SOLD OUT: NEXT AVAILABLE END MAY 2021

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.

Weight is 1335 GRAMS grams with our recommended SUPERAEROLIGHT build version. (see below).

Or if you want the lightest possible build then our 1295 Grams SUPERAEROLIGHT++ build is spec'd with the wonderfully aero and light CXray spokes/Bitex Superlight hubs....  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.  

This new 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 leaped 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!

Not everyone who likes great equipment and an aero advantage can average in the 20+ mph range !

Age, hills and wind can all mean that half your ride can be under 20 and that's where these wheels don't give the feeling of a penalty below 17 or 18 mph like my Chinese wheels definitely do! My campag shimal's are good, £800 pounds good but the aero is not there for when the roads level out!

I actually burned my legs today as I rode the first 20 miles giving it a big effort (and with big grins on my face) I paid a bit for that coming back as there was all the climbing and a headwind .

So I was well under 20 for periods and the wheels still performed really well. Talking of wind, I know you said that there weren't big differences across rims for a given depth but other than the "suck" from a couple of big trucks I would say these FW40's behave very well in the wind. Hope this content is useful.
