INTENDED USE: Sportives, Bunch races and Triathlons (from Sprint to IRONMAN distance.) This is our 'SUPERLIGHT' K1-45SL Deep Alloy wheelset. Available in several build options - with weights as low as 1698 grams per pair. Superbly light for a deep alloy wheelset. They also feature our superb and rather beautiful full matt black ‘graphite’ alloy rims.
Your wheels will be hand built to order here in the UK by Andy Morgan, owner and founder of k1 wheels. Turnaround time is most often 8-12 days. (current build times are shown at checkout).
This is the Limited edition version of our best selling alloy deep section wheelset! A high-end ALLOY aero wheelset for riders who want all the aero benefit and lightness of carbon - but want to stick with a more robust material.
The K1-45SL is incredibly versatile: a raceday wheelset, A 'Sunday best' set for your posh bike, and all-season/heavy load wheelset.
The standard AEROLIGHT option is built with our superb Italian sealed bearing Ambrosio hubs and PSR Aero spokes. The budget aero version uses more economical heavier aero spokes)
We offer various upgrades to spokes and hubs. For example - our recommended AEROFLOW build with Miche hubs uses the toughest and lowest drag hubs available anywhere!
And the Bitex SL hubs used on our SUPERAEROLIGHT build are among the lightest high-performance hubs available. Contact us if you’re not sure what’s best for you!
We also offer 3 spoke count options: 20/24 is fine for most riders up to around the 100kg mark. But for heavier riders (or those who are tough on their wheels!) we offer a 24/28 spoke super-strong option. For very light riders we also have a 20/20 version.
The use of such fabulous components enables us to produce a true "pro-level" multi-functional aero wheelset, at a reachable price point. And of course they are hand-built in Gloucestershire!!
Offered With Full Warranty and professional mechanic support in-house.
This wheel has a very specific place in our range (and in our hearts!). A super 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.

This was my first time buying new wheels and it was daunting to start with. However, speaking to Andy was the best thing I ever did. He spent 45mins talking me through the different choices, how my aims as a cyclist played an important part and most importantly never mad me feel like he was pushing me to go for the most expensive option.
The wheels arrived early and are really well built. They are stiff and feel quick when I put my foot down.
They look great too with stealth decals!
Couldn’t recommend Andy and Kinetic-one enough.
Outstanding Product and Service
Absolutely amazing service from the entire team at K1. Personal contact from Andy throughout your update on order and build status. Wheels arrived and are absolutely stunning up close. The K1-45SL are amazingly fast and light... These wheels are extremely well put together and are a joy to ride. Many Thanks!
I actually have 2 sets of these - one with track hubs for my singlespeed (that Andy built specially for me) and one for my Bianchi with gears. Both sets perform great and look great and I would recommend them. A Kinetic shop in Ireland would do well!
I purchased a set of wheels from you some 3 or 4 months ago. First impression was they
looked very good but I wanted to give them a good road testing before I made my mind up about them.
I am very pleased to say I think these wheels are great and I have no hesitation in recommending them
to a lot of people who have asked me about them.will be coming back to you when they need replacing
which I think will be along while off yet.thanks very much Bob G
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!
Was looking around for carbon wheels and then I saw these. They did a good selling job with what they wrote as I was a bit nervous about carbon wheel strength anyway - so it touched a nerve. I love these wheels. had them only 2 months so can't comment on long term durability yet - but they are still so true and really feel incredibly strong when riding them over bad roads etc. Bought them to race on but have to say that they are on my bike 24/7 already!
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.
My K1 wheels have been everything I could have wished for.I am currently training for a European event from Switzerland to London so have done plenty of miles with no problems.Not surprised that they are their best sellers.
You know you have good wheels when your mates have to pedal down hill to keep up with you...My K1's are excellent.
