INTENDED USE: Combining superb aerodynamic gains with superb build quality, and achieving weights as low as 1295 grams - This is the latest version of our Premium “Ultimate” full carbon 40mm deep Sportive/Triathlon/TT aero wheelset.
Aimed at riders who want all the fantastic benefits of quality carbon without going too deep. This maybe because you are a nervous descender worried about crosswinds - or simply that you value weight-saving as much as aero gains.
Incorporating the latest carbon FILAMENT WOUND (FW) technology to create a fantastic ride performance, with superb braking, cushioning, cross-wind handling and heat dissipation.
This wheelset is ideal for Road, Sportives and longer distance and hillier triathlon and time trial courses. They are "2-Way Fit", Meaning they are designed for both clincher tyres and the new generation of tubeless tyres.
Standard spec weight is 1395 GRAMS grams (see below). When specced with the wonderfully aero and light CXray spokes/Bitex Superlight hubs.... They come in at 1295 Grams a PAIR!! And they are also "tubeless ready"! And these are tough rims rated to 120kg riders.
Your wheels will be hand built to order here in the UK by Andy Morgan, owner and founder of k1 wheels. (Current build times are shown above).
Our premium full-carbon wheelset utilises patented “filament-wound”, robotic-built, ultra-high temperature K1-40FW rims.
Sounds fancy: Filament winding technology is an automated method which has revolutionised rim consistency in the manufacture of full carbon wheels. Made from single carbon filaments - the manufacturing process enables precise control of every step - resulting in the roundest, strongest, lightest wheel combinations.
This level of precision and care extends throughout the entire quality control process - with each and every rim X-Rayed for structural uniformity and compliance.
Not only does this make for stronger, longer lasting wheels - but also the nature of the "winding process" facilitates another new technology that massively increases braking capability - especially at high temperatures.
The new 2020 model is also lighter than last years. Again this is due to the precise control that filament winding enables.
The filament winding process enables the injection of a patented ultra heat resistant resin - directly into the carbon filaments - whilst the rim is built. This means the rim's braking surface is fully impregnated with resin during manufacture - rather than a braking surface being added to the surface of the rim post-production.
This makes for better braking - especially on longer descents. These rims have their braking performance tested up to 250 degrees celcius. This is 20 degrees higher than our previous rims - and as high as any top-end rims on the market.
NOTE: Whilst rim tech has leapt forward in recent years - there are still some major things users of carbon wheels need to know! Please do read our page on safe braking and care for your carbon wheels HERE
Handbuilt in the K1 workshop in Gloucestershire. We combine traditional wheel-building techniques with cutting edge technology. And the world of carbon wheel-tech moves endlessly forward! Exciting times!
YOU CAN RUN THESE WHEELS WITH CLINCHERS OR WITH TUBELESS TYRES: IF YOU WANT US TO SUPPLY AND FIT NEW GENERATION TUBELESS TYRES WE CAN DO THIS FOR YOU (Includes tyres/tapes/sealant/valves and extenders - so that you're ready to ride them straight out of the box. CLICK HERE if you'd like to purchase this option!
Ideal for tyres from 25c right up to 30c and beyond. Perfect for running tyres at lower pressure and arguably more aerodynamic and faster rolling than traditional hoops.
The rim width debate will continue to rage and rage. What with rims now available from 19 mm right through to 28mm wide. We've decided to go straight down the middle and our rims are Significantly wider than old-school rims but not crazy wide. We think that's the best place to be!
