wear lyra but I'm not one of them). FYI you do have readers who know how to extract most of the potential out of a modern enduro bike on tech descents who also know their 20m threshold power. The longer you've been at this sport the more well rounded you tend to be.

I'm not picking on Zach. This was a very informative and well written review. I've noticed the "but not lycra" trend with most of your writers. FWIW I wear baggies over my obscenely priced Swiss roadie bibs whether I'm on the enduro rig or the XC/DC bike. Also, XC/DC sounds like AC/DC which is cooler than typing out "downcountry".

 lets be honest XC is definitely closer to the roadie side of things, years ago it used to be core mtb and you were either in the xc, dh or freeride camp. Nowdays mtb is more centered around gravity riding.

 @zyoungson: Your comment is so alien to me, you think XCO WC in lets say Nove Mesto is close to the roadie side of biking? How many roadies do you know that takes the shortcut through a rockgarden like XC riders do? happyride.se/wp-content/uploads/2017/05/Langvad.jpg

In my neck of the woods XC riding is getting closer and closer to trail riding nowadays, nowhere close to roadie riding & i think alot if not most XC riding & riders are riding more and more aggressive XC trails.

I also don't think mtb nowadays are almost gravity centric as you elude to, all bike disciplines are getting more popular every year & alot of riders ride more than just 1 discipline (me myself mostly ride road, xc & trail)

 @JesperA: Ok, the handful of xc riders I have seen recent times (which is very few) have been in lycra, full on carbon everything xc bike, solid seatpost. They tear around the forest like nobodys business when most other people are cruising with their mates, and to be fair they stick out. You have to be pretty dedicated to get around on an xc rig nowdays, im talking 100mm proper xc bike, not downcountry or anything like that, compared to back in the day unless you had a freeride or dh rig, you were basically on an xc bike by default. It is definitely more fringe nowdays, compared to what it used to be.
  • 7 1
 @zyoungson: OK, but what about the countless people just riding relative easy trails in the woods on whatever variety of bike ther"re on, but whose wheels never leave the ground, and are just out there to get into nature and get some exercise?

That's XC - riding cross country, regardless of whether you want to micro-categorize it into "trail" or whatever.

XC and XCO racing is an entirely different animal, and you're right, not too many riders do that, but what most mountain bikers do is ride XC.
  • 13 2
 @hllclmbr: absolutely! XC isn't "cool" so everyone's overbiked so they can claim they ride enduro, when in reality the majority of their rides are on par with a modern XC course. Now, this definitely varies region by region. If you live in the Pacific northwest where Pinkbike is headquartered or any other mountainous region, you may do a larger percentage of gravity riding, but for the average mountain biker it's XC trails.

 @JasonALap: I do a bunch of gravity riding, but I climb thousands of feet first. I still call what i do XC, since all of those 10mm of travel microcategories are silly.

I ride a bike that climbs well, but this being 2020 and all, it descends well too.

 @JasonALap: Yup, especially if your out in the prairies, like I am. Yes, we have a new, up n' coming bike park (Asessippi MB) 30 minutes from where i'm sitting. I'll probably hit it maybe, 3, max 4 times this year. Most of my riding is cross country atv/farm tracks, road ditches, gravel, and practice round the farm. Most of the world of mtbers are in the same boat as me. Either the big trails are too far for practicality, or really expensive to ride, or both. I am on planning to build features round the farm to get some practice in, but my days are so busy with regular life/work, I haven't the slightest clue when i'll get started. We do have some elevation here, good sized hills, so decent trails are possible. It's just the work, to get things into shape that's the killer. So for now, i'm riding not "cool" mtb trails. Big Grin

 @zyoungson: Why do you think they make "Trail" bikes for?... To ride trails...
Isn't that what mtbing is, to go and ride a trail (flat, hilly, technical, gravity, forest track, ect.).
Most of the population doesn't have a gravity park in there back yard, so why do you think companies build/sell so many bikes, other then enduro/dh.
Why do you think Walmart sells more bikes then any other bike business on the whole planet. Most people don't have the money, privilege, or luxury, to afford/bike $10,000 super enduro's, nor do they want to. I'm more then happy to ride my built up, franken ht (100mm airfork, 2.0" tires, 19mm rims, 70.5 degree head angle, fixed seat post, and, dare I say it, lycra Big Grin ). My bike cost under 1,500 dollars so far (Canadian), and i'm having as much fun as you do, on your super duro. Not knocking you at all, i'm happy for you that you're able to have the kind of fun you do, on a bike. But before you knock other riders/types of riding, please check your own privilege, and we'll both be happy/have fun. Now quite talkin, get out and ride yer bike!

