INTENDED USE: The 80c's are about all out max speed achieved through cutting edge tech. With their super deep U-shaped 23mm wide rim, bladed aero spokes and ALLOY braking surface, this wheelset is ideal for Time Trials and Triathlons, but is too deep for sportives and road bikes.
With alloy braking surfaces you don't need special brake pads and braking is better than with Full-carbon clinchers - particularly on very long descents.
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 K1-80mm wheelset is new to our range and is aimed squarely at Triathletes and Time Triallists. We've designed them to be a super-tough "investment" wheelset. We believe carbon wheels should be as strong as alloy wheels. (more on this below!)
The 80's are built around our modern "semi U" shaped structural carbon semi-toroidal aero rim (which is designed to run best with 25mm wide tyres but can also take 23's and 28's). The rim is designed to cut through the air going forward, whilst maintaining a superb lateral integity 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 rims for you and we do find that's the only solution for users of many brands of bikes (Notably Scotts for example!)
Unlike the vast majority of carbon deep-section aero wheelsets, the K1-80c's are also designed to be super-strong. Perfect for racing and still strong enough to train on. Within the carbon rim is a structural alloy cross section that gives these wheels hugely enhanced strength compared to most carbon wheels in the market.
This is by no means the lightest wheelset on the market - and are by no means our lightest wheelset! This is because we have gone for strength and durability as our primary objective. There are very few carbon wheels on the market which are designed in this way and with this objective in mind!
