2020 Kinetic-One K1-58/85UC : Full Carbon Clincher wheelset




INTENDED USE: This wheelset is ideal for both shorter and longer Time Trials and Triathlons. Where speed and aerodynamics and WEIGHT SAVING are king. This is our tried-and-tested, lightweight, full carbon deep wheelset.

Now with bladed aero spokes as standard - or upgrade to lighter and even faster hubs and spokes!


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).

The 58/85UC  deep wheelset is superbly aero, beautifully balanced, and reassuringly well constructed from industry standard Japanese carbon. 

The 58mm semi-toroidal front wheel is both superbly aerodynamic and extremely light.(this is the advantage that full carbon offers) The rim shape gives it superb cross-wind handling characteristics too.

This is coupled with our ultra-deep rear 85mm deep rear - to minimise drag and give you every watt of power - and at superbly low weight. As little as 1670 grams a PAIR  in its lightest build option.

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 23mm wide 58/85UC's 's are built around our modern "semi U" shaped structural carbon semi-toroidal aero rim. designed to run best with 25c to 40c wide tyres but will also run 23c tyres fine).  The rim is designed to cut through the air going forward, whilst maintaining a superb lateral integrity to cross-winds across a full range of wind "yaw" angles.  

In terms of rim width we think we've really hit the sweet spot at 23-24mm 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 issues too that many rim makers simply overlook. For example frame spacing: Yes its possible to go wider than 23-24mm 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! 23-24mm wide is in our view the best blend of performance and practical usability in our experience.

PLEASE NOTE: if you have a narrow clearance frame - we can special order in some 20mm wide rims for you and we do find that's the only solution for owners of many older bikes.

Very pleased with the feel and results of the wheels. I'd like to think I've improved over the last year but a 54 second PB on a 5 mile TT must have had something to do with the wheels. It was the worst kind of windy ones, where the place where it should have been with the wind was quite sheltered, and heading back is an open crosswind across the flat fens! Wheels didn't give any cause concern in that wind, so very happy. Many thanks for all your help again