 I find it hard every time there is a power-meter review on PB. This one isn't so bad as there is the second story of your injury (hope you're fully on the mend soon, big injuries suck). As somebody who has ridden with power since 2013 I cringe as I read though these every time, the articles rarely actually talk about any of the legitimate technology or advantages of power and always include a "my hilariously low numbers" joke, or "seemed to be accurate or consistent" Well, get a guy who knows power meters to review these very premium products, talk about the downsides, I.E, these specific cranks have the strain gauges in the crank arms themselves, not in the spider between the crank and the chainring, so they can get damaged and are $$$ to replace vs normal arms with a spider PM.

Then skip to the comments which continue to be "OMG, $$$$ for cranks? No thanks!" Yeah, great, but if you knew the benefits and realized this product is unlikely for you, then you'd probably not come in with the most classic PB comment of all time.

PM's are a tricky subject but there you've got a long way to go in producing legitimately helpful reviews of these products.

Otherwise, you crush it PB, don't think I'm a hater.

 Yeah I came to MTB from the road side and I still like staying physically fit and having a power meter is a part of that. On long climbs with technical bits it can help afterwords with pacing too... usually the technical bits require some power thrown at them and I will need to slow myself a bit in other places to not overheat and overwork but each climb is different. Looking at the power file can help.

 I've started training with power (on the turbo) through lockdown and it works so well. I've made massive gains in fitness and power. If power meter cranks were reasonably priced I'd have them in a heartbeat, just so I could match in my outdoor and indoor riding. I can't justify this though - when the difference is around £100 come back and I'll be first in line! Maybe in a couple of years the price will have dropped...
  • 6 0
 Same here, training to power indoors has made my outdoor riding so much better. Even just riding my local hills I've noticed I'm smoother, better paced and less knackered at the top of the last hill on a loop I've been riding for over a decade. Can't wait to see what difference it makes to my riding when we're allowed out to the trail centres and big loops further afield.

If there were power meter cranks available for say a £1-200 increase over a pair of Shimano cranks (so similar ot some boutique models) then I'd be fitting them.

 Your price threshold is wildly unrealistic. Strain-gauge based power tech has been on bikes for over 30yrs. Price has come down from $3000 to as low as $350 for a reliable and accurate MTB power meters (Stages). Companies like 4iiii who have tried to push the price below the $300 mark have earned themselves a terrible rep for reliability. Strain gauges are precision instruments, & you need good engineers to design electronics that provide consistent data capture & wireless connectivity. Over the course of the last decade, we saw the price of reliable, entry-level power tech drop from ~$500 (Powertap Hub) to $350 (Stages XT Crankarm). You can wait another decade and pray that prices hit $200, or you can buy proven tech right now and actually use it while you're still young enough to produce your peak wattage
  • 3 1
 @Veloscente: You're more than likely right, but I don't need absolute accuracy, just consistency. As long as I'm in the ballpark area I can make a judgement (obviously the more accurate the better though!). When there was a PB article on (iirc) $1 chips giving power readings not too long ago, in sure that there is some room to reduce prices for the amateur. There will still be the expensive high end market products available for pros and people who can justify it of course.

 This is the first season I've spent most of my outdoor time on a bike with a power meter, but like you I've used it indoor for the past few years. I can honestly say it's totally elevated my knowledge of my fitness and probably directly contributed to a lot of it. I've increased my ftp by 25% since the start of the season, and it was already pretty okay before this year. Yes they're expensive, but if you put in the effort it can make a hell of a difference. Probably a better upgrade than a lot of things you could get for the money if you're into training.

Also, I just love seeing the numbers. It's super dorky but between the PM and a HRM you get a great idea of how your body is working.

 Training with power is great - but the best way for us average guys to use the data effectively is to invest in an indoor trainer and sign up with trainerroad or zwift. Yes it is pretty dull to train inside, but structured programs produce results - otherwise a power meter on its own only gives you data, and that is pretty useless.

 When I was 22 I ruptured my patellar ligament snowboarding (avulsion fracture of the tibial tuberosity) and did the ACL at the same time. Despite years of physio and weight training, and returning to all the sports I did previously, I was never able to get back to symmetry and over the 2+ decades since, that asymmetry has affected me. It’s a constant battle to try and keep the left leg as strong as the right. This then affected my hips and spine as my pelvis isn’t level.

So I am one of the outliers who sees the value in this. It’s probably too late for me to rise out of middle-aged mediocrity but if this technology was available to me when I was still in my 20’s I think it would be worth every penny to get back symmetry.

In fact people who have had injuries deserve to have this product cheaper since they are far more likely to have had their finances affected.

 Half way decent strain gauges are something like £10 each. Factor in a chip on board conditioning electronics, and Bluetooth, plus cleaning and glueing, if it costs more than £50 in total I'd be shocked. Ok, there are 2 in a pair here, on a nice set of cranks. But $1300 is a bit steep. And rotor have been doing this long enough that development, app, etc have been amortised

 Good job Power2Max can get you a SRAM fit power meter that's more accurate and more durable for $490

 @mountainsofsussex: Sorry, correction, $590 on the MTB side.

