INTENDED USE: This is our "max-aero multi-functional Sportive/TT/Tri" carbon wheelset. It features an alloy braking surface for reassurance and for all-round versatility. Ideal for road work and also for Time Trials, Triathlons, and also spot-on for bunch racing.
Performance characteristics are maximised through combining a slightly deeper rear rim (for better aero performance) - with a shallower 50mm front wheel, for perfect handling in technical/windy conditions.
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)
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.
These are our stunning new K1 Carbon 50mm deep front /58mm deep rear - 700c clincher wheels (for inner tubes and tyres). For Road or Time Trial or Tri bikes. They have alloy braking surfaces. This is the new deeper version of our best-selling K1-50c wheels - new rim depth but same spec and equipment options! Includes lovely new 20/24 spoke choices - some lighter, some more aero, and some in superb new colours to make your bike simply stunning!
The K1-50/58 mm wheelset is aimed at Road racers, sportivistes, Triathletes and Time Triallists, where aero is king but you don't want to add the weight of really deep rims to your bike. Also ideal for even windy sportives and bunch races - We've also 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 50/58'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.
We can supply them with a range of clincher tyres - NOW INCLUDING what we reckon is the fastest all-round clincher combination known to humankind: This is the ContiGP5000 tyres, paired with latex inner tubes. The combination of rolling resistance tests and formal aerodynamics assessments affirms this is the best way to go for all out speed. And when we say "all-round" we mean for real world riding. There are slightly faster tyres ... but they won't last 5 minutes on UK roads! (The GP5000's have puncture protection and are strong as well as blisteringly fast).
Unlike the vast majority of alu-carbon deep-section aero wheelsets, the K1-50/58c's are also designed to be super-strong. The inclusion off alloy brake tracks and hence an alloy cross sectional structure means they are perfect for racing and still strong enough to train on.
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!)
