Found: Energy Labs Unique, Affordable Carbon Clincher Aero Road Bike Wheels

Energy Labs affordable carbon clincher aero road bike wheels

Developed and built in Calgary, Alberta (Canada), Energy Labs aero road bike wheels use a few interesting and unique designs and build techniques to bring things in at an affordable price.

Energy Labs is a relatively new company, having started and developed and tested the wheels over the past 12 months. Using feedback from pro triathlete Simon Whitfield and drawing on the area’s wealth of engineers, they’ve just launched 60mm and 90mm deep wheels, and 40mm options are coming soon. The full carbon rims are their own design. The hubs are their own, too. Both were developed with durability and price in mind by making shop mechanics and warranty managers their first source of research. By learning what was failing on other brands, they could reverse engineer solutions to overcome braking heat failures, hub failures and other common complaints.

The result? Full carbon rims with unique brake track placement and internal heat disbursement chamber, all covered by a three year warranty. Roll down to see how it all comes together…

The rims use a symmetrical toroidal shape, a common aero shape that they say provides good aerodynamics and stability in crosswinds. The layup is four layers deep, each at 40º to each other to improve strength in all directions. What separates it from others are three main things: A taller braking surface area, the internal “Heat Disbursement Chamber” and inverted spoke nipples.

The brake track is a very tall 15.5mm and it’s beefed up with a bit of additional material so there’s more “stuff” to absorb then diffuse heat build up. It’s also machined during finishing to remove any residue from the molding process that could reduce brake pad bite.

The large open space inside the rim is their Heat Disbursement Chamber. Basically a large open space that gives excess heat one more place to go, not unlike most other rims. During construction, the carbon is laid up over a solid surface, with the bladders underneath. This provides a smoother, more uniform internal finish with no concern that parts of the bladder will be leftover in the carbon. All of that material is removed after curing, so there’s nothing extra left to add weight (which could unbalance the wheel) or affect heat build up/diffusion.

The rim bed is dropped lower than normal to reinforce the sidewall where the brakes clamp down. These pictures show how deep it gets, which also means higher air volume. That, plus the rim’s wide 25mm external stance at the top, should make for a pretty comfortable ride. They’re designed around 23c to 25c tires.

The other unique design trait is something you’ll hopefully never see. Inside the rims, the spoke nipples are inverted. The internal shape is designed to cradle the larger “mushroom” top shape of a spoke nipple, which they say improves the carbon-to-spoke surface strength by 152%. In other words, there’s more contact area between nipple and rim to better distribute the forces and help things last longer.

Kelly Zwarych, who works with Energy Labs parent company and Canadian distributor Kazak Group, says the idea behind all of this was to “build savvy and bullet proof products at an affordable price. Early on we mandated that EnergyLab build their rims to target the person who is becoming more passionate about cycling and triathlon but has to work within a budget, but doesn’t have to sacrifice any thing in quality of product.

“Simple ideas like flipping the nipple saved dollars over a unique property nipple by keeping costs down, increased the spoke strength to carbon relationship and made the shops happy because they could easily service the wheels. No special tools needed. It’s working so well, we’re even testing these wheels for cyclocross.”

Along those lines, they also include extra spokes with the wheels. Zwarych explains:

“Another great idea that came from the warranty managers was include a spare spoke for each length in the wheel set. This was driven by economics as most shops have to buy a box of spokes and often end up charging the customer a small fortune or basically write off the other 49 spokes in the box of 50. Rider enjoyment was also important with short riding season in some areas the idea of a rider being back on the road in a couple days compared to weeks was powerful. Not all shops stock all the length and need to order which often takes a couple weeks.

“This idea of the extra spokes really hit home when I went to race in Cozumel. It’s a great time but I didn’t realize the local scuba shop is also the bike mechanic shop and tequila bar. Limited…. I mean limited parts, spokes good luck. If you popped a spoke training the course you’re not doing the race. Its easy to stick the spares in your luggage with the sun screen and enjoy your racing vacation.”

