PRESS RELEASE: Sector Wheels

Introducing the 9i Wheelset:

29er Carbon Wheelset | Innegra Armoured Rims | 1690g | 29mm Internal | Boost |Trail & Enduro | Lifetime Warranty| SRP £1100 | Shipping Worldwide (Free to UK and Europe)


First, a little about us...

Sector Wheels is brought to you by the award-winning teams behind DMR and Kinesis UK. We’ve got a track record of creating industry leading products that win group tests and ignite the passion of riders all over the world. Our goal is to deliver innovative high-performance products that are value for money, and ready to stand the test of time. We may be relatively new as a wheel brand, but if you are familiar with our other products you'll know that we build things to last...


Enough about that. What are these wheels?

We were looking at enhancing the structural properties of unidirectional carbon in the application of an MTB rim, with strength and impact resistance being primary considerations. Working closely with Paul Lew (composites and aerodynamics expert) we established that the introduction of Innegra fibres had the potential to significantly improve the properties of an MTB rim. After a period of research and development, we are now ready to present to you, the 9i wheelset.

The 9i rim not only has the lightness and toughness we were looking for, but has the additional benefit of significantly more compliance over standard carbon rims. The 9i wheelset has the lightness associated with a carbon wheelset, but with the ride quality of a premium alloy wheelset!

TeXtreme® Spread Tow Innegra fabrics give the unique appearance of the rim


So what is Innegra?

Innegra is a fibre derived from polypropylene that exhibits some highly beneficial properties, including high strength-to-weight ratio, resistance to damage, vibration damping and energy dissipation. Because of these properties, Innegra is already used in numerous other applications - including boat hulls, kayak paddles, F1 fuel tanks and body armour.

The TexTreme fabric used in the layup of our 9i rim is a Spread Tow fabric built from a hybrid of Innegra and standard carbon fibres. The Spread Tow layout is significant because it also contributes some positive attributes – the fibres are straighter (reduced crimp therefore higher strength) and it facilitates the use of less resin (lower weight). In the 9i rim the Spread Tow fabric is used on the outer layer of the rim, giving it the unique checkerboard pattern.


Spread tow fabrics are mechanically better than standard carbon fabrics for rim application


Sounds good, but what does that mean for a rim?


• Significantly more compliance...

Under a lab test the 9i rim was 50% more vertically compliant than a unidirectional T700 carbon rim of the same profile. This test involves loading the bare rim with a 100kg weight, in which the 9i rim exhibited a deflection of 15.74mm compared to 10.55mm on the standard T700 rim.

It is widely acknowledged that vertical compliance is important for damage reduction (less prone to catastrophic failure), a reduction in fatigue and improvement to traction. But additionally, such an increase in compliance also brings a radically improved ride quality to the 9i wheelset. The Innegra wheelset has none of the harsh stiffness of regular carbon wheels.


Lovely riding wheels!


• Significantly more impact resistance...

In the lab, the 9i wheelset withstood a massive impact of 140 Joules compared the UCI stipulated requirement of an 80J impact, and was also 75% stronger than the standard carbon equivalent! In real world terms, the 9i rim can handle the equivalent of dropping a 15kg weight from a height of up to 1.08 metres onto the bare rim, thus making it 18% stronger than a recognized leading competitor who has published their data.

Rock gardens? No problem


• Much less weight...

Despite offering strength and compliance advantages, the use of Innegra also allows the construction of an extremely lightweight rim. The Innegra equipped 9i rim weights just 428g (29”), and our complete wheelset comes in at just 1690g.

A wheelset for climbers to love


What about the rest of the wheel?

Every detail of our wheel builds is carefully considered, from the super smooth Revo Cream bearings (in standard bearing sizes) to the straight pull triple butted Pillar spokes. This wheelset is designed to last, and be easy to maintain. And we back it all up with a lifetime manufacturing defect warranty.

I don't ride 29"/Boost, What about me?

We offer the 9i as rim only in 32 hole and 28 hole, and there is also a 27.5" 7i rim in 32 hole for those that want to build in a different configuration. The eagle eyed will notice that the bike in the photos is a Pivot Trail 429 which has a Superboost rear end. Needless to say, we can build Superboost spacing wheelsets on demand!

