Wondering how we achieve such a high standard? We do it one handbuilt wheel at a time in our Brisbane workshop. Our craft is building the best wheelsets available anywhere. Everything we create is built to meticulous standards that are constantly improved through marginal gains. With an industry-leading quality control practice in place, we are on the never-ending quest for wheel-building perfection.
Craftworx Ultima Carbon
Lightweight, aero and fast
The Ultima Aero SL carbon wheelset is equally at home racing UCI calendar bikes races and local after work group rides. Thatʼs because weʼve built them to the discerning standards of professionals like world-class triathlete Emma Jackson, who rode our Ultima Carbon wheels to two World Cup race podiums.
With invaluable feedback like hers, weʼve conclusively built the Ultima Aero SL wheelset to manufacturing standards that meet and exceed UCI testing requirements.
There are a lot of technical aspects to building the perfect wheel, and although this skill can be acquired overtime by most capable mechanics, we have mastered it. We are the Wheel Experts.
Every Craftworx Custom Hand Built Wheel is crafted with extreme care and precision. We know that to achieve the ride dynamics, durability and performance that we expect, every stage must be taken carefully to ensure all components are built to our exacting standards.
Using the very best materials and a minimalistic design, we have engineered our Ultima SL hubs to weigh less than most high end rear hubs. All this with out sacrificing performance and durability.
SL hubs are available in black or blue
SRAM XDR hubs are available
The Ultima Carbon C38 Aero SL uses our latest 25mm wide rim profile. Perfectly suited to 25mm tyres allowing you to maximise the performance of your tyres. The shape of the tyre on a wider rim increases speed, improves handling and gives you a more comfortable, smoother ride.
In wet or dry conditions, Ultima carbon wheels stop with ease. Our carbon rims and brake pads have been developed to resist heat build up ( the biggest single reason why carbon rims “melt or delaminate” under prolonged braking ).
Want proof, Australian Triathlete Emma Jackson, 4 months training in European Alps. 6,875km. Total elevation gain 76,200m. Longest descent 20 minutes. End result, zero wear on carbon rims, brake pad wear at 55%.
“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