The wheels all use bladed straight pull spokes with easy, drop in installation at the hubs. The rear hub uses six pawls with 12 points of engagement. They’re compatible with current 11-speed drivetrains, including Campagnolo freehub options.

The 60/90 wheelsets should ship at the end of July 2013 and are sold direct via their website while they set up bike shop accounts. The 40′s should be out by mid-September. They’ll have both Canadian and US distribution centers. Expected MSRP and claimed weights:

  • VC40 – $1,299 – TBD
  • VC60 – $1,399 – 1757g
  • VC60 front / VC90 rear – $1,499 – 1807g
  • VC90 – $1,599 – 1857g

Zwarych says they’ve booked time at the University of Calgary wind tunnel. He says initial testing shows they’re competitive, but the upcoming tests in Calgary will allow them to test at various humidity levels, which should provide some interesting data all on its own.

It really bugs me when companies lie about producing their own products, especially when it’s so easily found in forums. These are the new wider Hongfu rims (they even have the same rim profile images as from the Hongfu site), there is nothing designed or engineered in Canada about these wheels.

The only thing engineered in Canada is likely the decals.

Cat se7en - 07/13/13 - 1:53pm

Here’s the same rim profiles in tubular and clincher from Dengfu, a Chinese reseller for Hongfu.
http://dengfubikes.com/images/HeadAdvertising/wheelset.gif

Thomas - 07/13/13 - 4:05pm

Hmm

a week ago I ordered a wheelset from dengfubikes.com. The dimensions of the rims they sell are EXACTLY the same as these! The Price however is quite different!

Is it the same rims, openmold, or just coincidence?

Aaron - 07/13/13 - 4:34pm

Compelling wheels but… They spoke with shop mechanics and warranty guys and they STILL went with internal nipples? I just can’t fathom that there are any advantages to such a design, except slightly enter aerodynamics and aesthetics… Otherwise they’re a pain in the butt.

EnergyLab - 07/13/13 - 6:58pm

The reason for the internal nipple was strength keeping in mind simplicity.

couple measurements:
spoke is 2mm
Nipple at the wrench point 4mm
Nipple at the head point 6mm

With an external nipple on a carbon wheel that is only 2mm or 1mm circumference for a spoke hold to the rim. With the internal nipple you have 4mm of nipple to carbon relationship which was substantially stronger.

When doing this we simply reversed the standard nipple and that was the difference for the shop mechanics because its a common tool and the home mechanic can pick the wrench up for $15 to $20. By doing this we also did not have to re-engineer or us a proprietary nipple that would drive up the consumer cost.

Your right if it was a priority nipple when we have seen in the past shops having to buy a little wrench for $100+ which is not the case here.

EnergyLab - 07/13/13 - 7:21pm

Internal Pawl on Rear Hub – It’s interesting that our internal pawl system is something Easton is moving towards. Easton has been plagued with hub problems and their solution is an internal Pawl system which I put as a testament to our design team.

Andrew - 07/13/13 - 7:31pm

Not really a pain on a clincher. The aero advantage is probably worth putting them inside (never on a tubular though). I really like how 3T does it though, you true the wheel at the hub.

greg - 07/13/13 - 8:48pm

most studies have shown that putting the nipple inside is NOT worth it.
inverting the nipple isnt new. been done on lots of carbon wheels before. some FSA/vision more recently. internal hex nipples are far from proprietary these days. are you dragging the nipple’s screwdriver flat right on the spoke bed? or is it smooth there, and therefore NOT an off-the-shelf item?
misleading-that their wheels are built in Canada. i’m gonna assume the wheels are assembled there. and when they state that the hubs are their own, it means it has a particular set of dimensions and options that their hub vendor does not supply to anyone else yet.
so they chose a symmetric toroidal shape. great. did they model it with CFD in 3d in a rim shape? did they tweak the shape to best suit the intended purpose? why did they choose this shape in particular?
…and these are final products, yet to see a wind tunnel. it’s a bit too late for validation.