These are the second pair of wheels from Kinetic One and probably won't be my last! Great value upgrade to my triathlon race bike (the previous set went on my road bike) especially compared to the standard factory wheels that come on the bike when new. The wheels are a great compromise between strength, weight and aero performance. I also find the pricing to be the best value available compared to comparable products. Top it off with a good personal service from Andy it is difficult to find any fault at all.
Hi Andy, the wheels came yesterday and good timing, they are amazing, smashed PB for 10m by over 90 seconds, they just keep spinning so much more efficiently than the standard giant wheels that came with the bike. Seemed to make going uphill easier too. Thanks, Cheers, James
Hello Andy, after a weekend of excessive testing, I am absolutely happy with the wheelset, you have built for me.
We had some hard rides with long and steep mountains followed with a certain number of sprints.
After using quite a few sets of prebuilt system wheels (Mavic, Fulcrum, Campagnolo), I believe I found the one, that fits all my requirements.
Thanks again for building these great wheels for me!
Wheels arrived yesterday, after a couple of anxious days, Thanks you very much. Put them straight to work today in a local 65 km graded handicap. Dalton (son) finished in the front bunch from C grade with an average speed of 44 kph (27-28 mph) on his restricted u17 gearing. It was an extremely fast race today, and I was pleasantly suprised to see him still in the train that rolled over my lowly E grade bunch with 5 km to go. The only other junior to finish with the front group on the day was running unrestricted gearing. We are both extremely happy with the way the wheels preformed today. They certainly raised quite a few eybrows from the other juniors, most assuming he was running carbons. Will shoot you an update along with some photos after our nationals trip
Love them. They Feel a strong and solid wheel and roll really well! 👍
I wanted a light yet sturdy deep section wheel set which wasn't going to cost the world and what I got surpassed all my expectations, from Andy assisting me in developing the wheels I wanted (deep section with race spokes) right through to the delivery, the whole process was brilliant. As for the wheels themselves, again just brilliant, fast rolling, strong and very responsive, wheels I was able to trust right from the start, in a nutshell absolutely fantastic in every aspect.
Excellent wheels. . Very happy with them.. have had 600km spins plus all the training. . Very solid and free rolling.
The best wheels I have ever had, they've survived a crash in a race and many miles of brutal winter training. On training rides and in road races I'm always comfortably cruising past others on freewheeling descents. I'm not a particularly heavy rider either (11st 3lbs).
Just bought some of these - They will be replacing a pair of K1 wheels that I purchased from you just over 10 years ago (June 2009) and I have to say that they've been absolutely faultless. At the time a few hundred seemed a lot to pay for a set of wheels but they've covered well over 10,000 miles on some challenging road surfaces and haven't skipped a beat until recently when the freehub began to slip. A very shrewd investment and a testament to Kinetic One quality!
Loved the colour scheme of the decals from the first moment I saw them, so decided to take a chance on other reviews. Happy to say that the reviews I read were good and true. The wheels are very well built and to an extremely high quality! They are slightly heavy compared with similar on the market at this price, but, with the aero rim, the nice free wheeling hub, the ride is still fantastic! I love these wheels...they are fast, smooth and very pretty.
Excellent value for money, quality and looks. The wheels roll nicely, feel very firm and strong with no hint of flex and do look at least twice the price thanks to the modest graphics and bladed spokes. Would recommend them as TT, road or training wheels.
I've been running my K1 wheels since September 2014 for both long weekend rides and the daily commute. They still look as good as new and are rolling perfectly. The wheels are proving to be bomb proof as advertised, built reassuringly well, they remain tight and stiff as the day they arrived. Add the stunningly good looks and you have a fantastically priced set of top quality wheels. So, take the great experience I have had so far with these wheels and add the flawless service Kinetic-One provided in processing my order and delivering (updates by email all the way including the name of the delivery driver and the name of my neighbour who took the delivery as I was out!) and your left with one option. Buy these wheels now! A top end product at bottom end prices supplied by a thorough and professional UK company! What more do you want?
