INTENDED USE: Our Ultimate Aero disc-brake ROAD wheelset. Specified for maximal speed and acceleration in road racing, triathlon, sportives and club chain-gangs.
Combining all the knowledge and experience we've built up over the past 20 years. The 50FW’s combine low weights, with maximal aero gains, married to the latest rim profiles (to get the most from modern tyre systems). And on top of all this: the FILAMENT-WINDING construction makes them prodigiously strong. Rated in fact to 125kg.
We designed them specifically to get the best out of the new generation clincher and tubeless tyres. At 26mm wide the rims are optimised for seamless interfacing to road tyres in the 25 to 32mm range (but they will also take wider tyres such as the new breed of CX tubeless too!)
Weighing in from as little as 1535 grams, they are rated for riders up to 125kg. That’s very light and strong for a 26mm wide (19mm internal), fully tubeless/clincher compatible wheelset.
The 50FW's are focused on max aero gains, and are slightly narrower than our 34FW (34mm deep), 46FW (46mm deep), and 52FW (52mm deep) Carbon Aerodisc wheels.
Our premium full-carbon wheelset utilises patented “filament-wound”, robotic-built, ultra-high temperature K1-50FW rims. Available in stunning matte black finish with choice of decal colours.
Sounds fancy: Filament winding technology is an automated method which has revolutionised rim consistency in the manufacture of full carbon wheels. Each rim is made from single carbon filaments precisely wound into shape - with no joints or junctions - this enables a uniformity and strength that builds into the roundest and most balanced wheels possible.
This extends into the quality control stages where each and every rim is X-Rayed to ensure uniformity and compliance.
Your wheels will be Handbuilt to order here in the uk by Andy Morgan, owner and founder of k1 wheels. (Exact current build times are shown above).
Offered With Full Warranty and professional mechanic support in-house.
This is the newest of our K1 carbon wheelsets. At 26mm wide, with a full carbon u-shaped asymmetric rim profile (to perfectly balance spoke tensions) - it is aimed at those riders who prefer an ultra-modern wider rimmed wheelset.
Weight wise: When specced with BITEX futureproofed hubs and the wonderfully aero and light PSR1422 spokes.... They come in at 1490 grams a pair.
The new generation wide rims are perfectly suited to disc-brake riding. They are very strong, yet very light and very forgiving to ride. Aimed primarily at road riders using 25mm to 32mm tyres. Though they will take tyres up to 60mm and beyond! Perfect for running tyres at lower pressure and arguably more aerodynamic and faster rolling than traditional hoops!
It's an incredibly fast-moving time for road disc systems at the moment with lots of competing standards for Axle types and frame fitting methods and for rotor fastening.
The K1-50FW’s are hand built to order and are available for the whole wide range of modern axle and rotor fitment systems. Whatever your frame needs we can configure these wheels to your bike. And even if you change your bike - the hubs are all simply convertible to all the other axles standards! We think that's massively important as it future-proofs your wheels! (no one wants to be left with the betamax of hub types and obsolete wheels!)
Or just drop us a line If you don't know what system your bike has (you won't be alone - many people very understandably don't know, they just want to ride their bike after all!)
AXLES : We can configure your wheel axles to meet your frame requirements. So whether you have standard quick release or the more modern "thru-axle" setup, or whether you have 135mm or 142 mm rear spacing, we can supply them ready-to-roll!
ROTOR / HUB FITMENT : We use the superbly versatile Miche and Bitex 6-drive hubs. WE NOW ALSO OFFER THE ULTIMATE IN PERFORMANCE HUBS: The DTSwiss 350 and 240 series in both Centerlock and 6-Bolt flavours. Weights below for C/Lock. Add approx 100 grams for 6-bolt.

After looking for several months for a set of carbon aero tubeless wheels I finally decided to give Andy a call. Very professional & knowledgable I decided to order a set with CXray spokes & bitex centre lock. When you think a set of Mavic’s or Zipp of similar speck is nearly double the price it’s a no brainier. Arrived well packaged. After riding several hundred miles I’m really pleased & best of my bike looks great & had lots of compliments
I gained 1 mile extra per 30 minutes of riding. I am still new to the sport only 450ish miles on the new bike. The ride is so amazing its like riding on cotton. I also had to adjust the seat again, but overall 8.92 miles in 30 minutes. That was with a pretty stiff 20ish mile an hour head wind a good part of the ride.
Will do a few shots of scenery of where I ride this weekend and thanks so much for the rims, they are excuse the language but f*****g amazing as far as softness, the cross winds do move the bike when its breezy for sure, the rolling resistance @ 60 lbs is the sweet spot at least for me. I think I could run 55, but will stay at 60 for the time. I have posted you all over facebook and I have a few overseas friends who might order.
What a fantastic set of wheels. Built with my own hubs which are my go to hubs for MTB and road. The build quality and finish is exceptional and the service I had deciding on the build was expertly given. They finish off the look and performance of my Kinesis gf-ti build and I couldn't be more pleased.
Can't fault Andy's service. After a good deal of online research, I dropped Andy a line and within 30mins he called me to discuss. He then did a load of research on my bike and independently identified that the manufacturer had published an inaccurate measurement, and made allowances for this in the build. Had he not done this due diligence (or I had chosen an off the peg set from elsewhere) I'd have bought wheels that didn't fit. I went for six bolt Bitex hubs and CXRay spokes. They're light, spin beautifully (a genuine, noticeable gain on downhills and flats), stiff in the climbs, great value and look the business. Highly recommended.