Greg @ dsw - 07/13/13 - 9:23pm

There is a sentence the *rims* themselves are handbuilt in Canada. But is this truly correct, or not?

mikew - 07/13/13 - 10:13pm

Yeah, these are Chinese rims. Actually Deng-fu makes these new wide rims. They are not Canadian made. In fact, they even ripped off the rim profile graphic from the Deng-fu website. Not really smart of them if they are lying about the rims being made in Canada.
http://dengfubikes.com/images/HeadAdvertising/wheelset.gif

Tim C. w/ Energy Lab - 07/13/13 - 10:53pm

Greg is right There is an editor error as these are not made in Canada. They are designed and engineering in Canada. The inverted nipple isn’t new but definitely smart. We have seen several complained do patents and re-engineer nipples causing problems for the bike shops to do repairs quickly.

Regarding the hubs you will see that we do an internal pawl system. Until recently we look to be the only designer of this but I understand that Easton has dome this to fix hub design problems. Interesting that we went down this road early on. We also went to a 6 pawl over a 3 pawl. Both of these options made the power quick responding and reliable.

Regarding the Hubs we designed them again from problems see in other hubs. We wanted to prevent side bearing pressure that has plagued some other wheels. One thing that really was driven home was spoke replacement. Did you know that spokes often need to be bent to feed into straight pull hubs with a small hole! Think about that… You have to bend a 2mm spoke to feed it into the hub potentially weakening its metal? Smart, I think not.

The intended purpose was to make a solid and reliable rim that was effective. This is why we did the 4 layers of UD. Early on we did some tests with 3K but didn’t like the test result. They looked good but failed. Check out the tolerance tests on the web site http://www.EnergyLab-Sports.com

CFD is cost effective and done at the UofC. The reason we are doing testing in Canada is the low spped wind tunnel has the capability of bringing into the equation humidity. Molecular flow is going to potentially have different attributes in higher humidity then lower humidity. So air flow in Arizona is potentially going to be different then in Hawaii…. Will it be substantial? We will have to wait and see but it will be a first.

The shape was chooser for several reason, ride comfort, rolling resistance, easy of tire changing, better side wind (yaw) performance which lead to a winner for overall performance.

If you are looking for a really snappy and precise ride this might not be your choice. I would recommend a tubular with a 18 or 19mm tire. But, you feel every rock and crack and its a great choice for the fondo or ironman rider.

Anonymous - 07/14/13 - 12:10am

…So basically their magical Heat Disbursement Chamber is just the open space inside the rim that you can find on any other carbon rim as well? That’s clever. I’m going to start selling tires with a Advanced Damping Chamber in them that you have to fill with an inner tube and then pump up with air. Totally groundbreaking technology that is..

Tim C. - 07/14/13 - 12:17am

Rims with latex bladders that are mot removed have problems in this area as well as imbalances int he wheel rotation at high speeds.

Hoppy - 07/14/13 - 12:22am

Internal nipples are in compression not tension. This means a lighter smaller nipple is required. Smaller holes are required in the rim and you shouldn’t lose tension on the spokes as fast. Unless you’re running tubeless it doesn’t take long to remove your tyre and tube. That’s the advantages to such a design. Just for your info Aaron.

RoDe - 07/14/13 - 6:33am

They aren’t lying about building the wheels in Canada. They never said anything about manufacturing. Building a wheel to me means building a wheel out of components needed to built a wheel. Manufacturing is a whole different animal. Now if they had said we manufacture our won wheel they would have been lying.
But I get what some of you are saying. I personally hate it when Bikerumors or other webpages post an article that says: A visit to the Rocky Mountain factory or something of that kind. What you mean factory they don’t make anything!? Assembly line maybe but factory no. You want to see the factory you need to go to asia.

