Aerodynamics can be maximised and weight reduced to 1597 grams approx by upgrading to the SUPERAEROLIGHT version with the lightest Bitex hubs and PSR Aero SL spokes: the most aero spoke available - anywhere!

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

Bought a pair in October 2018 on the recommendation of a family member who owns a set of deep carbons for TTs.

Superb set of wheels, after nearly 5 months of pretty shocking welsh winter weather, still dead true and roll smoothly. On par with the weight of the stock 20ish mm bontrager's I had on before, and although I can't measure the aero benefit, they certainly feel rather speedy when you're pushing the pace!

Fantastic communication throughout the buying process, with Andy recommending the 42SLs and a spec based on my requirements.

10/10 nuff said.

Charles - Derby

Excellent excellent Product and excellent service - though the courier was a day later than I paid for! Though thats not your fault i know. Thanks.

I had Campag Zondas on my 2015 SuperSix but I wanted to get some deep section wheels to see what difference they made. Most of the carbon wheels these days have an external rim width of 25mm plus. The gap between the chainstays on my bike is not big enough to take those wheels. I also wanted alloy rims and the wheels to be light. I saw these after surfing online and I'm really glad I did. I bought the SuperAeroLight option. The first ride I really noticed how smooth the bearings were - wow - what a difference. Always wondered what a decent pair of wheels felt like. I've really noticed that my legs are fresher after longer rides.

Fantastic wheels, sooooo smooth! Great service!

Matt - Gloucester

Andy lied to me, I didn't become better looking, more successful or intelligent, however, I did get quicker!

On a serious note, lovely wheels (K1 42SL), so much smother and feels faster than my old ones.

Susan Brown added another British Triathlon Championship yesterday, winning the Age Group Standard Distance at Leeds, so she now holds the "double". She was racing as usual on her Kinetic One wheels, which as usual were faultless and fast. The picture is the podium from Leeds, please feel free to use if you wish. (see gallery)

Neil Phelps - Wokingham

Great deep alloy wheels really well made and they roll superbly well . The customer service is excellent too. I would highly recommend Kinetic-One

Paul Beaumont - Enniskillen

I took the plunge and purchased a pair of K142SL's. Best decision I've made with regards to upgrading my bike. These wheels just keep on running! I've knocked over a minute off a 10 mile TT and have found I'm up with at the front when it comes to the bunch sprint. Even when it comes to climbing they're no slouch. Cheers Andy. Great product.

Andrew Henderson - Notts

Have just been out on my best bike for first time since fitting your 42SL wheels (hence delay with feedback). Well i must say that i was immediately impressed with how taut the bike feels, no flex when climbing and i seem more able to push a higher gear, well pleased! Please find picture of Planet X badged Van Nic pro road, Campag Athena groupset and your brilliant stealth graphic wheels. Many thanks Andy, Retford, Notts

Review: The wheels are excellent and did me proud at the recent World Duathlon Championships. They also look nice on my Felt bike (much better than Ottawa last year). As I’m not at the top end of cycling (just yet!), they are affordable but durable at the same time. My bike times are now getting quicker and one day they hopefully match my run times (which is where my strength is within Duathlon and Triathlon). I’m hoping to go to the World Duathlon Championships in Australia next year, if I can get some sponsorship.

Review: I decided on these a couple of months back after having researched several other wheel brands to upgrade to and decided to go with Kinetic-one on price and value for money. Chatted through what I wanted with Andy who was very helpful and decided on the K1-42SL. Performance wise they are great, giving a noticeable difference straight away, on a regular long ish route of around 50 miles I felt less fatigued and found I put in a quicker time. Rolling resistance is minimal and I found testing the freewheeling next to a couple of mates that I was rolling faster and longer so the aero design really does work. I ordered these in blue for the only reason that my bike is blue and was not overly bothered but must admit they make the bike look pretty stunning and I've had quite a few comments. Finally and importantly the customer service is brilliant. After a few miles one of the spokes was making a noise, phoned them up, wheel was picked up by courier and returned very quickly, a slightly under tensioned spoke being the culprit so full marks for customer service and communication. If you are thinking of buying these wheels I don't think you'll be disappointed!
