Craftworx Ultima C28
Carbon Road Wheel Set

UCI Approved

The Ultima SL is the lightest wheel we make. At only 1290 grams it is going to get you to the top quicker and you can ride them everyday.

A wheel set we have only done by special request is now part of our range. Taking our very light C28 carbon rim and giving it the full treatment.

Our mega light Ultima SL hubs (only 247 grams a pair), DT Swiss Aerolight spokes renowned for their strength and very low weight and alloy nipples build a wheel set that weighs only 1290 grams. And make no mistake, these wheels not only will get you up the hill quicker, they are solid enough to be used every day!

Supplied with specially formulated brake pads giving you loads of stopping power in all riding conditions.

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.

Ideally suited for riders between 40 and 85kg

RACE PROVEN, UCI APPROVED CARBON ROAD WHEELS - Designed to perform at an elite level, yet affordable to all riders. No fake promises, just results. World Class Triathlete Emma Jackson rode our Ultima C28 Carbon wheels to 2 World Cup Race Podiums!

HIGH PERFORMANCE, LOW TEMPERATURE, BRAKING SURFACE - 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, 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%.

Customer Reviews

Based on 21 reviews
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.


Performance, Comfort, Speed


Purchased these wheels just recently after lengthy research and they lived up to high expectations, Previous reviews are right on the money, awesome wheels and service

- Lucy about her Ultima Alloy Wheels.

I think perform as well as well as my Enve’s which I paid double the money for the year before I found Craftworx. The braking surface and performance is excellent and one feels totally confident.

- Geoff J about his Ultima Blade 50 Carbon Wheels.

These are seriously good wheels. I thought the previous wheels I bought from Craftworx were good, and they were, but these are noticeably better. Lighter, smoother, stronger and faster. I just love 'em. They also look spectacular on the bike and have given it a unique look. They were noticed immediately by riders in the group.

- Kon about Ultima "Limited Edition" Alloy Wheels.

Fast delivery, well packaged. First impressions "Wow, they look fantastic". First ride, 1525m in elevation up Mt Buffalo (N.E Vic), super smooth, light and stiff, exactly what I wanted.

- Mark Staley about his Ultima Aero Alloy Wheels.