EM2 - 07/14/13 - 7:29am

humidity and Molecular flow seriously ?
tell me more so i can LMAO 2.8% more than with the “Heat Disbursement Chamber”

quickgeezer - 07/14/13 - 8:04am

They look nice; shouldn’t be a surprise, at this price, if the rims are made in China.

But, holy crap, could y’all look up the words “disburse” and “disperse”?

1Pro - 07/14/13 - 8:46am

you can “design and engineer” in canada all you want but until your volume in china can afford a man on the ground full time, you are getting whatever they want to give you. thats just the law of economics in this ever expanding world of marketing companies that outsource and lie about it.

Tim C. w/ Energy Lab - 07/14/13 - 8:56am

Technology comes from the USA and CDN but some of the parts are made in China. Guess that’s why we don’t see Chinese cars. Parts are defiantly made there for the cars.

What cycling company doesn’t have parts or assemble done outside of North America.

Max - 07/14/13 - 9:32am

Thanks bikerumor, lovely joke! I laughed hard!

HD Chamber :D, wind tunnel testing with different humility :D, 40° Layup* :D

*4x 40° = 160°, so you are miss a 20° angle in which direction no carbon fiber can handle any load with full strength. Wired :)

Tyler Benedict - 07/14/13 - 9:54am

All – updated the article to better clarify that the wheels are built in Canada, not the rims themselves.

Max - 07/14/13 - 10:00am

Hey Tylor, there is more to update ;)

“The full carbon rims are their own design”
to
“The full Carbon rims are bought from dengfubikes.com”

T - 07/14/13 - 10:12am

I just designed a set of these last week. I call the air chamber the Large Induction Element System.

EnergyLab - 07/14/13 - 12:04pm

EnergyLab has contracted staff in China with the lead living between China and Calgary. This is the only way to control manufacturing. Check out the spec controls at http://www.EnergyLab-Sports.com

Regarding the rim profile you will find that the majority of China website are brokers and not factories. This is why you will find brokers dumping no name rims on eBay in the USAWe are checking into this Defung Bikes but I can assure you they are not from this eBay broker.

If Defung is a reputable rim maker who else do they do rims for?

GearHead - 07/14/13 - 12:24pm

This Defung company looks to an eBay broker doing knockoffs? Anyone know if they build rims for someone else. I see someone commented they purchased off eBay. Could Defung Hong Kong company be copying these guys? Defung site also has Cervelo frames?

I know I can also buy Zipp knock offs on eBay? Are they from this Defung company on eBay?

Tim C. w/ Energy Lab - 07/14/13 - 2:43pm

Looks like Dengfubikes.com is a knock off good designs. Some really interesting designs especially on the frames and wheels.

Is Ness a knock off company in the California as I do see their name on the Dengfu site?

Max - 07/14/13 - 3:10pm

Oh guys,

go to an exhibition and you will see a lot of asian companies with differnt nice products. Visit the same exhibition in the following year. You will see a lot of European, American (and now Canadian) companies, which printed their label on this items. Then they add some marketing buzzword stuff while they are ignoring physics and claim all is their design.

Max - 07/14/13 - 3:33pm

Bending Spokes won’t harm them unless you lag of any fine motor skills. Most Hubs only need a slight bending of the spokes, which is reversible and so the material is not harmed at all.

Cat se7en - 07/14/13 - 4:08pm

I would believe more that a start up company found these rims, didn’t think that anybody else would recognize them, and claimed they designed them. Engineering carbon layup schedules, resins, moulds and such in house costs tens of thousands of dollars. Buying rims off of Alibaba costs a few hundred bucks for a set.
It’s not the first time a company has lied about using open mould rims and claiming they designed them. The only thing engineered in Canada is the decals.

EnergyLab - 07/14/13 - 4:28pm

Spoke Bending, on some hubs can be substantial and why put the spoke at added bending if its not needed. It also allowed for different bladed spoke options without being limited.

