RACE PROVEN, UCI APPROVED WHEELS.

All Craftworx carbon wheels pass UCI testing requirements. Not all of us race but it's nice to know you can have complete confidence that the wheels underneath you meet their stringent quality standards.

Confidence

Braking Performance

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

Bryan's Baum

'The finish quality is awesome, wheel wizard Mark gets an elephant stamp for his attention to detail! Needless to say, the bling factor was off the Richter scale with the bunch! (mixing it with Enve's, Zipps etc.)'

Great experience end to end, completely recommended

I purchased a set of Ultima 38 Aero SL, both the product itself and the help I received were superlative.

I was interested in the 50s and the 38s, I asked about a mixed set, was told it'd be ok. After a nice yarn with Mark, it was clear that I needed a set of 38s, not a mixed 38/50. Mark didn't push me either way, just offered opinion and advice freely, which made it a very pleasant experience unlike when you go to a big box store and they simply try to push the most expensive item onto you ASAP.

I was offered a customized red set for which Mark sent the photos within 5 minutes of the call. Within an hour of putting in my order, they had it packed away and sent to the post office. I received it within a week, and had a question for which I sent an email. I got a phone call back within 1hr of my email. You just can't this kind of service anywhere else!

The wheels themselves are amazing. I've put them onto an old Cervelo Team Soloist, and it flies when my legs to their part. :) Compared to a set of Bontrager Aeolus 3s I have on my other bike, these are in no way inferior - I'd happily ride these against any other wheel on the market. I will be recommending these to my mates when they start getting the upgrade itch.

Thanks guys.

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!
