Kinetic-One “K1-50FW ULTIMATE” Carbon Wheelset




INTENDED USE: With weights as low as 1375 grams - This is the latest version of our Premium “Ultimate” full carbon 50mm deep aero 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 spec weight is 1470 GRAMS grams (see below). When specced with the wonderfully aero and light CXray spokes/Bitex Superlight hubs.... They come in at  1375  Grams a PAIR!! And they are also "tubeless ready"! 

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 K1-50FW 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!

Great set of strong, lightweight wheels. Superb customer service, satisfaction guaranteed, beyond any imagination. Totally satisfied.

Matt Wilson - United Kingdom

Just wanted to say thanks for the wheels. They're great. Lightweight, strong and true. Took them on the club chaingang and had lots of people asking where they're from so hopefully put a few more customers your way. Attached a photo of them on my old btwin Mach 740. Forgot to mention, superb value for money (see gallery)

David Thomas - West Glam

I do love these wheels. It did take some serious soul-searching before i finally hit the button and went for wider rims. (I used to race on 16mm rims back in olden-times!) I did have a few problems with setup as My Tektro brake calipers could not really handle the width of the rim. As soon as I put some Shimano brakes on all fine and I have not looked back - 28c tyres are so comfortable too. Brave new world!

Paul Bradley - Dublin, Ireland

I carried out a lot of research before deciding to purchase the K150 carbon wheels with 28mm wide tyres. I decided to go for lighter Sapim CRray on Bitex hubs, so they would be lighter than my existing wheel set. I have found a marked increase in speed on the flat using the same effort / power & down hill speed has increased also. Really like how they look. So all in all I'm very happy with my purchase at a very competitive price & would highly recommend these wheels to others.

Peter Chapman - SE 10

I bought these on recommendation from a friend. I've nothing to compare them with as they are my first and only (ever i suspect) pair of carbon wheels. I do know they make me go faster and make my bike look very nice. Being able to choose the finish colour is a very nice touch. Thank you.

Phil Gwilliam - Malvern

My carbon K1 50’s look & sound really cool - they seem as quick as £2k knight composites I have on another bike , accelerate & climb well & aren’t affected by crosswinds or the Ukrainian road conditions around The Malverns -the owner of Detour cycles Malvern was very complimentary- will send photo when I stop at a good photo opportunity & stop chasing times - thanks Phil

Barry Mooney - Glasgow

From start to finish dealing with Andy and Kinetic One Wheels has been amazing. Everything from contacting Andy to ask about different builds I was thinking about and what might be best for my type of riding, weight etc. It’s not an easy decision but I ended up going for the K150-ULTIMATE FULL CARBON wheels and I’m glad I did as the look and ride fantastic! The wheels were delivered quicker than Andy had actually told me but he also kept me up to date with the process and delivery. The wheels arrived boxed very securely and could not believe how light they were when I took them out the box. The only problem was it was December and had to wait until better weather as they were going on my “good” bike that doesn’t see rain haha! When I eventually got them on it was worth the wait. Not only do they look fantastic on the bike the go great also. From my first ride I was breaking PR’s on local hill climbs with ease and have continued to do so. This is my first set of carbon wheel so don’t have anything to compare it to but all I can say is they are fantastic! I would highly recommend Kinetic One wheels and Andy as a person couldn’t not do enough to help!

Thanks again Andy and I’ll definitely be back for wheels in the future 👍🏻

Dave Green - Midlands

Just wanted to drop you a line to say just how fantastic the wheels are proving to be. These wheels have certainly given me that little bit of extra speed enabling me to match the pace of some of the more “expensive aero” bikes on our group rides so a big thanks to Andy and his team.

Jordan - Cheltenham

Upgraded to these having previously used a Planet X tubular set and a Mavic Cosmic (with alloy braking surface) both around the same rim depth. The K1's have been a considerable upgrade for not much more cost. Andy talked me through spoke and hub options to create the right set up for the riding I do and taking into consideration rider attributes such as weight (for reference I am 67kg).

I have used these wheels on both my road bike for circuit races and TT bike for non-draft duathlon as well as a few training rides . I have been thoroughly impressed with the performance of the wheels so far (probably around 500km or riding in total). The 50mm depth make these really versatile as a go to set for racing, TT's or just making your bike look great on a club ride. They get up to speed quickly and the quality of the hubs mean they spin for an eternity, handling is great and has been tested in some less than ideal conditions at Odd Down and Castle Combe with the u-shaped profile seemingly helping with air flow compared to my previous Mavics. The braking has been consistent in both wet and dry conditions with the supplied brake blocks. It's great that you can select your own decals to match bike colours, I went for a subtle grey and black to allow transfer between bikes and a bit of a stealthy look.

Overall super impressed and would highly recommend.

Matt Clifford - Barwell

Great wheels, they look and feel great to ride. A great improvement on the standard wheels that came with the bike. Excellent communication and delivery information.
