INTENDED USE: Our "Do Everything" carbon wheelset. This wheelset is ideal for Time Trials, Triathlons, and also spot-on for sportives, bunch-racing, and general road work: marrying maximum performance and maximum practicality.
Now in it’s fourth year of evolution - The 50UC continues to be one of the most popular wheelsets we produce and is an ideal upgrade for athletes seeking quality British handbuilt wheels on a ‘sensible’ budget.
- The standard "AERO" version with its Italian Ambrosio hubs and 3mm blade spokes is for those concerned more with all out aero than saving a few grams.
- The “AEROLIGHT” version uses the same hubs but invests in lighter aero spokes to get weights down for more hilly/mixed riding.
-Or upgrade to our superb new AEROFLOW build with PSR aero spokes and the lowest drag hubs available anywhere, the Miche Primato. These add a little weight but being so fast and so very durable does make them a fantastic all round investment. Especially for heavier riders or those riding in all weathers.
- If you go for the SUPERAEROLIGHT build at 1485 gram then you really are creating a wheelset that is superbly aero and extremely light too - by any standard!
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 7-11 days. (current build times are shown at checkout).
Aimed at riders who prefer an ultra modern rim profile - critically without going too wide to cause frame clearance issues! The handling characteristics and strength of modern U rims is superb - even in pretty serious crosswinds - especially when compared to the V-rims of only a few years ago.
Ar 25mm wide, it is optimised for more modern bikes and is ideal for tyres from 25mm, 28mm, right up to 40mm and beyond. Please make sure your frame can take a wider rim if you go for this option! Or contact us if you’re not sure... we do like to help our customers get it right first time.
Perfect for running tyres at lower pressure, whether you choose clincher or TUBELESS tyre setup! And of course .......... far more aerodynamic and faster rolling than traditional hoops!
In terms of rim width we think we've really hit the sweet spot. 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 "real-world" issues too that many rim makers simply overlook.
AND IF YOU NEED NARROWER RIMS: we'll still have the right wheelset for you! And if you have an even narrower clearance frame - we can special order in some 23mm wide or even 20mm wide rims for you and we do find that's the only solution for users of many older bike models.
The 50UC wheelset is ideal for UK roads and descents in all but the hottest weathers. If you are intending to ride/race very long descents in hot weathers (such as alpine summer sportives) or just want a more familiar braking feel - you may want to look at our full-carbon filament wound wheels.. and please do read our page on safe braking and care for your carbon wheels HERE

A friend put me onto this brand and I plumped for their carbon wheels after several useful email exchanges. My wheels are now a year old and I am very pleased with them. Deservedly 5***** in my opinion.
Having previously bought a Kinetic-one bike it seemed a logical upgrade to go for these wheels. (They were about half the price of the Reynolds wheels they also do and I wasn''t sure I''d notice the difference to be honest - so i thought i''d save myself almost a grand and buy these!) They are Superfast wheels and very strong.
just returned from doing the cat in Cheshire ,my first decent distance with my new wheels
absolutely brilliant lovely smooth ride and the company great to deal with.
Quick no hassle friendly service.Arrived on time and looked great.
And most importantly they made me go faster !!
Very happy and would recommend especially if your on a budget .
Beautiful wheels! Understated elegance and added speed. What's not to love!
I first contacted Andy with may questions about his wheels and it wasn't long before he put my mind at rest. I was so impressed with the amount of knowledge he had I didn't hesitate to purchase a pair of carbon wheels with alloy brake surface. The wheels are just great and a big improvment over my fulcrum racing 3's I had. They are stiff with no flex espeically up the hills. They roll fantastically and what surprised me the most was how much better they were up the hills too. The service is second to none and Andy was always there if I had anything to ask. Cracking wheels considering the price and great looking to. Oh and very light too!!! Thanks again Andy.
I decided on the K1 50s and the intro offer was really good value. The wheels perform brilliantly. Really smooth, stuff and cornering feels great. After a couple of weeks I found one of the spoke nipples was loose. I emailed Kinetic one and they had the wheel picked up quickly. Few days later it was back with me and all sorted. Communicstion was great, and I'd go as far as saying their customer service was just as good as their wheels. I would recommend these wheels to anyone who wants great performance, great looks and a fantastic price. Very very happy.
Just wanted to pass on more thanks to you! I completed the iron distance Outlaw triathlon on Sunday, in the most horrific conditions! I saw plenty of people blown clean off their bikes, as well as many more blown off course. I however was very happy with my medium section wheelset! Just as you advised and predicted, they were a perfect compromise for when you only have one wheelset.
No complaints whatsoever from me. As and when I'm in need of another wheelset, I won't be looking anywhere else.
Lovely self assured wheels that roll brilliantly
I love the wheels. They are great value for money and after getting to stick 60 miles into them over the weekend they are exactly what I was looking for. Aerodynamic enough to cut through strong winds and light and stiff enough to glide up the Welsh hills and respond when I put the hammer down. Brilliant set of wheels.
I totally love these wheels - full stop. I'm 75Kg and have done ~1000 miles on terrible (Wilts/Glou) roads and they are still perfectly true. They must have been properly pre-stressed because I heard not a single spokey ping when I first used them (which is a first for me).
Of course they are stiff and light but, considering their deep profile, I was very pleasantly surprised by how comfortable they are. This is very apparent +4hrs! I went tubeless with Schwalbe pro one - set up was fairly painless. They are definitely faster too :).
Another surprise is braking - it is amazing how much better the tech is than in the '90s when I rode some full carbon Corima wheels and nearly killed myself in the process. With the supplied pads, braking is... simply not an issue - in the dry, there is a faint squeal but definitely not an annoying one.
For me, they're worth every penny and if I were to break them and require another set of wheels then, I would definitely be back.
I bought these on recommendation from a friend. I've nothing to compare them with as they are my first and only (ever i suspect) pair of carbon wheels. I do know they make me go faster and make my bike look very nice. Being able to choose the finish colour is a very nice touch. Thank you.
I do love these wheels. It did take some serious soul-searching before i finally hit the button and went for wider rims. (I used to race on 16mm rims back in olden-times!) I did have a few problems with setup as My Tektro brake calipers could not really handle the width of the rim. As soon as I put some Shimano brakes on all fine and I have not looked back - 28c tyres are so comfortable too. Brave new world!
I carried out a lot of research before deciding to purchase the K155UC carbon clinchers wheels with 28mm wide tyres. I decided to go for lighter Sapim CRray on Bitex hubs, so they would be lighter than my existing wheel set. I have found a marked increase in speed on the flat using the same effort / power & down hill speed has increased also. Really like how they look. So all in all I'm very happy with my purchase at a very competitive price & would highly recommend these wheels to others.
Great wheels, they look and feel great to ride. A great improvement on the standard wheels that came with the bike. Excellent communication and delivery information.
Didn''t have the money for Zipps - wanted wheels that were aero, and a bit nice - but also had to be tough - as i''ve not alot of dosh! The kinetics have done me proud in sportifs and doing a few tri''s. For the money they are really something. They did forget to include Quicl Releases - but i rang up and they came next day.
