2020 Kinetic-One K1-58UC Carbon wheelset


​​​ ​​



INTENDED USE: This wheelset is ideal for Time Trials, Triathlons, and also spot-on for all but the windiest of sportives/road riding and bunch racing. Designed for max-aero and max versatility.


Designed to be aero, to be strong and still at a very light 1645 grams. Or upgrade to the superaerolight version to reduce weight to 1590 grams.

Your wheels will be hand built in the UK by Andy Morgan, owner and founder of k1 wheels. Turnaround time is normally 7-11 days. Current build times shown at checkout)

At 25mm wide - it is aimed at those riders who prefer an ultra modern rim profile - critically without going too wide to cause frame clearance issues! The handling characteristics and strength of modern U rims is superb - even in pretty serious crosswinds - especially when compared to the V-rims of only a few years ago.

The 25mm rim is Ideal for tyres from 25c right up to 40c and beyond. Both Perfect for running tyres at lower pressure, whether you choose clincher or TUBELESS tyre setup!  And of course .......... arguably more aerodynamic and faster rolling than traditional hoops! Though this debate will continue to rage and rage!

In terms of rim width we think we've really hit the sweet spot at 25mm wide. We carefully explored all of the many possible widths that aero wheels are being developed in. We developed and continually honed our own testing protocols to this effect - and critically we looked at a whole raft of practical "real-world" issues too that many rim makers simply overlook.

For example frame spacing: Yes its possible to go wider than 23-25mm but at what point do wheels begin to compromise the frame. The last thing you want is to find that your carbon wheels rub your frame the moment you get out of the saddle! 23-25mm wide is in our view the best blend of performance and practical usability in our experience and that's why all our carbons are built within this width range.

Whether you intend to go wider or narrower - we'll have the right wheelset for you! And if you have a narrow clearance frame - we can special order in some 20mm rims for you and we do find that's the only solution for users of many brands of bikes.


NOTE: The 50/58UC wheelset is ideal for UK roads and descents in all but the hottest weathers. If you are intending to race very long descents in hot weathers (such as alpine summer sportives) or just want a more familiar braking feel - you may want to look at our  full-carbon 50FW  wheels run in tubeless format. Or our carbon clinchers with Alloy braking surfaces.. All full carbon clincher wheels (from all brands) do need more considered "pulsed" braking on long hot descents to prevent rims from heating too much (Our full-carbon 50FW has amongst  the highest temperature resistant rim tech available!).

The technology has come such a long way in recent years that most riders are now fine with full-carbons, and they are lighter of course. We just like to give our customers all the facts . In fact we have never had a single rim issue on any our carbon wheels - we think this is because we are very straight with people about their relative advantages and disadvantages!
