Craftworx Ultima Aero SL
Carbon Road Bike Wheelset

Our flagship aero carbon road wheels - 1423 grams of raw speed!

The benchmark for performance in aero carbon road wheels. SL stands for Super Light. We've shred every gram of excess weight without compromising on strength and durability.

The 38m deep front wheel improves stability in cross winds and on fast, technical descents. The 50mm deep rear wheel efficiently transfers power and maintains top end speeds for longer.

Long solo rides, fast bunch rides, racing, triathlons or anything else, these wheels will do the job... and do it FAST!!

Climb with ease and descend with confidence. Our specially developed brake pads give you loads of stopping power in all conditions.


OUR FLAGSHIP AERO CARBON ROAD WHEELS - These wheels take our amazing Ultima C50 Aero set to the next level.

  • Lower profile C38 front rim to reduce weight, improve handling and reduce effects of cross winds on the wheel. This results in quicker acceleration, easier directional change and a more stable ride.
  • Upgraded to our Craftworx Ultima SL hubs. At only 247 grams, these are one of the lightest hubs on the market. But unlike some 'lightweight' hubs that cut corners and leave things out, we have achived crazy low weights through better engineering, design and superior materials.
  • Upgraded to bladed spokes. Bladed spokes are butted (thinned out to reduce weight) and the flattened reducing their footprint in the air, therefore creating less drag. This also makes the spoke lighter and stronger - Win + Win!
  • Upgraded quick release skewers to our Titanium version for extra weight saving (only 16 grams, but every little bit counts!!)
  • Will I notice a difference you ask?? You betcha! As good as the Ultima C50's are, these are next level again!

The Result is a lighter and more responsive wheel set for riders who want greater performance.

Yes, it comes at a greater price, but the performance improvements are very noticable!


The 25mm wide carbon rim is perfect for running 23mm, 25mm and 28mm road tyres allowing you to fine tune ride comfort and road handling. Suited to riders 65-110kgs.

There is also a HD - Heavy Duty  version available for riders up to 125kg's

No excuses

I don't have any excuses any more, these wheels are light and stiff and roll true and forever. Its now down to my legs! Great to see a local wheel builder doing good things. Highly recommend buying direct rather than via numerous middlemen, result being the consumer ends up paying margin on margin.

Aero SL Carbon 38/50

Awesome set of wheels, buy right, buy local you won’t be disappointed.

Amazing in every aspect

Having had a discussion with Nathan it was established that the C28’s would be the most suitable Wheelset for my needs, and I am very pleased with the quality and performance. Remarkable build quality!

New wheels

Absolutely brilliant, smooth ride, really accelerate up hill, superb on corrugated dirt roads, great service

Great carbon wheel set

Great stiff and light wheel set. I wanted carbon rims to use daily not just in”special occasions/racing” situations. Good quality and very quiet.
