Looking to go faster?  Then look no further.

At 1455 grams, the Craftworx Ultima Aero SL is the new standard for speed on two wheels. Weʼve distilled the very essence of riding fast into pure carbon fiber pleasure without making a single compromise on stiffness or durability.

Whether youʼre a budding amateur, a hardened rouleur, or a rider with a deep affinity for all-day soul rides in the mountains, the Ultima Aero SL is built to deliver effortless aerodynamics and best-in-class power transfer.
The 50mm deep wheel generates and maintains airflow attachment, reducing drag and thereby keeping your speeds higher for longer.

With low weight, and bomber durability, the Ultima C50 Aero SL achieves a rare trifecta of qualities that admit them to the hallowed pantheon of truly versatile wheelsets. Climb, descend, or prowl the flats with confidence knowing that youʼre ready for whatever the road can throw at you.

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.

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.

Our proprietary braking system resists heat build up.

Ultima Aero SL carbon wheels resist heat build up when youʼre flying downhill and apply the brakes.

Regardless of conditions, the Ultima Aero SL stop on a dime. Weʼve specially developed our proprietary carbon rim and brake pad system so that, when paired, create the perfect match.
 

Real Life Testing Conditions

 
Over a four-month training period in the Alps, world cup triathlete Emma Jackson barely scratched the surface of her Ultima Aero SL wheelset. All told, brake pad wear came in at a mere 55%, and there was zero wear on the carbon rims.
