Ultima Carbon SL28 - Disc Brake Wheels

Rim depth plays a huge part in the ride dynamics of a wheel. The shallower 28mm carbon rims used in our Ultima SL28 wheels are specifically designed for maximum vertical compliance which creates a smoother, more comfortable and faster ride, especially on coarse road sections.

At 1417 grams, the SL28's are the lightest carbon wheels we make. Light weight wheels accelerate quicker with less effort and respond faster to direction changes. This makes your bike feel lighter, more agile and responsive.

Wheel Specifications

All Craftworx wheels are hand built to order. We use high quality Double Butted Stainless Steel spokes to to create the perfect balance between even spoke tension and ultimate strength without adding unnecessary weight.

The wheels are tubeless ready. This means you can run tubeless tyres or clincher tyres (with tubes).

These wheels are optimised for 28mm tyres but you can easily use down to 23mm tyres and when clearance allows tyres up to 32mm will also fit on these wheels.

Another great looking set of wheels

Bit early for a review but high expectations. This will be my second pair of Ultima hoops. Previous wheels still going well after quite a few years. The new rims mark my transition to disc brakes so can't wait to get the bike built and try out the latest set. Look great out of the box so far and expect the performance to match based on past experience.

Amazing wheels

Have always wanted a proper set of carbon wheels but hard to justify the pretty steep prices. Big thanks (& congrats) to the Craftworx team for the 10th anniversary sale for the excuse to take the plunge.
Boy I wish I'd gotten them much sooner, they are amazing in so many ways. Even in the delivery box they're lighter than my lightest current wheelset :)
The bike is now so much more responsive, it just leaps forward and I find myself changing up to an easier gear much less often. Braking performance is remarkable, loads of modulation & power - better than my alum wheels which was a surprise.
Most remarkable though is the increased comfort - I actually checked tyre pressures. Was not expecting that from 50mm deep aero wheels.
Abosutely perfect build quality (of course) & always a pleasure to deal with the Craftworx crew.
Certainly the most lavish bike purchase I've made but worth every cent.
Thanks so much Mark & the team at Craftworx

So Far So Brilliant!

Very Very VERY HAPPY with these wheels even though it's earlydays. Upgrading from stock wheels on my BMC these have made a huge difference.
Love the smooth rolling of these wheels the sound coming out of my SL38's and the look cool to! Customer service and assistance is second to none as well. Discussing with the Craftworx team prior to purchase made the decision so much easier.

Ultima SL28 - positive, light and lively

Super impressed with the new Craftworx wheel set. The SL28s have added a light and lively feel to the bike, particularly under acceleration. They feel great on steeper climbs and respond very positively to each pedal stroke. The ride seems smoother and more sophisticated too, they seem to have added a nice touch of controlled and sympathetic damping to the ride quality. TLDR: great wheel set, would buy again!
