2020 Kinetic-One K1-42TL Aero Disc Brake Wheelset.... World's Fastest Alloys??


Select Currency


Introducing  what we are sure is the worlds first fully clincher/tubeless compatible deep-section alloy disc wheelset.  With a superlative rim designed by us - here in the UK and hand-made for us by craftsmen in Loria Northern Italy - this has been several years in development. (we also have the rim brake equivalent in our alloy's section!)

It may also be the world's fastest Alloy rim.... we should wait till we've tunnel tested it against the Aforce AL33 |(the current acknowledged fastest rim .. but early track tests conducted by ourselves are pretty clear to us! (It does need verifying of course.. just very excited .. we must be more patient!)


INTENDED USE:  Road , Sportives, TT's and Tri's.  This is our mid-range TARMAC/GRAVEL FOCUSSED deep section alloy road disc wheelset for clincher tyres - Super-aero, tough and a beautiful matt black finish. And at only 1760 grams for the standard build version - It is extremely light for a full deep-section alloy wheelset.

K1 disc

In short: It looks like carbon, has the same aero-profile as deep-section carbon, weighs very similar to carbon - and rides more like carbon than any alloy wheel we’ve ever made. It is also tough as they come. It is also the only seriously deep alloy to be tubeless and clincher compatible..... AND .. It’s half the price of carbon!

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).


THIS IS OUR BRAND NEW MID-RANGE, 42mm Deep, DISC SPECIFIC AERO wheelset. Designed simply to bring pure aero benefit to your Disc equipped bike.

Light and tough enough for the hilliest and roughest of Sportives, And fast-accelerating enough for racing, and of course, aero enough to ensure that you gain every possible watt of drag reduction.

The k1-42TL AeroDisc is built around our class leading  deep aero alloy rim, with it's pure speed profiling and its stunning "Graphite" finish.

The rim has an external width of 24mm and an internal width of 18.6mm - making it perfectly optimised  for 25c/28c/32c tyres in terms of both performance and seamless aerodynamics.

We marry the rims to the hubs via top end Belgian SAPIM spokes, always the pro's choice! You can elect to have the superb aero PSR 1422 spokes  or upgrade to Sapim CX-Ray spokes for absolute aero gain. The CX-Ray is still the most aero spoke on the market and about the toughest spoke available too.


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.

These wheel are totally versatile and ready to work all the modern variants that different brands are working to

The K1-42TL AERO DISC's are handbuilt 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!)
Technical details below.

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 FITMENT : We use Bitex 6-Drive and DTSwiss  hubs (for Centerlock and 6-bolt rotor builds).  

Hand built in Gloucestershire, and utilising top quality build components. We carry spare hubs, bearings, and should you ever need one - spare spokes!

Great wheels, run true, solid, outstanding customer service and the wheels look immense!
Mark Harney - Yorkshire
Andy, the wheels are excellent and did me proud at the recent World Duathlon Championships. They also look nice on my Felt bike (much better than Ottawa last year). As I’m not at the top end of cycling (just yet!), they are affordable but durable at the same time. My bike times are now getting quicker and one day they hopefully match my run times (which is where my strength is within Duathlon and Triathlon). I’m hoping to go to the World Duathlon Championships.....

Was looking around for carbon wheels and then I saw these. They did a good selling job with what they wrote as I was a bit nervous about carbon wheel strength anyway - so it touched a nerve. I love these wheels. had them only 2 months so can't comment on long term durability yet - but they are still so true and really feel incredibly strong when riding them over bad roads etc. Bought them to race on but have to say that they are on my bike 24/7 already!

Wanted a strong set of aero wheels for our dreadful roads. Ability to go for a 28 rear spoking was a clincher for me. Took longer than they said they would to build (12 days so not bad but they did say 7 days). Wheels are really very good and attract admiring comments too. Stiff and fast.

I'm really impressed with the build quality of the wheels, on my first ride I went down a pothole heard a bang and thought i'd damaged the front wheel but to my surprise the wheel was fine with no damage. Once up to speed they roll very well and i'm sure as the season continues I will see an improvement on my personal best times. As stated previously I can't believe how well they roll, in group rides on descents i'm having to apply the brakes and freewheel while my friends are still pedalling. Overall i'm very happy with the wheels and offer great value for money.

Thought i'd update you as to the durability of your wheels, I hit a large pothole last night that blew the tyre straight away at around 30mph. The inner tube had 2 splits about 1 inch long in them.. the wheels are perfect not a mark or dent in them and still run perfectly true. Excellent wheels and can't fault them in anyway having covered 2500 miles.
