PLEASE NOTE THESE WHEELS ARE SIZE 650C FOR 650c BIKES ONLY!
INTENDED USE: Our "Do Everything" carbon wheelset. This wheelset is ideal for Time Trials, Triathlons, and also spot-on for sportives, bunch-racing, and general road work.
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 650c full carbon clincher version of our best-selling K155uc aero wheels. Fully handbuilt here at K1 and offered with a choice of spokes and hubs. Designed to be aero, to be strong and to be light. Standard model is approx 1540 grams and we have a sub 1375 gram option available!
This is the newest of our K1 carbon wheelsets. At 23-24mm wide, with a full carbon u-shaped rim profile - it is aimed at those riders who prefer an ultra-modern wider rimmed wheelset (but not too wide!). 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.
Ideal for tyres from 23c right up to 30c and beyond.
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 "real-world" 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.
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 older model bikes.
NOTE: If you are intending to race alpine descents in very hot weathers, 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 new 2018 full-carbons have 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!
