Brand new for the 2022 season, our SL Ultra Disc Aero Wide range uses Next Generation Aero Wide Rims for improved speed, comfort and handling.

Aero Wing Spokes for the Ultimate in Aerodynamic Performance.


Our new Next Generation Aero Wide rims follow the trend for ever wider rims - increasing both speed and comfort.

Nowadays more and more people are choosing to ride wider tyres. 28mm has become the norm, with many people choosing to go wider still. Wider tyres mean lower rolling resistance as well as increased comfort. It makes sense to use rims that have been designed especially for this purpose But that’s not all - wider rims mean an improved tyre/rim interface - better airflow from tyre to rim. And that means they’re faster. And better able to handle tricky crosswinds.

Oh, and they’re light too - really light! When it comes to saving weight on a set of wheels, the rims are the place to start - this is where you feel the greatest benefit in speed and handling. Our wheels are significantly lighter than those of our competitors. 

This is because our rims are amongst the lightest available - not only do lighter rims improve acceleration and climbing performance - they also improve the handling and overall agility of the bike - in fact they bring the ride to life!


 Of course our rims are suitable for both tubeless tyres and clincher tyres with inner tubes – whichever you prefer. Although they're optimised for 28mm tyres you can happily run 25s or go the other way - all the way to 45mm if you fancy a bit of the rough stuff!


The SL Ultra uses extremely light straight pull hubs to reduce weight over our standard Ultra models. High end ABEC5 bearings promise increased smoothness and durability.

Freehubs are available for Shimano/Sram 8,9,10,11, 12 speed and Sram XDR 12 speed.

The standard axle set up for these wheels is 100/12 front and 142/12 rear Thru Axle seeing as that's the most popular by far. But if you need something different, whether it's quick release, 15mm fronts or whatever, just get in touch.

The standard set up is for Centerlock rotors - again it's by far the most popular, as well as the most flexible. If you want to fit 6 bolt rotors it's a simple case of using an adapter.


For 2022 we’ve introduced the Pillar Wing Spoke

Our wheels are already fast - to make them faster still we've upgraded our spokes to Pillar Wing spokes - the ultimate aerodynamic spokes.

Pillar Wing 20 spokes use a unique shape based on airfoil technology resulting in a faster, stiffer wheelset.

The diamond-like cross section provides aerodynamic advantages over standard bladed spokes in cross winds as well as head winds.

They're also lighter than our standard bladed spokes - saving around 20g per wheel set.

They still retain all of the advantages of the patented Pillar triple butted system - which reinforces the strength of the spoke right where it matters most.

The front wheel is laced 21 holes 2:1 (16:8)

The rear wheel is laced 21 holes 2:1 (8:16)

We've chosen to build them with Taper Groove Hex head nipples - self locking, allowing finer control than a square head nipple and providing extra spoke support over a standard nipple. Little things, but they all make a difference...


The rider weight limit on this wheel set is 125kg in total - that's rider plus bike and luggage.


Wheels are provided with tubeless rim tape fitted

    I bought these wheels as I was disappointed with the performance and weight of my Cervelo Caledonia 5. After 4 months riding with them, they have made an incredible difference, they are fast, light and responsive and have improved the bike’s characteristics immensely. Definitely recommended!
