£200 OFF: Kinetic-One “K1-42TL DUO” Deep Alloy wheelset



Quite simply the world’s first deep-section alloy Tubeless/Clincher wheels.

INTENDED USE: General road riding, TT's, shorter Tri's, and all-round ‘best bike bling!’ The 42TL Duo's are the new CLINCHER/TUBELESS version of our do-everything aero wheelset. If you're going to invest in one pair of wheels for a range of uses, then we think this is the one to go for.



 Aerodynamic, handbuilt by us, superbly smooth rolling, sealed bearings and very strong. They do look very nice too (please see our gallery!)


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).

Offered With Full 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 latest updated version of our tried and tested K1-42SL wheelset: Fully styled, faster rolling WITH NEW AMBROSIO SEALED BEARING HUBS. Or upgrade to the super-tough and ultra-low drag Miche Primato hubs. See data here

The hubs are laced with superb black PSR AERO spokes (for Maximal aero gains). The paired nature of the drive and non drive spokes means that lateral forces are balanced more evenly than on a traditional spoked wheel (where the spokes alternate.) They are ideal for riders looking for a fast durable investment wheelset.

At 23mm wide they are wider by 3mm than last years model. This makes for a faster rolling wheel by minimising road contact. It also enables a far more comfortable and aerodynamically optimised tyre/rim intersection.

Having used these wheels for a season of triathlons, I have nothing but positives for them! They look great great and I have had many of my triathlon clubmates enquiring about them.

I've used them for training and racing from sprints to 70.3 (and the Ballbuster Duathlon) and have been impressed with how well the wheels hold speed and and seen me smash my previous Strava segments (even when I haven't been pushing).

Having spent a lot of time searching the internet and reading hundreds of reviews, I'm so pleased I discovered Kinetic One: excellent personal service, quick delivery and brilliant wheels

SInce i weight in at 230lbs, i was nervous about buying K1-40S 40mm aero wheels due to the low spoke count compared to my normal wheels. In fact, my clubmates were taking bets of 0.5-50miles before i broke a spoke. I am happy to say that after nearly 600miles of small hills (cambridgeshire!!), chaingang rides in the dark and clubrides through the potholes of cambs, beds and northants, the wheels are strong as ever and no problems at all.

Do the wheels make me faster, difficult to say. Do the wheels make me feel faster.....DAMN right! Oh and they make a great noise freewheeling.....which i never do of course...ahem!

Great communications from Andy, rapid delivery and cracking looking wheels. I can safely say i am well happy at the moment. Hopefully, it will be a long time before i need to access the repair / maintenance aspect of the service.

I could not recommend these wheels strongly enough

Wheels: K1-42S Duo Stealth. Are there lighter wheels out there? Probably - in fact with admirable candour Andy makes the same point but at this price you will be doing extremely well to find anything better in terms of both looks and function. These wheels want to go and by crikey do they look the part. This is my second round of K1 wheels and I won''t be going anywhere else for the next set, though these look like they will check out long after I do. And a huge chapeau / thanks to Andy for getting them to me way ahead of schedule. You are an absolute star. Give this man your business - you will be very pleased you did.

I would just like to pass on my recommendation and appraisal of the wheels I bought Christmas last year. I have just completed the Brutal ironman event in and around Snowdonia. The wheels performed above and beyond my expectations . The speed I gained on the downhill parts of the course and the sheer quality of the build is fantastic, several fellow rides asked about the wheels . Big thumbs up they are great.
