Craftworx Carbon Technology

Next Generation Carbon Technology & Performance

Craftworx ULTIMA carbon wheels offer the next generation in Carbon Wheel technology and performance.

Designed to give you a serious competitive edge, they offer the very latest in carbon materials and manufacturing know how creating a range of carbon wheels that go every bit as fast as they look.

The Craftworx brand is synonymous with quality, performance and value, so it was a given that our Carbon Road Wheels would uphold our three core values.

 "The focus at Craftworx, has always been ride quality. It's what makes our wheels special" "We were quietly confident we could compete with the big guys in the performance stakes."

"We were quietly confident we could compete with the big guys in the performance stakes."

We started off by researching what was already out there in the market and three things became obvious very early on.

1. The market is flooded with average quality carbon wheels.

2. Most of the carbon wheels were not as good as our alloy wheels

3. The wheels that were good were crazy expensive!

Our expertise and experience at that time was in Alloy technologies, so we set ourselves the task of learning about and understanding Carbon manufacturing processes and materials. The goal wasn't to become experts, that would take years.

What we needed to do was increase our knowledge and understanding to a level where we would be capable of finding the right manufacturer to partner ourselves with for this project.

During a trip to Interbike, the annual bike industry show in the USA, we had a chance meeting with Joseph. We liked Joseph from the start, he's a great guy, and the more we talked, the more certain we were; we had found the right guy for the job. Joseph's factories have been exclusively molding carbon products, both in and outside of the bike industry, for the better part of 30 years. Joseph was one of the original pioneers of carbon manufacturing in the sporting industry. His facilities are state of the art; the quality and attention to detail, second to none.

When we met Joseph, we already had solid idea of the rim designs we wanted to trial, so we immediately set to the task of producing and testing prototypes.

For 6 months we road tested the wheels, tuning and balancing the riding dynamics and responsiveness to the point where we were satisfied they would deliver the performance we, and our customers expect.

We're seriously impressed and very proud of the end result and we know you will be too.

optimised braking performance


Maximum Braking Efficiency

Our Ultima Carbon wheels were sent to the Brake Pad manufacturers Testing Facility in the US where they were put through a series of heat resistance and brake performance tests. The brake pads supplied with your wheels will ensure you have maximum braking efficiency and minimal heat build up, in both wet and dry conditions.

This company have developed nearly 300 different compounds for carbon wheels over the years, so we didn’t just want to ‘pick one’, or go with the same pad that everyone else uses. We want the best! The results are better that we could have ever hoped for and the feedback from riders is validation that all the effort and time that went into this process was worth it!

“Solid as a rock and no problems braking, which was my biggest concern.” Daniel from Melbourne with his C50’s

I was a bit worried about the braking performance of carbon rims but my concerns were put at ease on the first ride, not an issue, excellent braking performance” Mark from Melbourne with his Sprint SL’s

A set of the Ultima Carbon Brake Pads are included with every Craftworx Ultima Carbon rim brake wheel set and can be purchased separately. They are reasonably priced and far more durable than carbon brake pads tend to be!

To keep your warranty, you must use only Craftworx Ultima brake pads.

Dual carbon layer process (dlp)


Strengthening Fatigue Zones

Producing carbon wheels these days is a relatively simple process that can be done quite cheaply. There are countless examples out there; manufacturers using old technology and cheap carbon fibre to produce low cost carbon wheels. If you have a very tight budget, these wheels can be very appealing, as they typically look the part. Unfortunately, they often fail to meet even the most basic QA tests and brake performance tests.

Producing high quality performance carbon wheels is a different matter altogether. You have to know which carbon fibres to use, how to use them, where to use them and how best to blend them to achieve the optimal result. It is a very technical process that requires a high degree of precision engineering.

We applied the Dual Carbon Layering Process in the design and manufacture of our Ultima carbon rims. Using the DLP process, we blend high-modulus and mid-modulus carbon fibres to create more dynamically balanced wheels. We use hi-modulus carbon to increased stiffness and optimise overall weight. Mid-modulus carbon is applied to key areas of the rim, strengthening fatigue zones, increasing durability and enhancing ride comfort.

Exactly what type of carbon do we use? We'll keep that one a secret.

Noise reduction technology (nrt)


Smoother, Quieter Ride

One very noticeable difference when you compare Craftworx Carbon Wheels to most other carbon wheels on the road is the amount of noise (or lack there of) that our wheels generate.

No doubt, you have noticed how noisy many deep section carbon road wheels are compared to lower profile carbon and alloy wheels. Road noise resonates inside the hollow chamber of the carbon rims typically producing hollow rumbling, droning sounds.

Our Carbon Wheels use Noise Reduction Technology for a smoother, quieter ride. So quiet, the riders in front won’t know you are coming!



Competition Ready Wheels

To use a wheel set in the top level of competition, it has to be tested and approved by the UCI, cycling’s governing body. This is testing protocol to ensure that the wheels have the strength to withstand a reasonable impact in racing conditions. The test involves a wheel being subject to an impact from a weight dropped onto the bare wheel. The wheel must not only withstand this impact and not show any signs of damage, but also stay straight and round within certain tolerance.

