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. At the same time these wheels have an additional benefit compared to carbon wheels: Their durability and strength.
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 - see the summary graph of the Zipp Labs research findings below!) :

|FREEHUB FITTING||SHIM/SRAM 7/8/9/10/11 or CAMPAG 9/10/11|

My Sunday best wheels - never let me down - 8 sportives last year and almost most as many training miles as i intended to do. Strong too.

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 .

Spot on set of wheels. I use them in sprint tri''s right through to century sportives and they really feel like the right wheels for every job. you never feel you''re losing out. Again i guess that''s the aero and lightweight thing! Tough as old boots. i''ve given them a right lamping on our very knackered roads.
Gary - Mallorca
Very pleased. Strong, stiff, fast - all I need. 1000 km under my belt with them now.
Steve Clarke - MK
I can only add to all the good things said about these wheels. Tremendous.

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. Thanks Kinetic Two Mike

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.

Service = excellent Delivery = well packaged and when stated The product to look at = wheels look the business! To use = admittedly the previous wheels were bog standard but even still the difference was ammence! More speed everywhere, especially on climbs. Avg speed has increased by 3mph! Went from mid table in competitions on the bike leg to now getting into the top 10 percent. With the old wheels I struggled to roll past 60 mile rides and now I've done 100+ ones. With the exception of my bike (which I won't be sending a pic of as although I love it, looking at your gallery, I would feel bad if I saw a pic of mine!) the single best bit of kit I've brought to improve my tri performance and all round biking satisfaction!

I've done well over 1000k on these and they are terrific. I'm quite heavy and really notice that I am pulling better into a headwind and cresting hills with less effort. They seem to want to roll all day. Ride is firm but not harsh. Service and advice from Andy is what swayed me to buy - couldn't have been more helpful.
