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.
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.
Designed to be aero, to be strong and at 1525 grams in the standard “Aerolight" version (with a 1460 gram SUPERAEROLIGHT option available) ........ to be extremely light too.
Or go for our newest hub option: The AEROFLOW version. Built with supremely reliable and ultra-low drag MICHE PRIMATO Italian hubs. In fact these are the fastest rolling hubs available in recent independent tests. More>>
Your wheels will be hand built in the UK by Andy Morgan, owner and founder of k1 wheels. Turnaround time is usually 7-11 days (exact times shown at checkout).
At 25mm wide rims it is aimed at those 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.
Optimised for 25-28mm tyres . Perfect for running tyres at lower pressure, whether you choose clincher or TUBELESS tyre setup!
In terms of rim width we think we've really hit the sweet spot. Our entire rim brake range for this year is 25-26.5mm wide. We carefully explore all of the many possible widths that aero wheels are being developed in. We develop and continually hone our own testing protocols to this effect - and critically we look at a whole raft of practical "real-world" issues too that many rim makers simply overlook.
Yes its possible to go wider but at what point do wheels begin to compromise the frame - especially on older rim-brake frames. The last thing you want is to find that your carbon wheels rub your frame the moment you get out of the saddle! 25-26.5mm wide is in our view (and long experience) the best blend of performance and practical usability.
Whether you intend to go wider or narrower - we'll have the right wheelset for you! And if you have an even narrower clearance frame - we can special order in some 23mm or even some 20mm rims for you and we do find that's the only solution for users of many older bike models - such as older Cervelo's for example.
NOTE: These wheels are ideal for UK roads and descents in all but the hottest weathers. If you are intending to race very long descents in hot weathers (such as continental summer sportives or just want a more familiar braking feel - you may want to look at our full-carbon filament-wound wheels. All full carbon rim-brake wheels (from all brands) do need more considered "pulsed" braking on long hot descents to prevent rims from heating too much (Our full-carbon filament-wound rims have amongst the highest temperature-resistant rim tech available!). Keep it safe and keep it simple: If you are in any doubt in unfamiliar conditions - Use your Alloys that day. We also advise avoiding latex inner-tubes in unusually hot conditions and upgrading brake-blocks to SwissStop Black Prince.
The technology has come such a long way in recent years that most riders are now fine with full-carbons, and they are lighter of course. We just like to give our customers all the facts . In fact we have never had a single rim issue on any our carbon wheels - we think this is because we are very straight with people about their relative advantages and disadvantages!

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.
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.
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.
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 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 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 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.
Lovely self assured wheels that roll brilliantly
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.
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.
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.
Beautiful wheels! Understated elegance and added speed. What's not to love!
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 .
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.
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.
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.
