INTENDED USE: THE K1-42TL TOUGH WHEELSET IS A TRUE HIGH PERFORMANCE WHEELSET AIMED AT HEAVIER RIDERS (100-140kg) OR LIGHTER RIDERS WANTING A VERY STIFF AND ROBUST AERO WHEELSET. NOW WITH AERO SPOKES AS STANDARD!
IDEAL FOR ROAD RIDING, TIME TRIALLING, TRIATHLON, & EVEN FAST COMMUTING. AND NOW FOR 2020 THEY HAVE THE BENEFIT OF BEING THE WORLDS FIRST DEEP SECTION ALLOY TUBELESS & CLINCHER COMPATIBLE WHEELS.
It seems inconceivable to us: There was not a single deep-alloy TUBELESS READY wheelset available anywhere on the planet... yet the benefits and need for them is so self-evident. So, in keeping with our long experience of innovation in wheel design... we came up with our own wheels.
Fully clincher and tubeless ready they are 23mm wide externally and 17.5 internally. Fully performance optimised for 25c and 28c tyres (will also take a 23mm if you have frame clearance issues ... or if you are old skool!)
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 rationale is simple and we can't understand why no other brand has thought about the performance needs of heavier riders. Perhaps not surprising as they tend to assume all riders are 8 stone after all!
Put simply, heavier riders tend to squash wheels radially and ordinary wheels compress under continual loading. Quite literally they are not round. Not only does this weaken the spokes and rims and hubs but the extra continual effort that it takes to rotate a wheel as it constantly deforms and recovers is huge. Like having donuts for wheels! (see donut image above!)
The solution is simple and known by all good wheel builders. its just that the rationale has not been applied to performance aero wheels ... until now.
The wheels are designed by Kinetic-One founder Andy Morgan. 10 years ago Andy was a 16 stone 10 mile Time Triallist. He rode the prototype of these wheels to a to a 20:47 minute 10 mile time trial which, whilst it was pretty pleasing, it was not that surprising given he was a TT specialist. But we only really knew we were onto something when he rode them to a top 20 finish out of several thousand riders at the Dragon Ride. At 16 stone - this shows that with the right equipment, heavy riders can still fly up and down even the toughest climbs. (There he is posing in the image above!)
Since then we've honed and developed the concept into what has become the K142TL TOUGH wheelset . Applying all our knowledge of aero wheels and adding in the key concepts that impart strength above all else. And of course - the latest iteration of these wheels is tubeless-ready too. And again heavier riders gain enormously (compared to lighter riders) from the reduced rolling resistance of tubeless.
So what do we mean when we say 'the solution is simple and known by all good wheel builders?':
Well, There are 6 elements that make a wheel stiff and hence round and true under load: Rim depth / rim strength / number of spokes / bracing angle / spoke gauge / lacing pattern. The decision to maximise the stiffness of each of these elements was the simple logic behind the 42TL Tough wheels. That and using very strong components that don't add surplus weight.
Our super tough deep rims and high spoke numbers are the key to stiffness. Our 28 spoked "paired / 2-Cross" pattern reinforces this further and holds the wheels true under heavy lateral loads (the spokes from each pair pull together at the same point on the rim at exactly the same time - one from each side of the wheel and this balances the lateral forces). This is much more effective at keeping a wheel laterally true under load than a traditional spoke pattern (where the spokes are equidistantly separated and alternate one from each side along the rim - and hence are more subject to the continual deformation as shown in the above image) .
The new version, builds on the strengths of the earlier version. it offers the same superb aero gains by virtue of the excellent 42mm deep semi U shaped rim . But this year there are also new decal and new spoke choices also.
Aero wheels effectively offer free speed on the flats and descents and with the NEW K1-42A TOUGH we've bought this aero advantage within reach of many more riders.

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!
Hello Everybody bought a set and was happy with service wheels came quickly in very safe box so no chance of damage ,A good choice of colours of wheels and depths of rims, went for the 40 mm deep rims didn't want them to shallow or to deep and they look fantastic on the bike plenty of head turners when out on bike . performance the braking on rims good little less wear than carbon rims very slight weight gain than carbon but tougher in my mind and will not snap on pot holes , you might get slight dis-shape but wheels will be able to be fixed not like carbon wheels.
I bought some Kinetic-One wheels to replace my Shimano R501''s that were supplied with my Cannondale CAAD 8. Well first off they look great! Admiring comments from other cyclists at a recent sportive! They run quietly and do seem to roll better on the flat and downhill with no real difference from the R501''s when climbing. Must be the aero effect! Weight is about 1900g which is competitive for this wheel type / price point. I''m 6ft 2 and 82kg so weight wasn''t a key factor for me. They also seem to be robust having survived a number of significant pot hole encounters! So in summary would recommend!
My first set of K1-42s are still running brilliantly after at least 2500 hard fast miles so I'm getting my wife a pair for her birthday as she has been asking for months now! Keep up the good work, your wheels are truly awesome, they honestly roll as good as my Zipp 'event wheels'. Please do use my words, I tell everyone I meet who say to me 'Wow, your wheels look amazing' where I got them and that I think they are utterly brilliant. People can't believe the price point!
Attached is a recent photo of them on my training bike (red, white and blue Trek in the gallery), it's a bit of a comedy pose but you get the idea. I use them on this bike (retro I know but I love it) and also on my TT bike.
With my best wishes, Stephen.
have to say the wheels are very good, look amazing, seem very strong ( I need strong ) and roll very well, I would recommend them to any one looking for a great set of wheels to upgrade the usual suspects that come with a new bike !
have attached a photo of my work in progress ( blue pedals ! ) its a Ciocc 7003 Alu and carbon frame with Colnago Decals pretending to be a B-Stay Master, but I love her :) and the new wheels just set her off beautifully. I get lots of comments when out on rides since they went on. Thank you. Jon
