IN STOCK:READY TO BUILD

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 1695 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:  

For the lightest build go for the Superaerolight++ version. For all round lightness/durability go for the standard 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 TYRES WE CAN DO THIS FOR YOU - 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.
