Quite simply... The world’s first and only deep-section Tubeless/clincher alloy wheelset!
INTENDED USE: Bunch races, time trial and Triathlon (from Sprint to IRONMAN distance.) This is our multi-functional custom built ALLOY aero wheelset. This is a super tough - super aero racing and training wheelset that is equally at home on Summer TT's and fast winter commutes!
It’s for riders who want all the aero benefits of carbon - but want to stick with a more robust material and also save a significant sum of money at the same time. Not the lightest wheels we do of course but an enduring best seller ... now with the added benefit of being tubeless ready
It seems inconceivable to us: There was not a single deep-alloy TUBELESS & CLINCHER READY wheelset available anywhere on the planet... yet the benefits and need for them is so self-evident. So, in keeping with our long experience of innovation in wheel design... we came up with our own wheels.
Fully clincher and tubeless ready they are 23mm wide externally and 17.5 internally. Fully performance optimised for 25c and 28c tyres (will also take a 23mm if you have frame clearance issues ... or if you are old skool!)
Super aero rims complimented by black aero bladed spokes. We offer a range of build options - to suit your budget, your weight and depending whether your focus is on ‘all out aero’, or on reducing weight... or on the sheer look of these wheels!
The rims are handmade for us in Northern Italy by craftsmen who we’ve worked with for almost 20 years.
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 get removed. Most riders are reporting a few years before this happens . And when they reach that point ... your K1 rims in terms of their ‘wear life’ are just like brand new standard alloy rims! Good all round!
WE RECCOMEND SOFT BRAKE BLOCKS LIKE SWISSSTOP YELLOWS. (We can supply these blocks with your order - see menu above)
