Aussehen tun die ja schon mal sehr nett, aber wollen wir mal hoffen, dass die Speichen nicht durchgängig so gemacht sind, wie die Deckschichten. Hinten anders als vorne, hinten ganz unsinnig, vorne mit 50% unnützen Fasern...

Die Speichen sind ja sowas von schlecht gemacht. Überhaupt nicht materialgerecht. Massig per Kleber gefügte Verbindungen. Speichen nicht aerodynachmisch geformt und dazu noch sehr breit. Bei Seitenwind bremsen die mehr, als das sie einen Vorteil bringen.
Die Naben schauen auch nicht besonders toll aus.
Die Optik...naja...billig.

Hier deren offizielle Pressemitteilung (nee, ich hab nix mit denen zu tun...) Da sollte man alle Angaben entnehmen können:

For immediate release
May 16, 2010
Mad Fiber™ introduces road wheelset.
Carbon optimized design sets new standards in performance.
About Mad Fiber™ Road Wheels:
Aerodynamics, light weight, durability...

There was a time when riders would be faced with choosing between these attributes when selecting wheels. But that time is gone.

With 60mm (front) and 66mm (rear) deep rims, 12front/18rear bladed spokes and narrow flange spacing, Mad Fiber Road Wheels have been validated in the San Diego low speed wind tunnel as being among the best in the business in terms of aerodynamics, and particularly distinguish themselves from the competition in crosswinds. They achieve this level of aerodynamic efficiency while tipping the scales at just 1085g per pair and meeting or exceeding industry standards for wheel strength, rigidity and durability. This means that you can choose Mad Fiber wheels when you need the best performance on a day with big climbs – and not have any drop off in aerodynamic performance. It means you can choose Mad Fiber wheels for the flattest, fastest, windiest days – and not pay a price in added weight. And it means you can use them with confidence – even on rough roads

– without worrying about rider weight restrictions.
Specifications:
Weight: 1085g
Tires: tubular
Freehub body: Shimano 9/10 or Campagnolo 9/10 speed
Included: Skewers, cork brake shoes, wheel bags, valve extenders
Warranty: 4 years
Crash replacement program: 4 years
MSRP: $2599
MadFiber.com
Freehub body
Made in Petaluma, CA by White Industries (http://www.whiteind.com), titanium freehub bodies are a key component of our wheels. Lighter than steel, and more durable than aluminum (no notching from the cogs), titanium may be the perfect freehub material. A three pawl/24 tooth ratchet mechanism strikes the right balance between durability, strength and quickness of engagement. Including the 15mm cro-moly axle (steelremains an exceptional material choice for delivering strength and stiffness when space is limited – like inside a hubshell), White Industries delivers a freehub and axle assembly that makes an excellent, highquality, high-performance complement to the Mad Fiber carbon wheels. It will serve you well for years to come.

Accessories
Included with every set of wheels:
Brake Shoes: A perfect selection for use with carbon brake surfaces, cork brake shoes deliver excellent stopping power and superior durability compared to standard brake pads because of their resistance to damage caused at high temperatures.
Quick releases: Significantly lighter than most internal quick release cam designs, and significantly smoother in operation than most external cam designs, the quick releases included with your Mad Fiber road wheels are anything but me-too/insert-brand-name-here cheap QRs. Lightweight, effective, elegant design means you don’t have to rush out to buy new QRs to go with your wheelset.

About Carbon optimized design:
From the outset, the goal for Mad Fiber has been to fully realize the potential of carbon fiber in a bicycle wheel by matching advanced aerospace technology and production practices with decades of bicycle wheel building and design experience. To accomplish that, we had to ask, what is the best way to apply carbon to the wheel building process? Should we follow what has come before, and simply use carbon to emulate structures (extruded rims, forged spokes, threaded nipples) that have been optimized to be made of metal? Or should we go a different way and develop new techniques to get the most out of carbon fiber’s superior properties? The answer is obvious, no? To be successful, we had to do two key things, both of them part of our patent pending design and manufacturing process:
1) Build our carbon rims in a way that facilitates consistency of production and performance of final
product rather than striving to replicate extruded metal rims. Mad Fiber rims are built from three distinct pieces (the two sidewalls and the tire seat). As opposed to using a manufacturing system of bladders and molds to emulate an extruded metal rim, this enables exceptional control of the carbon manufacturing process, minimizing voids and eliminating the use of excess resin, resulting in increased strength and decreased weight.
2) Use carbon spokes, built and connected to both hub and rim in a way that maximizes the benefit of carbon rather than using or simulating metal spokes. There’s an awful lot of talk in the market about making (and reinforcing) spoke holes in carbon rims. We’ve seen carbon rims drilled just like traditional aluminum rims. We’ve seen carbon rims with the holes molded into the rim (with reinforcing fibers placed around the openings). And we’ve seen threaded inserts riveted into drilled holes to at once reinforce them and allow the use of externally threaded spoke nipples.
What’s it all mean? To us, it’s clear: using traditional spokes and nipples with carbon rims is an imperfect proposition. Creating a hole in the rim weakens the rim right at the point where the spokes and nipples apply a stress concentration. So we went a different way. We bond wide carbon spokes to both the rim walls and the flanges. This eliminates the issue of spoke hole drilling/reinforcing, and it spreads wheel loads over a broad area, increasing strength and aerodynamic benefit while decreasing weight.

