SALE : Kinetic-One “K1-42TL DUO Graphite” Deep Alloy wheelset

Out of stock


​​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: with deep section wider rim and PSR Aero spokes as standard, Handbuilt by us -here in the UK. Superbly smooth rolling with low-drag 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. (current build times are shown above).

Offered With Full Warranty

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 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.

Your wheels have our signature all-black 'Graphite' finish for a really stealthy look. The graphite finish means the entire rim (including the braking surface) has a dark grey finish. You can choose our stealth/black/dark grey decals for a look as in the photo’s here. Or you can choose to have your wheels built with any of our 10 coloured decal options. Our Graphite coating is chemically bonded onto the alloy giving a penetration to a depth of up to 50 microns thick. (Compare this to the standard for most wheels of 10 micron depth). Not only does the finish look fantastic - it Increases wear life of rims and gives quicker braking.

Our experience is that when customers elect to buy wheels with a dark coated surface ... they do want it to last.
The coating does of course eventually wear. Most riders are reporting several  years before this happens . And when they at that point ... your K1 rims in terms of their ‘wear life’ are just like brand new standard alloy rims! Good all round!

Climbed Alp d'Huez twice and Col de la Croix de Fer in June this year on the 42 toughs. Not really climbing wheels i suppose as heavy but so am I :-D Had great confidence in them especially on the descents :-).

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!

This is my second set of wheels from Andy. The first set are over 6+ years old, still as good as when they arrived, absolutely bomb proof, look fantastic, roll extremely smoothly and very quick. They have carried me over numerous Ironman events and many sportives. I wanted some new wheels for my aero bike and after a long time looking at different makes I came back to Kinetic One. A right decision - I've been hugely impressed with the K1-42TL and I have made the right choice. If like my other set these will cope with all weather conditions, all distances and road surfaces. The new version are lighter and save me constantly switching wheels between bikes. As I get back into racing I will be coming back at a later point for a set of carbon wheels from Andy. Top service - thank you once again for a fantastic product offering superb value for money - plus they look stunning.
