The latest updated version of our tried and tested K1-42SL wheelset: Fully styled, faster rolling WITH NEW AMBROSIO SEALED BEARING HUBS. Or upgrade to the super-tough and ultra-low drag Miche Primato hubs. See data here
The paired nature of the drive and non drive spokes means that lateral forces are balanced more evenly than on a traditional spoked wheel (where the spokes alternate.) They are ideal for riders looking for a fast durable investment wheelset.
At 23mm wide they are wider by 3mm than last years model. This makes for a faster rolling wheel by minimising road contact. It also enables a far more comfortable and aerodynamically optimised tyre/rim intersection.
Your wheels have our signature all-black 'Graphite' finish for a really stealthy look. The graphite finish means the entire rim (including the braking surface) has a dark grey finish. You can choose our stealth/black/dark grey decals for a look as in the photo’s here. Or you can choose to have your wheels built with any of our 10 coloured decal options. Our Graphite coating is chemically bonded onto the alloy giving a penetration to a depth of up to 50 microns thick. (Compare this to the standard for most wheels of 10 micron depth). Not only does the finish look fantastic - it Increases wear life of rims and gives quicker braking.
Our experience is that when customers elect to buy wheels with a dark coated surface ... they do want it to last. The coating does of course eventually wear. Most riders are reporting several years before this happens . And when they at that point ... your K1 rims in terms of their ‘wear life’ are just like brand new standard alloy rims! Good all round!

I can honestly say that the wheels are amazing. The spin up very quick, very smooth and the hubs are very slick and quiet. Interestingly they are very predictable and hardly move when hit by a cross wind.
Overall very very happy and an image of them has been liked across the Ridley cycling Facebook page over 100 times and the guys from my cycling club think they are a great looking wheel set and all thought that they were carbon.