In all seriousness, it’s not easy to launch a product that ticks boxes for quality, durability/warranty backing and nailing a good price point. Rather than complain the name is to similar To i9 you should make your own stuff If it’s so straight forward or give these guys a pat on the back for throwing their hat in the ring with what looks like a great product. Let’s build each other up, not tear each other down. Nice work @sectorwheels!

 @howie286 you work at sector?

Have you tested it? You already claimed that they have all the promising benefits and features...
9i, maybe a marketing, maybe it's intended to ride on I9's popularity, or maybe not.
But if you want to stand out and differentiate yourself from the rest, thinking of another name than 9i would be a good start...
  • 8 4
 I agree with you here, they published all the impact testing data behind their rims and are offering a competitive product at a good price. We should hold this up as an example of the right way to launch modern MTB product. I, for one, really enjoy when a company publishes technical data about their product, be it how many joules it takes to break a rim or a suspension leverage curve. It helps inform my decisions on what to spend my cash. Look forward to a review for these wheels!

 Thanks guys. We want to lead a change in the industry and be very open with our impact and compliance data. If other manufacturers did this you would understand why so many crack! We know this product is awesome, we wouldn't bother if it wasn't, as frankly the world doesn't need another 'me too' carbon wheel brand. If the worst thing people can say about us is the name then we are happy with that!

 "straight pull triple butted Pillar spokes" and "easy to maintain" is an interesting choice of words

 @crazy-canuck: Never had a problem with Pillar spokes. I've built with DT, Sapim, CN, and Pillar. I can't tell a lick of difference between them except price.
  • 1 1
 @JohanG: Fair enough. My experience using Pillar spokes and nipples has primarily been failure of the nipples, however I have seen a small number of the spokes snap at the end of the threads. (All were aluminum nipples, stainless J-Bend spokes on open-mold carbon road rims at a shop I was at for a couple summers). When we switched over to Sapim spokes and nipples the problems went away.

 my issue is local shops often don't stock them, so "easy to maintain" is questionable.

 you know you will never feel "vertical compliance" in a wheel on a trail. Deflection between wheels will be less than a mm. Great marketing piece.
  • 13 2
 Yep. You'll get more vertical compliance by reducing tire pressure 1 psi.
  • 3 1
 But you do!!
  • 4 0
 A riders perceptions are tricky. You may never feel that your current wheelset isn’t compliant enough, but you could slap these on and realize that you’re corner faster and and feeling more comfortable in general. Most riders will probably never “feel” that a Fox 36 is too flesh, but swap it out with a 40 and they’ll notice right away how much better their bike handles in all situations
  • 4 0
 You do actually. A rim will 'give' or deform quite a bit under load. Its surprising how much a carbon rim will flex radially and spring back to its original shape.

 @jaydawg69 I "tested" this with an extra carbon hoop I have in my basement that isn't laced up to anything yet. I put it on my tile over concrete floor, so I know thats not where flex is coming from, and then I compressed it with my body weight (around 95kg). It flexes at least a few mm. Anyways, its not just about taking the edges off big hits, its about vibration reduction. When you hit a curb at speed, the tire bottoms and hits the rim before the suspension moves a single mm. When you hit stuff thats not big enough to get your suspension moving, the vibrations travel up the wheel, fork, frame, and into your handlebars and hands. If less is transmitted from your rim into your fork, then less hand fatigue and less "harshness".

Also, as said before, if there is some lateral and torsional compliance in the rim, then the tire will conform to the ground a little bit better, giving you a little more grip.
  • 2 0
 @hamncheez: like an alloy rim?
  • 2 0
 @jaydawg69: Yes, but without the constant need to be trued every week, getting dinged on even medium sized hits, flexing too much when pushed in hard corners, weighing more, and having terrible resale value.

And before you respond with "World champs was just won on alloy rims" these DH bikes are now mostly mullets, so the rear isn't a 29er, they rebuild/replace them nearly every race, and they have uber professional mechanics keeping them true, where I just have my fat bear paws to try and true rims with.
  • 1 1
 @hamncheez: I'm seen and had numerous carbon rims fail. I'm really not sure there is a ROI with carbon wheels. I just put on a new Flow EX3 with a RimpactMTB insert and we will see how that works out. Carbon rims and sharp impacts don't go well together... think of an axe and a tree.
  • 2 0
 @jaydawg69: I've been riding carbon rims exclusively since 2014, when I also exclusively switched from 26" to 29". I've cracked a few carbon rims, but I was destroying aluminum rims at a much higher rate before. Not the best direct comparison, as I hope my riding has gotten smoother, but still I much prefer carbon rims, and thats with cheap chinesium carbon! Higher end stuff must be even better.

