INTENDED USE: With weights as low as 1345 grams - This is the latest version of our Premium “Ultimate” full carbon 50mm deep aero RIM BRAKE wheelset. Fully updated with 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, Triathlons, and also spot-on for Time Trials too. They are "2-Way Fit", Meaning they are designed for both clincher tyres and the new generation of tubeless tyres.
Standard build is our AEROLIGHT version with excellent Italian sealed hubs and class-leading PSR aero spikes.
For Maximum Aerodynamics, Lightness and All-Round Performance on a sensible budget: go for our standard SUPERAEROLIGHT build version (with the wonderfully aero psr superlight spokes and Bitex Lightweight 'all-season' hubs). They come in at 1435 Grams a PAIR!!
- By using cxray spokes and Bitex's incredibly light (65 gram) front hub, we can save another 70 grams! That's our 1345 gram SUPERAEROLIGHT++ version.
Your wheels are hand built to order here in the UK by Andy Morgan, owner and founder of k1 wheels. (Will ship within 7 days of order).

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 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 230 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
Your wheels will be 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 TYRES FOR YOU... WE CAN DO JUST THAT. Then 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!
Offered With Full Warranty and professional mechanic support in-house.
