INTENDED USE: This is our brand new deepest ever wheelset. Superb crosswind handling and Ideal for both shorter and longer Time Trials and Triathlons. This is our deepest wheelset and is for confident bike handlers only - to be used where speed and aerodynamics and WEIGHT SAVING are king. Also fab for road riding on calmer days!
EXPECTED JAN 2020
Weighing in at as little as 1890 grams for a 25.5mm wide, tubeless/clincher, deep aero wheelset makes them pretty special we feel.
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.
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).
The 90/90FW 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 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. 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 85mm semi-toroidal u-shaped rims are 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, and is designed of course to reduce drag to the minimum and give you every watt of power - and at superbly low weight. As little as 1890 grams a PAIR in its lightest build option.
Offered With Full 2 Year Warranty Plus A 14 Day "No Quibble Returns Policy" - If You're Not In Love With These Wheels The Moment You Get Them Just Send Them Back For A Refund Any Time Within 14 Days Of Receipt.
The 25.5mm wide 90FW's 's are built around our modern 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.