I have a feeling you are going to see more of this design and the internal pawl drive system that Easton and EnergyLab has adopted.

Gravity - 07/14/13 - 4:30pm

GearHead – Many hubs use or have used this design, including (just what I can remember) Rolf/Bontrager, Reynolds, Mavic and Easton. Probably dozens more, as well. Anyway, as Max said, bending a spoke, especially a steel one, is absolutely not a problem. As a mechanic, I can count on one hand the number of times I’ve seen a spoke break at the head, and I’d wager that every one of those broke for a reason other than the initial bending of the spoke.

Gravity - 07/14/13 - 4:38pm

One of two scenarios is likely with the rims – Either they are mass-produced by Dengfu company and these Canucks stole the imagery, or they are mass produced by another Asian manufacturer, and both Dengfu and Energy use the same imagery and graphics when they retail them. Either way, Energy is lying about their rims origins.

tricycle - 07/14/13 - 5:39pm

this is just like that broken bones company that BikeRumor did a story on last year. Do a search for them on here and you’ll see the same thing. Buy from a Chinese company and claim you did the design.

Does anybody else get the feeling that Jill and Gearhead work for Energy Lab?

Bart - 07/14/13 - 5:46pm

I have looked at these wheels personally and they surprising. Hub design is logical and easy to pull apart and bearings are well seated and supported. Freehub is very similar to Easton’s new design and should do quite well. What makes me laugh is everyone talking about Dengfu and whether Dengfu is the manufacturer or not. Who cares? most bikes are made by 3rd party and we never have issue with that. What are you going to do with your Dengfu rim if it has a warranty issue? send it back? Wait who knows how long for a replacement? What you have here is a company willing to put their name on some decent stuff that they have helped design and develop with a 3rd party(more than likely) and take a bunch of risk for the consumer to have an inexpensive performance wheel set with good support. Sounds like a good idea from a consumer standpoint and a shop standpoint cause I sure don’t want to deal with a company overseas! And to pay for an exclusive rim was probably not in the budget… so whoever the 3rd party may be I am sure they are going to try and take advantage of the design and sell some rims(probably all the seconds), Dengfu or not.

GearHead - 07/14/13 - 6:09pm

tricycle – Gearhead doesnt work with Energylab yet, but we are going to carry the product in our shop. I think Bart summed it up perfectly.

The wheels fit a consumer market that we as a store havent been able to provide to our customer.

I'm on a boat - 07/14/13 - 6:52pm

Gang,
you don’t like said product on BR, then keep your fingers to yourself and move on.
You want to buy products w/o warranties, then have at it, see you in the hospital.

I like the wheels/hubs and designs. Nice work Energy Labs.

Chris - 07/14/13 - 7:05pm

Why ‘design’ and produce the wheel then wind tunnel test it? Seems to be the wrong order….

greg - 07/14/13 - 7:36pm

@Chris,
i asked this earlier as well. i guess it’s to see that, although the actual numbers may vary due to humidity, drag versus other wheels/shapes is proportionally the same. sounds like a high school science fair project to me.

Tim C. - 07/14/13 - 10:47pm

Wheel aerodynamics or any aerodynamic design could not have progressed without CFD. Its not 100% accurate science but is more effective on several levels. You can read time after time CFD being validated in the LSWT.

During the design stage we created two models prior to the 3rd and final model. The previous models failed for one reason or another. One of the models was exceptionally fast but unstable at a specific speed and yaw. It was dangerous when these two conditions were present in a ride.

The final model was using available data with a few adjustments to allow for better control overall and at high speeds, which is when most problems will magnify themselves.

Net result is something that was real world tested and an amazingly versatile ride. This rim might not be for the rider who needs the extra 2 min over 180kms ride for the prize money. But, I can guarantee that the age group rider who wants performance, versatility, comfort and a few dollars in their pocket has found the right wheels.

