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 the brand new, lighter, full carbon version of our 55/80c carbon-alloy wheelset.
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!
The 55/85UC deep wheelset is superbly aero, beautifully balanced, and reassuringly well constructed from top end t800 UD carbon.
The 55mm 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 1650 grams a PAIR in its lightest build option.

The 23mm wide 55/85UC'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 users of many brands of bikes (Notably Scotts for example!)
