Next to the bike itself the purchase of wheels is usually the biggest cycling outlay. I’m glad to say I’ve no regrets. A chat with Nathan confirmed my choice of Ultima SL28s. Giddy up, these wheels surpassed my expectations.
Coming from a reasonable set of Fulcrum Zeros the difference was very noticeable. Climbing is improved and I was surprised how much improvement I gained with aero. I could not fault these wheels and I’ve given them a pretty good pounding so far.

I bought the SL38's about 5 months ago and they are fantastic. I did plenty of research and it has ended up being the best buy I have made to compliment my F8. True, responsive and stable. The service and advice from Mark and the team was equally enjoyable to deal with. If you are after a set of top end wheels I highly recommend you give Craftworx a try.

I purchased C38 SL aero tubeless wheels ready from Craftworx through my bike shop Spoke n sproket in Melbourne.
I have upgraded from Mavic overrated kysirium exalith Pro wheels which were very fast with noisy brakes. Enough about my problems. I took these wheels for a spin and they blew me away with scaryspeed and just had to hold the brake a little too slow down wasn't used to the scary speed I call it and smooth as silk with racing and braking performance 2nd to none and look modestly great. Money well spent and can't wait to ride them again. Mark and his team have so much passion in their field of wheel building and should be awarded with medals in my book. If the review was out of 10 I would give them 11. I can't stop rating these wheels. Mark and crew please keep up what your doing and get stronger with your passion.

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.
