This wheel has a very specific place in our range (and in our hearts!). A semi deep section lightweight alloy wheel is the perfect "do-everything-wheelset" for multi-gradient triathlons, time trials and even sportives. Designed to run best with 25mm or 23mm tyres.

Light enough and comfortable enough to get you up those hills in good shape, (with silky smooth bearings to help even more), and aero enough to gift you free-speed on the flats and the downhills. .

We achieved this combination of aero/strength/lightweight - by marrying; the 
wonderful lightweight kinetic-one aero rim; with superlight hubs; and Sapim CX Ray spokes (which have the distinction of being the lightest, strongest and most aero of all aero spokes

Review: Bought some of these wheels back in June as a present for my wife . Correspondance with Andy was first class . These wheels look fantastic , and they perform beautifully too . She has managed to get PB''s on nearly every ride this summer ( i keep saying it''s the wheels that deserve the credit and not her !!!) . Can''t recommend these wheels , or Kinetic-One enough .

Review: Very pleased. Strong, stiff, fast - all I need. 1000 km under my belt with them now.

Review: I can only add to all the good things said about these wheels. Tremendous.

Review: Only had a couple of short rides on the new wheels, but first impressions are very good. They feel and ride much lighter than my Fulcrums and they are stiff with no flex or brake rub when hammering it out of the saddle up the climbs, where the lightness is really noticed. I have also hit a few pot holes ( hard not to around here) and no problems there so they are tough as well. Looking forward to getting a few decent miles in on them. Overall then .....5 stars , excellent value for money and to top it off Andy is a real good bloke and a pleasure to deal with. Mike

Review: Coming from stock Alexrimms DA22 to these is a massive transformation to a 2009 GT Series Three. Had these wheels just over 6 months now. K1's spin up nice and easy, holding the pace without complaint. Instantly saw average speed jump by 3-4km/h. Rode nicely along national cycling route 23 in the Isle of Wight which is not all tarmac and they stayed true too. They are certainly up to to a daily ride on British roads. Riden with Michelin Pro3s with Schwable light tubes. Tricky to get on/off the wheel following 2 flats but that is down to the tyre. About to try Conti GP4000s with Conti Race 28 Light tubes. Seem to be a lot easier to get on and off. Highly recommend these wheels. Excellent communication and discussion with Andy regarding other wheelsets in similar price brackets. Wouldn't hesitate to buy another pair of these for race only.

Review: I ordered my ultralights over the web, after considerable helpful advice from the folks at K1. I was NOT disappointed. They arrived beautifully packed, and ready to go. I was taking my first ride within minutes and MAN what an upgrade from the stock Fulcrum 5's that came with my bike. They ride much smoother, but tougher, and seem to hold momentum much more easily. I feel like I picked up 1k/hr from them, but more importantly, my daily ride is more engaging and fun. They are simply a pleasure. I also like the fact that they are "different" from the stock upgrades out there - and they look great. Highly recommended.

Review: Truly excellent!!!! I had my doubts when I read the specs on these wheels and then the price, surely to good to be true! As light as any wheelset on the market, but hundreds of pounds less! After quick and sound advice from the Kinetic team I took the plunge....and never regretted it once! The box when it came was so light I thought it was empty! The wheels look fantastic on my Cube bike and fit my wireless bike computer module fine (even with the aero spokes). I improved my average speed by 2 mph on my first ride, even in a strong winter headwind, and the wheels shook off even the harshest of the South Wests potholes, impressive for such a light wheelset! The wheels hold up well in crosswinds, with no great effect on your heading as is the problem with other lighter wheels with bigger rim sizes. Even these strong winter winds do not knock me off my direction of travel! The hubs on both front and back are incredibly smooth, and roll with a great speed! I had to use my own kit to secure the wheels to the frame as those supplied were a little too small but that caused no great problems. I have had a bad puncture which isn't the wheels fault, just a shame I can't use them until it is fixed which is killing me! Overall, great service, superb wheels for road riding, or triathlons. I look forward to Olympic distance triathlons next year using these wheels! I have yet to ride a considerable distance on them but as soon as the puncture is fixed then I will crank up the miles and review separately. If you want lightweight, strong and value for money wheels, get these bad boys!!!!!

Review: Brought these last year but not had them on the bike over winter. Have now done around 300 miles and have to say they are fantastic(which is why they are now on my new bike)for the price and customer service you can't go wrong. 100% reccomend these wheels to anyone.
Alasdair McKinley - Edinburgh
Review: Simply fantastic - as I bought a pair of kinetic-one wheels some years ago and they did me proud so that was sufficient recommendation to try another set of their wheels. Glad i did - I think it would cost at least several hundred pounds more to get a wheelset any better than this.

Review: Took a bit of a punt on these - not having had any kit like this since my racing days back in the day. Seriously impressed with these wheels. Had them a few months and they attract lots of attention and they roll like silk. Rob
