INTENDED USE: This wheelset is aimed specifically at super-fast road riding and triathlon. Versatile enough also for time triallists - our all time bestseller!
The 55/65 offers an unparalleled balance between aerodynamics, low weight, and superb cross-wind handling. With its slightly deeper rear we also think it offers the best look on any bike!
It’s the latest addition to our Premium “Ultimate” full carbon range. Fully specced 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 bunch racing, sportives, Triathlons, Time Trials and fast leisure riding too. The most multi-use wheels we’ve ever made in fact.
They are "2-Way Fit", Meaning they are designed for both clincher tyres and the new generation of tubeless tyres.
The spec weight with our recommended Aerolight build is 1545 GRAMS.
If you want all out aero gains (for time trials or flatter tri's) then the AERO build version with full-on 3mm bladed spokes is the model to go for. Not as light but hubs custom drilled with full bladed spokes.
To combine the best of both worlds (weight saving and max aero) ..... go for our SUPERAEROLIGHT version - with the wonderfully aero and light PSR SL spokes/Bitex Superlight hubs.... These wheels come in at a tiny 1485 Grams a PAIR!!
Or if you absolutely must have it all: Then it can only be - the Ultimate version. Specced with the worlds most resilient and best engineered hubs.
Your wheels will be hand built to order here in the UK by Andy Morgan, owner and founder of k1 wheels. Turnaround time is most often 7-11 days. (current build times are shown at checkout).
Our premium full-carbon wheelset utilises patented “filament-wound”, robotic-built, ultra-high temperature rims.
Sounds fancy: Filament winding technology is an automated method which has revolutionised rim consistency in the manufacture of full carbon wheels. Made from a single carbon filament - 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 long hot 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
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 £133 (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!

Hi Andy, Just thought I’d drop you a line to say I love the wheels. Having now done a few miles on them, including a short time trial and a longer day out I can say that they are both fast and comfortable. I had been running Hunt aero aluminium rims (30mm deep), but your 50/60ish set if anything are less sensitive to crosswinds and feel loads more stable at speed. The pairing to the Conti tubeless tyres also works really well- really confidence inspiring in corners. Thanks for the great kit, I’ll be recommending your wheels to anyone who will listen!
Review: Spot on set of wheels. I use them in sprint tri''s right through to century sportives and they really feel like the right wheels gfor every job. you never feel you''re losing out. Again i guess that''s the aero and lightweight thing! Tough as old boots. i''ve given them a right lamping on our very knackered roads.
Review: I originally bought these as they looked like they''d go really well with the grey/black paintwork on my Trek Eqinox (I know thats a pathetic reason but there I''ve admitted it!) I''m not the most powerful rider and am very light. I was immediately surprised how much faster i went using these wheels - I suspect that being light has meant that when i''ve previously used aero wheels that any new aero gains have been cancelled out by the fact that the wheels have added more weight to the bike. These wheels are quite a lot lighter than my existing wheels and have deeper rims - So i''ve concluded that this is responsible for my improvement. I can''t think of any other explanation - by improvement I mean 19 seconds off my PB for 25 miles the first time i used them.
Review: 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 depth makes 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.
