INTENDED USE: THE K1-42A TOUGH WHEELSET IS A TRUE HIGH PERFORMANCE WHEELSET AIMED AT HEAVIER RIDERS (90-130KG) OR LIGHTER RIDERS WANTING A VERY STIFF AND ROBUST AERO WHEELSET. NOW WITH AERO SPOKES AS STANDARD!
Ideal for Time Trialling, Tri, Training, fast commuting, and if you go for the RACE spoke option, they are great for fast Sportives and audaxes too.
Your wheels will be handbuilt to order here in the UK by Andy Morgan, owner and founder of k1 wheels. Turnaround time is 4-7 days!
Offered With Full 2 Year 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. About 6 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. But he only really knew he was onto something when he rode them to a top 50 finish out of 1000+ riders in the Dragon Ride. At 16 stone! (There he is posing in the image above!)
Since then we've honed and developed the concept into what has become the K142A TOUGH wheelset . Applying all our knowledge of aero wheels and adding in the key concepts that impart strength above all else.
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 42A 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 previous 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.