Says the guy who installed XX1 Eagle onto a bike that originally cost under $2,000 just today.....

 @mountainsofsussex: strain gauges on their own may be cheap, but what about the engineers? And the hundreds of thousands of hours of testing?

Power meters take a ton of engineering to get right. If you don't see the value in one then don't get one.

 @Azowehn0: to a certain extent, I agree that the hardware is cheap, but development costs may be expensive (especially as I work in development). However, Rotor have been doing power meters since 2012, so realistically it's a commodity product. And their aluminium non power meter cranks are about £200-300.

 @mountainsofsussex: so, they need no new development? No new products? No new features?

Okay.

 There is no justifying £1300 for this product when you can buy a pretty dam decent bike for that money. Doesnt matter how much icing and cherrys you put on it!

 @Matt76: I can buy a pretty damn decent bike for the cost of my rear wheel. So what?

 @Matt76: The perceived “value” of any product is entirely subjective (and so means different things to different people) In addition, value will always be determined by the buyer. This is free market economics, 101.
You and I might not see not see particularly good value in these cranks. We may also not see great value in a $200K Ferrari, a $15K TAG watch or a $2K Michelin restaurant meal. Personally, I don’t. However, that’s irrelevant. Others clearly do perceive a value in such products, hence why they’re brought to market and seem, apparently, to sell.
Horses for courses and all that.

 @Corinthian: Trying to convey your message to people who are invariably driven to a delusional ideal of a panacea of Socialism is senseless.

Just yesterday a woman on a $5000 bike @ a trail near Cactus Jacks was telling us all about how it is unjust that some people can not afford necessities and on and on. So, when I told her to sell her "f**king bike and divide up the proceeds nationally" it kinda got her goat.

For me, I can not at all justify the cost of a Starbucks frappawhateverchino, no issue getting a $400+ cassette body. Power Meters? I have more than one. Over a dozen in the last decade or so.

 @RoadStain: you win the Alex Jones award for biggest stretch to make a thread political.

 @DrPete: Maybe, but, one person deciding the value of an individual item is a political thing. As was said, no one is forced to buy one.

But, for instance, if I were selling EpiPens I would have left the price @ a few thousand $$$ minimum.

 @Matt76: The market will determine if £1300 is “justified.” If they sell them, then I’d say their price is “justified.” If they don’t sell them, then Rotor will either have to revisit their pricing strategy or stop selling them.

My guess that is that since Rotor seems to be in the business of making and selling some very niche product (13 speed, hydraulic drivetrain!!!!) you will continue to see their power meters offered at about this price.

 @Paddock22: Agreed, I have only ever seen the 13 speed on Demo's....I see a ton of guys on bikes, not once an individual owner fo Rotor13...almost as elusive is that reverse fork thing (now bankrupt).

 @Corinthian: Well, if you spend 15k on a Tag watch which has basically got a modified ETA movement you are bonkers. A bit like spending 1300 on a crank that has got run of the mill tech in it!!
  • 2 0
 @Matt76: and people who buy power meters for their bikes feel the same about your opinion of their value. See how that works?
  • 1 1
 @DrPete: Your really are missing the point arent you??!!. The point is i am trying to SAVE people MONEY by calling out this product as a RIP OFF!! And yet you are trying to shoot me down by saying its ok to charge people 1300 for a crank with run of the mill tech in it. Yeah good one!!
  • 3 0
 @Matt76: Well, we certainly see eye to eye with respect to the TAG comment above! However, that doesn’t detract from the point that I (and I notice now others in this thread) are trying to make to you;

Value is subjective. Earlier you said “the fact is this product is ridiculous money...” That’s not a FACT, it’s an opinion. Yours. And it’s doubtless an opinion shared by many reading this (me included as it happens!) but what it absolutely is not, is a FACT. Facts are known and provable truths. Gravity exists, that is a fact. Night follows day, that’s a fact. What we’re discussing here are opinions and what’s emerging from our discussions here proves the point: notice how several contributors here have different OPINIONS about the perceived value of these cranks..?

You mentioned it infuriates you when you complain about a product’s price and get shot down for it. It infuriates me when I see comments conflating price vs value. The former is a fact (the price) and the latter is an opinion (the value).

Somewhat weirdly, I don’t think our views actually differ much with respect to these Rotor offerings (as I said, they’re certainly not for me!)
But others will of course have a different opinion...

 @gatokl: the meter shows 110 watts. I would say an average fit rider would do twice as much. As average.

 @RedRedRe: most riders can't average 220 watts lol

 @clink83: I am referring to "fit" riders. Then power does not mean anything without rider weight.