All Craftworx Ultima Carbon wheels for rim brakes are UCI Approved.

This approval is also valid for triathlon competition so if you are competing in tri’s, your wheels must be approved.

Now you may not need UCI approval, but it is comforting to know that the wheels have been approved to compete at the sports highest level.

sprint sl & aero sl Profiles


Significant Handling Improvement

During testing, we rode a lot of wheels! One thing we found and what our customers experience is the negative effect a deeper front wheel can have on the control and handling in corners and especially on windier days. We did a lot of testing with shallower front wheels combined with a deeper rear wheel and the results were incredible.

As most of the rider weight is over the back wheel and a lot less is on the front, the deeper front wheels is more effected by the wind so simply by swapping to a smaller profile front dramatically reduced the instability without any noticeable impact on straight line speed and aerodynamics.

Plus the wheels gave a much more lively and agile feel so cornering and changing direction was far better with a smaller front wheel. All in all, a significant improvement in handling without any drawbacks.

We offer this option with our Sprint SL (38mm rear and 28mm front) and Aero SL (50mm rear and 38mm front) wheel sets that also get lighter weight Ultima SL hubs, aero bladed spokes and titanium quick release skewers

Reinforced Valve Hole


Key Stress Point Strengthening

Why do we reinforce around the valve hole?

This feature that has nothing to do with the way our wheels ride or handle. Reinforcing of the valve hole area strengthens a key stress point in the rim. When inflating tyres, the valve typically moves around, pushing up against the edge of the rim.

Over time, this repetitive action can stress and fracture the edge of the hole. To counteract this we re-engineered the valve hole area, adding additional carbon reinforcement.

Resin impregnated threads (RIT)


Carbon Optimisation

This is when carbon threads are impregnated with resin as they are extruded.

RIT mixes the carbon and resin at a specific rate enabling us to optimize the amount of carbon and resin used in our wheels and to ensure that it is spread evenly throughout the rim.

When our rim moulds are exposed to intense heat and pressure, the resin melts and spreads throughout the carbon layers. As the rim cools, the resin hardens to form a solid rim.

Expanding Foam technology (EFT)


Perfectly Balanced Rims

Why don’t we use air bag technology to form our carbon rims? Back in the day when dinosaurs roamed the earth… Yeah Ok, so I’m being a bit dramatic here. About 30 years ago, someone very clever, developed the air bag system for moulding carbon fibre and at the time it was ground breaking technology.

30 years on, many manufacturers still use this old technology. It’s a cost effective process for manufacturing cheaper carbon wheels and components where consistency of wall thickness and finish is not a priority.

The air bags often fuse with the carbon and get stuck inside the rim; they can also inflate unevenly resulting in uneven wall thicknesses. These in turn put the rim out of balance disrupting the flow of carbon, which in turn has the potential to cause week points and stress points in the rim, which can lead to fatigue and failure.

Expanding Foam Technology is the best way to form carbon fibre. I’m not going to share everything here but the basic concept is this. Prior to heating, a special type of expanding foam (no, you can’t buy it at the hardware) is placed inside the mould. As heat is applied, the foam evenly expands flattening the carbon sheets and pressing them against the outside of the mould. Because the foam does not react with carbon or resin it can be easily removed, leaving behind no residue.

This system produces perfectly formed, perfectly balanced rims, inside and out!

Seamless Transition technology (stt)


Enhanced Aerodynamics

The most common reason quoted by cyclists for buying carbon wheels is for improved aerodynamics and increased speed.

Our Seamless Transition Technology (SST) reduces wind drag and turbulence caused by air flowing over irregularities in the rims surface resulting in improved aerodynamics.

When you look at our wheels, you will notice that the braking surface and nose of the rim seamlessly flow from one to the other. Using SST enables us to integrate the braking surface with the rest of the rim creating a smooth seamless transition across the entire rim surface, producing less wind drag and increasing speed.

Optimising spoke holes


Improved Integrity & Durability

The angle the Spokes and Nipples connect with nose of the rim varies depending whether it is a front wheel, rear wheel, on the drive side or the non-drive side. These holes are drilled at precise angles to ensure no lateral stress is placed on the edge of the rim or the nipple, alleviating unnecessary stress on both the carbon rim edge and the nipple that protrudes through the hole.

The spoke hole area in the nose of the rim is significantly thicker compared to other sections of the rim; 4mm at the deepest point. We place additional carbon fibre in the nose section to reinforce key stress areas. This design has the additional benefit of assisting in distributing spoke tension load over a greater surface area improving the overall integrity and durability of our wheels.

Why are our carbon wheels hand built?


Hand Built Wheels Ride Better

"Since the beginning, our Craftworx Wheels have always been hand built. It's a big part of who we are and it's what we love doing."

Hand Building wheels, for us, is a passion; it's all about doing what we love. We started building wheels at a time when all wheels were hand built to order and even back then, it was an art that few mastered.

Quality hand built wheels ride better, they have a more dynamic feel to them and they are more reliable.

If you have ever owned at set of hand built wheels you will know what I am talking about but for those who haven’t, well you’ll just have to trust me on this one! Machines definitely have their place in our world but when it comes to performance bicycle wheels, Hand Built is the only way to go!
