INTENDED USE: This wheelset is ideal for both shorter and longer Time Trials and Triathlons. Where speed and aerodynamics and WEIGHT SAVING are king. Also fab for road riding on calmer days!
Weighing in at as little as 1765 grams for a 25.5mm wide, tubeless/clincher, super deep aero wheelset makes them pretty special we feel.
This is the brand new, lighter, slightly wider; Fully updated with the latest carbon FILAMENT WOUND (FW) technology to create fantastic braking and ride performance. Fully clincher/tubeless ready we hope you’ll agree that this stunning wheelset has it all.
RECOMMENDED BUILDS: The Aeroflow model - complete with ultra-low drag MICHE hubs: the lowest rolling resistance of any hubset Or for the lightest build go for the Superaerolight version Learn more>>>
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).
The 65/90FW deep wheelset is superbly aero, beautifully balanced, and reassuringly well constructed from top end Filament Wound carbon.
The introduction of brand new filament-wound fully robotic-built ultra-high temperature tech has revolutionised the production of carbon 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 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. Our FW 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 available.
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
YOU CAN RUN THESE WHEELS WITH CLINCHERS OR WITH TUBELESS TYRES: IF YOU WANT US TO SUPPLY AND FIT NEW GENERATION TUBELESS PRO 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.
The 65mm semi-toroidal u-shaped front wheel is both superbly aerodynamic and extremely light. (this is the advantage that full carbon offers) The rim shape gives it superb cross-wind handling characteristics too.
This is coupled with our ultra-deep rear 90mm deep rear - to minimise drag and give you every watt of power - and at superbly low weight.
Offered With Full Warranty and professional mechanic support in-house.
The 25.5mm wide 65/90FW's 's are built around our modern "semi U" shaped structural carbon semi-toroidal aero rim. designed to run best with 25c to 40c wide tyres. The rim is designed to cut through the air going forward, whilst maintaining a superb lateral integrity to cross-winds across a full range of wind "yaw" angles.
In terms of rim width we think we've really hit the sweet spot at just under 26mm mm wide. We carefully explored all of the many possible widths that aero wheels are being developed in. We developed and continually honed our own testing protocols to this effect - and critically we looked at a whole raft of practical issues too that many rim makers simply overlook. For example frame spacing: Yes its possible to go wider but at what point do wheels begin to compromise the frame. The last thing you want is to find that your carbon wheels rub your frame the moment you get out of the saddle! 25.5mm wide is in our view the best blend of performance and practical usability in our experience.

Hi Andy, Just wanted to give some feedback on the wheels! - seriously impressed with them! Raced a couple of weeks ago and had a great bike leg! Took 10+ minutes off my old 70.3 bike time. (2.18) Not all down to the wheels but they certainly helped. More impressed with how they handled in the wind! No issues or anything. They are great. Thanks for the top notch service! Seamus
I was looking for a nice set of wheels for my road and tt bike without the huge costs of popular brands, I wanted an all round wheelset for my road bike suitable for flats and hills, also a nice deep rimmed wheel for my tt bike, I spoke to andy on the phone and settled for the set ups that I'm very pleased with so far and looking forward to riding for the rest of the year and beyond, currently sharing front wheels between the two bikes at the moment but will be putting my order in for my front tt wheel very soon, these wheels ride as good if not better than much higher priced wheels I have used in the past and without a doubt feel very good quality wheels, with expert and friendly advice from andy I have recommended these wheels to others so don't waste your valuable bike funds cash on over the top priced wheels get these ordered to your spec you wont be disappointed
I have coveted a pair of k1 wheels for a couple of years, only just this year being in a position to get some, but this level caring for customers and the environment is mind blowing and confirms to me I have made the right choice.