 We put our hands up here, totally should have checked the redirect from the blog! As we mentioned, we are a new product from the same people as kinesis uk and dmr. So the website lives there for the time being. This doesn't affect the quality of the product though!

 How does this work PinkBike? Is a product announcement written by the product company paid advertising, free advertising, or "journalism"?

I'm reading a lot of unsubstantiated claims in this article. eg "75% stronger than a standard carbon rim" happens to be the UCI stipulated 80J. Incredible.

so many questions...
  • 3 1
 Not an article. It's a press release.
  • 6 0
 Thanks for the comment. We like to provide data rather than pure marketing superlative. What would you consider substantiation of these claims? A graph? A photo from the factory? Video of Danny mac riding down the stairs? We can provide those (maybe not Danny mac) but really the problem is a lack of trust because companies don't usually give you any data.

In truth, all mtb rims must meet an impact test measured in Joules (set by ISO) to be sold. The UCI standard of 80J is required by the UCI for products racing in UCI events and is much higher than the ISO. But other than meeting the ISO standard, who knows how strong most carbon rims are. We have provided some data to demonstrate we meet and exceed the recommended UCI impact resistance, by a long way. If other manufacturers provided this data too you would see just how well we stack up. For some comparison we also made the rim in standard T700 carbon fibre to demonstrated just how much difference Innegra makes.

Hope that helps!

 Engineers are often terrible at many non-engineering things. Perhaps this is an excellent engineered product that's happy to stand up to testing...along with a zero budget marketing job done by someone already burning the mid-night oil. I could care less as long as the product is legit and the price is nice.

 Some of the descriptions of the fiber in this article sound like they were written by the Christmas Vacation crew.....

 Thanks for the input! We tried to put the advantages of a.) The Innegra fibre and b.) The spread tow orientation of those fibres into easy to read terms, and hopefully avoid making unjustified marketing claims. We didn't invent Innegra, and a quick bit of research should back up the claims!

 "The 9i wheelset has the lightness associated with a carbon wheelset, but with the ride quality of a premium alloy wheelset!"

But weren't carbon rims supposed to offer superior compliance and rigidity at the same time!? Good thing I went with old tech alloy rims!
  • 4 0
 Other manufacturers might claim that, but in reality lots of carbon wheels are horribly stiff. With these wheels you can get the weight saving of carbon wheels, with a much greater impact resistance, and more compliance. And we back up these claims with testing and data! You pay for these qualities, but we like to think the price is justified and we place value high on our priorities!

 The naming sounds familiar: "See, they're McDonald's... I'm McDowell's. They got the Golden Arches, mine is the Golden Arcs. They got the Big Mac, I got the Big Mick. We both got two all-beef patties, special sauce, lettuce, cheese, pickles and onions, but their buns have sesame seeds. My buns have no seeds."

 Compliance may well add strength to the rim but it adds more stress to the spokes...which will eventually fail spectacularly and thus create more stress to the rim which will finally break too. Or you'll have to true the wheel every other ride. Not fun. In other words, I don't think adding compliance to a rim is a good thing for a wheel.

If we're not going to bother with a hub and spokes, perhaps we should test it as a hula-hoop.
  • 4 1
 The hub and spokes are important, and we have carefully selected these. But for the purpose of a press release and the technology we are focussing on, it's all about the Innegra equipped rim. Smile
  • 4 1
 man! that's the way rims are being tested. You have to isolate the component in order to compare direct values for stiffness and strength if not it has no sense. Otherwise with spokes preloaded and the hub you have more variables that affect your structure.
  • 1 1
 @avg: ... if not it has no sense

It has no sense. The product is a *wheel*, not a rim. To the extent rims flex at all on the vertical, they're severely constrained by spokes. I'd sooner fondle a connecting rod to evaluate an engine.
