INTENDED USE: This is the new lighter, 58mm deep version of our "Best-selling Multi-functional Road/Tri"/TT carbon wheelset. With its full carbon structure - combined with an alloy reinforced braking track and SAPIM SPOKES AND ITALIAN MICHE HUBS AS STANDARD (with a stunning £30 upgrade available to PSR 3.2mm AERO BLADE spokes!) we are very proud of the new 58C.
This wheelset is ideal for Time Trials, Triathlons, and also spot-on for all but the windiest of sportives/road riding and bunch racing. 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.
The 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.
Unlike the vast majority of alu-carbon deep-section aero wheelsets, the K1-58c'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!)