So, no threads, right? Great. But that leaves the question of how to tension the wheel. Because anyone who has ever ridden a wheel that works with the spokes in compression understands: tensioned wheels feel better and deliver more strength for a given weight.
To understand the solution, you’ve got to think back to your high school trigonometry class. Imagine a line drawn from the rim straight to the center of the hub body. Now imagine a line drawn from the rim center to the hub flange. It’s a longer distance to the hub flange than it is to the hub center, right?
The spokes are bonded to the rim walls and hub flanges before the flanges are fixed to the hub body. This means that their un-tensioned lengths correspond to the distance from the rim to the hub center. Then all of the parts are placed in a fixture that allows us to precisely move the flanges to the outside of the hub body and bond them in place, simultaneously tensioning the wheel as the spokes are pulled into the position that requires them to cover a longer distance.
By considering all of the demands on the spokes and wheels: requisite tension to produce the desired strength and ride feel; spoke length and flange spacing dimensions to produce this tension; and optimal flange spacing for aerodynamics, we were able to create a wheel with the desired characteristics and do it in a way that comes out of the jig perfectly straight – and never goes out of true. That the same wheel approaches or exceeds the strength, aerodynamic and weight standards set by the industry’s best offerings in each category? That’s the result of carbon-optimized design. The difference between using carbon to emulate parts originally made of metal and instead, designing parts from the beginning to take advantage of carbon’s superior properties.
About strength and durability: Built to last

How many times have you seen a product with amazing specifications come to market only to have a rider weight limit that restricts its availability to just the smallest guys out there? On one hand, we love the idea of product customized to the individual rider, and on the other, we have to ask, “but what about everyone else?” So maybe you see some custom options from us in the future. But let’s talk about now: Mad Fiber road wheels, at just 1085g per pair, meet or exceed every industry standard test, and other tests that we have developed on our own. For example:
Wheel fatigue tests: Mad Fiber road wheels pass both the DIN and CEN standardized tests for wheel durability, as well as a third test, commonly run by a prominent US bike manufacturer, that is thee times more rigorous than the others.
Lateral strength: Mad Fiber road wheels surpass the CEN TC333 2002, test 4.10.2 standard, holding up (with no deformation) to a 56lb load applied for 60 seconds.
Lateral rigidity: Mad Fiber road wheels pass the Rinard side force test, which defines an acceptable range of deflection with a 25lb load applied to the wheel as a way of quantifying lateral stability as it relates to handling.
Radial strength: Mad Fiber road wheels can support over 600lbs static load – exceeding the common industry standard.
Brake heat stability: By heating our wheels to over 250 degrees while simultaneously applying a vertical load, we were able to validate their structural integrity under simultation of a worst-case scenario (dragging the brakes for an extremely long period on a sustained, steep descent).
Overall thermal stability: Mad Fiber road wheels resin and bonding show now ill effects after exposure to temperatures of over 220degrees F for 120 hours.
So what does it all mean? No Rider Weight Restriction. (and really durable wheels.)

Die Speichen sind ja sowas von schlecht gemacht. Überhaupt nicht materialgerecht. Massig per Kleber gefügte Verbindungen.

Naja, wie bei LW wäre es sinnvoller, das stimmt, ansonsten ist Kleben ja nicht so schlimm, wenn richtig gemacht. Allerdings sehen die Nabenflansche wie auch die Speichen in den Klebebereichen auf den Fotos auf der HP sehr glatt aus, hoffentlich arbeiten in der Serie mit Abreißgewebe...

Und zumindest vorn hätte man Speichen und die Flanschhülse schön in einem Stück fertigen können.
Hinten wahrscheinlich auch.

Was ich mutig finde ist: "No Rider Weight Restriction", gerade in Amiland. Wenn das ein 220kg Triplewhoppermann ernst nimmt und damit den Stelvio runterbremst oder Pavestücke bergab mit 60 anfährt....

Nuja, ich möchte jedenfalls die Klage in Amiland nicht am Hals haben...:rolleyes:

Das waren ganz feine Teile. Rollten sehr gut. Und richtig stabil. Ich bin so einen Satz mind. 30'000 km gefahren ohne das kleinste Problem.