We look forward to post our lab results when completed, as the idea for humidity is interesting and yes nerdy. Any techno-winnie (yes some of the staff fit in this category) will be interested in the results simply because its makes any open-minded designer or engineer interested.

Comments are opinions, the tests are results and I have a feeling several people will be quietly interested in the end results.

Thank you to the supporters….Eh!

Bog - 07/15/13 - 1:18am

Internal nipples are not cool on anything but race wheels. On several occasions I’ve seen friends have a spoke break which has meant that the wheel goes out of true and rubs on the chainstays. Since the nipples are internal there is no way to true the wheel on the road to get going again. This has become more prevalent with wider rims and wider tires because chainstays haven’t gotten much wider. Bad, impractical idea.

tricycle - 07/15/13 - 9:29am

@Bart It’s not a question of if Energy Lab is using Dengfu rims or not. There are lots of wheel companies that are using open mould rims. They probably are decent rims and the fact that there’s a warranty and local service is a big plus over ordering the rims direct from China.

But the fact that Energy Lab is LYING to all of us about engineering the rims does not instill trust from me. If they are lying about engineering the rims, what will happen when there is a warranty issue? If they were upfront about the fact that they saw these rims and knew they could build decent wheels with them I would be interested in this company. People are going on forums a lot more and there is no way they are going to get away with claiming these are their own rims. . .we’re smarter than that. And shame on you Energy Labs for thinking we’re not!

Tim C. - 07/15/13 - 12:26pm

Please read through the posting stream as you will see a couple key points related to your claim:
- Dengfu looks to be a China knock off company that sells on eBay: you can also purchase:

2013 EnergyLab VC60: Looking at the banner attachment in a early posting we can not find design layouts on their web page but only on the banner. This make these rims look to be in the process of being knocking off like the products listed above. The word “Fiber” and the banner doesnt link making it look as if Dengfu is a broker and not a factory.

During our factory search we have gone trough a lot of brokers and factories that could achieve what we needed in 2012.

EnergyLab has designed and engineered their wheels in Canada and are manufactured in Taiwan and China at our inspector approved factories. *The editor has noted they made an error in the article posting as we are not able to proof prior.

EnergyLab have gone through 3 molds with the final version aggressively field tested.
*EnergyLab has high quality standards noted on our web page under “Lab” with tolerances of .03 to .05mm.

EnergyLab in no way is manufacturing, purchasing or doing any production with Dengfu. If in the future EnergyLab looked at manufacturing at Dengfu factory assuming they have one, they would be required to meet the listed quality standards set forth in our factory approval process and be subject to factory inspection.

erikv - 07/15/13 - 5:02pm

You lost me at bending spokes is bad.

You have to slightly bend a spoke to stress relieve it. Or is that not done anymore?

Max - 07/15/13 - 5:35pm

@Tim: The Time Trail frame von Dengfu differs in some points from Scott. Its the same with the “pinarello knock off”

But your rim profile is the same within 1/10 mm and dengfu offers this rims some time longer than you do. Plus your marketing texts are lagging substance. HD Chamber and such claims which are lagging substance wont support your standpoint.

Article in VELO NEWS on limitation of Wind Tunnel. New Technology Meter captures air temperature, pressure, and HUMIDITY.

Companies embarrassing the new technology include BMC, Giro and Zipp (they might know something about air flow dynamics from their high school projects).

Technology is at Los Angeles / Home Depot Velodrome…. these Canucks again? Please dont hate Canadians its just not neighborly.

Not a good experience with this wheels, first cracked on the rear wheel just by pump air before my first ride. They replaced no questions asked.

Then, had couple rides and when to my fondo ride, after the fondo 2 lose spokes. I am 237lb rider and initially they had a weight limit on their website of 245lb and recently they lower that to 225lb.

That tells me they didn’t test it properly.

Now, to be fair, without the issues, I loved the wheels, they were fast, responsive and very comfortable ride. I guess they are just not for me yet…
